INTRODUCTORY LECTURE

AN OVERVIEW OF THE CONSERVATION STATUS OF EAGLES OF THE WORLD

L. Kiff, The Peregrine Fund, 5668 W. Flying Hawk Lane, Boise, ID 83709. The number of recognized genera of eagles has declined slightly over the past century, but the number of recognized species has increased, partly due to the advent of molecular genetics. Classifications of eagles by the IUCN conservation status criteria are maintained by BirdLife International and the Global Raptor Information Network (“GRIN”). According to these sources, there are 67 (BirdLife) to 76 (GRIN) species of extant eagle species in 19 to 21 genera. (GRIN recognizes 9 species, mostly from the genus Spilornis, which are regarded as subspecies by BirdLife International). According to these schemes, eagles fall into the following categories (GRIN totals in parentheses): Critically Endangered: 3(3); Endangered: 3(8); Vulnerable: 12 (11); Near Threatened: 12(13); Least Concern or Lower Risk: 37(32); Data Deficient: 0(9). Based on GRIN, the rarest eagle species (Critically Endangered, Endangered, Vulnerable, or Near Threatened) are distributed unevenly by zoogeographic region, as follows: Indomalayan (19), Afrotropical (8), Palearctic (5), Neotropical (5), Australasian (2), and Nearctic (1). Although direct persecution of eagles, especially shooting, occurs almost everywhere, the intensity of other important threats varies by region, with habitat loss or degradation being most important in all areas, especially in tropical latitudes, and secondary poisoning ranking high in the Afrotropical, Palearctic, and Nearctic Regions. Among the most pressing needs for global eagle conservation are basic research on the poorly known Spilornis and Nisaetus taxa in the Indomalayan Region, and, on a global basis, habitat preservation, environmental education, and the termination of lead ammunition manufacture.

COMMUNICATIONS EAGLE CONSERVATION AND RESEARCH BY THE PEREGRINE FUND: MADAGASCAR SERPENT EAGLE, MADAGASCAR FISH EAGLE, AFRICAN FISH EAGLE, HARPY EAGLE, AND OTHERS. R. T. Watson. The Peregrine Fund, Boise, USA. The Peregrine Fund rediscovered the Madagascar Serpent Eagle (Eutriorchis astur) in 1993, nearly 60 years after the last reliably confirmed sighting of this species. Our current work aims to understand the ecology of the species and use this information to help establish a nationally protected area of habitat for serpent eagles and other highly threatened biodiversity in northern Madagascar. Our work to conserve the endangered Madagascar Fish Eagle (Haliaeetus vociferoides) spans nearly 20 years of effort and includes in-depth study of the species’ distribution and abundance and factors affecting them, community-based conservation of critical habitat, experimental species management, and ongoing population surveillance. The African Fish Eagle (Haliaeetus vocifer) is widespread on continental Africa and considered a species at lower risk. The Peregrine Fund is monitoring a population nesting on Lake Naivasha because the historical study begun in the 1960s by Leslie Brown offers long-term data for comparison with the contemporary landscape, and the species appears now to be subject to numerous effects associated with a recent horticultural industry which grows flowers for export and consumption in Europe, including water abstraction, contamination with herbicides, pesticides, and fertilizers, and the effects of a large immigrant human population of laborers. The Harpy Eagle (Harpia harpyja) is considered near threatened and has been the subject of experimental restoration by The Peregrine Fund in the Maya Forest of Belize, Guatemala, and Mexico, as well as in the Panama canal watershed. Current work includes monitoring captive raised eagles released to the wild, and studying the species’ population biology in an intact part of its range in Panama. Human persecution and habitat loss are the most important factors limiting the species’ survival. The Peregrine Fund also provides assistance with other eagle species under study and conservation worldwide including the Philippine Eagle (Pithecophaga jefferyi), New Guinea Harpy Eagle (Harpyopsis novaeguineae), Pallas’s Fish Eagle (Haliaeetus leucoryphus), and Grey-headed Fish Eagle (Ichthyophaga ichthyaetus).

STELLER’S SEA EAGLES (HALIAEETUS PELAGICUS) IN MAGADAN DISTRICT, RUSSIA OVER THE PAST 18 YEARS

1. Utekhina1, E. Potapov2, M. McGrady3 & D. Rimlinger4 1Magadan State Nature Reserve, Magadan, 685000, Russia. 2Bryn Athyn College, Bryn Athyn, PA 19009, U.S.A. 3Natural Research, Ltd, Brathens Business Park, Hill of Brathens, Glassel, Banchory, Aberdeenshire AB31 4BY U.K. 4San Diego Zoo, 2920 Zoo Drive, San Diego, CA 92101 U.S.A. We studied occupancy and productivity of Steller’s sea eagles (Haliaeetus pelagicus) in the Magadan District of Russia since 1991, concentrating mostly on the Magadan State Reserve (zapovednik) and the coastal areas nearby. We were aware of and visited at least once during the study period 281 nesting territories. We were unable to visit all nests in all years, but since 1997 we have collected data from about 100 nests per year. Nesting territories could be divided into sites on rivers or sites on coasts and those which fell within the more strictly protected areas of the zapovednik and those outside of its boundaries. Coastal sites could be along shallow bays with large littoral mudflats at low tide or along areas of deep water with little or no littoral zone. Some coastal nesting territories were near sea bird colonies. We report on occupancy and productivity parameters and examine the influence of territory characteristics on these. Overall productivity was significantly less on rivers than on the coast. On the coast, nests on shallow bays and near sea bird colonies were more often occupied and were more productive than territories on deep water. We discuss our findings in relation to current estimates of the status of the Steller’s sea eagle and identify useful avenues of research as well as conservation efforts that might benefit the eagles.

STATUS AND CONSERVATION OF THE GREAT PHILIPPINE EAGLE D. Salvador. Phillipinne Eagle Foundation, Mindanao, The Phillipinnes. The Great Philippine Eagle (Pithecophaga jefferyi) is regarded as one of the most endangered eagles in the world. Habitat loss and human persecution continue to impact the species adversely. These problems are complicated further by a number of human-induced factors. Yet despite these obstacles, sustained conservation initiatives over the years have began to yield positive results. The current population status of the species and threats are outlined in this report. In situ and ex situ actions associated with the conservation of the species show how these threats are being addressed. Recent developments and plans to strengthen recovery goals for the species are also presented in this paper.

STATUS AND CONSERVATION OF EAGLES IN NEPAL A. Chaudhary1, H.S. Baral2 1Bird Conservation Nepal, Kathmandu, Nepal, 2Himalayan Nature, Kathmandu, Nepal For a small landlocked nation, Nepal has high bird diversity due to its diverse altitudinal and habitat range. There are 864 species of birds recorded from Nepal with nearly 600 breeding species and 31 globally threatened species. Of the 74 species of Eagles found in the world, 26% (19 species) have been recorded in Nepal. Among them, 6 are globally threatened and 3 nationally threatened. Aquila hastate, A. clanga, A. helica and Haliaeetus leucryphus have been listed as vulnerable and Ichthyophaga humilis and I. ichthyaetus as near threatened in the IUCN Red List. In addition, Aquila rapax, Haliaeetus albicilla and Hieraatus kinerii have been recorded as critically endangered, endangered and vulnerable respectively for Nepal. Food shortage, poisoning and habitat destruction are the key threats to eagles in the country. No concrete work specific to eagle conservation has been carried out. Nepal does not have any eagles in its list of protected animals, however, this list is in the process of being updated. Nepal now has nine national parks, three wildlife reserves, one hunting reserve, four conservation areas and eleven buffer zones covering an area of 28,998.67 sq. km that is 19.7% of the total area of the country. Important Bird Areas (IBAs) have also been identified for Nepal and concentrated conservation work is ongoing in many IBAs. Nepal has a total of 27 IBAs covering 18% of country’s land area, 14 support globally threatened eagle species. Nepal also has eight Ramsar sites, 4 of which support globally threatened eagle species. The conservation of these sites hold the key to conservation of eagles in Nepal.

Universidade Federal de Ouro Preto – Programa de Pós-Gradução em Ecologia de Biomas Tropicais Entre os 27 estados brasileiro, Minas Gerais é o quarto em extensão territorial, com uma área de 586.528 km², incluindo três biomas brasileiros: o Cerrado, a Mata Atlântica e a Caatinga. Entre os anos de 1998 e 2009, somamos informações sobre as espécies de águias ocorrentes no estado, identificando áreas de ocorrência e reprodução, coletando dados descritivos sobre a biologia e ecologia, além de elaborar estimativas populacionais em distintas regiões do estado. Entre estas, a única que não está inclusa na lista estadual de espécies ameaçadas é a Águia-chilena (Buteo melanoleucus), que apresentou tendências sinantropicas, se reproduzindo e caçando no interior da área metropolitana de Belo Horizonte. O Uiraçu-falso (Morphnus guianesis) foi registrado em apenas uma localidade, quando um casal foi observado no Parque Nacional do Caparaó em 1997, podendo ser considerado juntamente com a Harpia (Harpia harpyja) as espécies mais ameaçadas. A ultima foi considerável provavelmente extinta no estado, com registros históricos para a década de 60, e os últimos registros da espécie são de indivíduos isolados documentados no município de Cataguases em 1996 e na região de Tapira em 2006. No entanto essa espécie pode ser considerada extinta no Parque Estadual do Rio Doce, maior remanescente de Mata Atlântica do estado com 36.000h, após a realização de quatro anos de censos (2004-2008), não foi mais registrada na reserva. A Águia-cinzenta (Harpyhaliaetus coronatus) é a única águia inclusa na lista nacional e mundial, registramos a espécie em 19 localidades do estado e quatro sítios reprodutivos, sendo que apenas um ninho se encontra em uma unidade de conservação. As três espécies do gênero Spizaetus são classificadas como em perigo de extinção no estado. Observamos Spizaetus ornatus em 10 áreas diferentes e dois sítios reprodutivos foram documentados, sendo que um destes ninhos encontra-se em uma área de preservação. S. tyrannus foi observada em 11 áreas, mas apenas um ninho, sendo o primeiro para

o estado. Registramos S. melanoleucus em 08 locais e dois sítios reprodutivos em áreas de preservação permanente. Para estas espécies individualizamos como ameaça primária o desmatamento e a descaracterização vegetacional em seus sítios de nidificação. Associada a ameaça principal, a perseguição e a caça aparecem como problema secundário, o que foi documentado através de entrevistas locais. Como estratégia de conservação imediata é preciso guarnecer proteção total aos sítios de reprodução pré-determinados, além disso, iniciar programas de educação ambiental, visando o descimento de ameaças secundárias como a caça.

E-mail: [email protected]; [email protected] EARTHMATTERS. ORG. P.O Box 15251, Gainesville, Fl 32604, USA. Una proporción significativa de las especies de águilas amenazadas en Venezuela, se encuentran protegidas, debido a que parte de su distribución geográfica está dentro de áreas naturales bajo protección (parques nacionales, monumentos naturales, refugios de fauna, reservas de biosferas y reservas forestales). Aunado a esto, existen herramientas legales a escala internacional y nacional, que incluyen especies particulares a las cuales se confieren diferentes tipos de resguardo. En el ámbito internacional, la Convención sobre el Comercio Internacional de Especies Amenazadas de Fauna y Flora Silvestres (CITES) incluye mucha de las águilas en sus apéndices (I, II, III), según el grado de amenaza, debido al comercio internacional. En Venezuela, existen dos (02) decretos que protegen a las especies de águilas que presentan un grado de amenaza: Decreto Presidencial 1.485 (Venezuela 1996a) que declara el listado de animales vedados para la caza y el Decreto Presidencial 1.486 (Venezuela 1996b) que señala el listado oficial de especies en peligro de extinción.

A BRIEF REVIEW OF THREATENED EAGLE SPECIES IN JAPAN AND THE STATUS AND TRENDS OF THE JAPANESE GOLDEN EAGLE (Aquila Chrysaetos japonica)

T. Ozawa The Society for Research of the Golden Eagle. A Brief Review of Threatened Eagle Species in Japan and Their Threats. Five eagle species are considered threatened in Japan: White-tailed Eagle (Haliaeetus albicilla), Steller’s Sea Eagle (H. pelagicus), Hodgson’s Hawk-Eagle (Spizaetus nipalensis), Golden Eagle (Aquila chrysaetos), and Crested Serpent Eagle (Spilornis cheela). Except the Steller’s Sea Eagle, a winter visitor in Northern Japan, other four species are resident breeders in Japan. Although all these species are threatened by habitat distraction and alteration, the two forest species, the Golden Eagle and the Hodgson’s Hawk-Eagle, appear to be most affected by deforestation in mountainous areas. The range of the Crested Serpent Eagle in Japan is limited in some islands and its small population seems to make the species vulnerable. In addition, lead poisoning attributed to the consumption of deer carcasses contaminated with lead shots (mainly two Sea eagle species) and the construction of wind power turbines in their habitats (all but the Crested Serpent Eagle) are great threats to raptor survival in recent years. The Status and Trends of the Golden Eagle (Aquila chrysaetos japonica) in Japan. The Golden Eagle (Aquila chrysaetos japonica) is an Endangered Species in Japan with its estimated population of around 500 including about 175 pairs, and its urgent conservation has been required. However, as the fact that an eagle nest site was first found and scientifically recorded in 1937 shows, it has been just less than 70 years since the start of research on the Japanese Golden Eagle. In Japan, the Golden Eagle is found in very steep and deep mountainous areas. This probably made the surveys of the species extremely difficult at the time under the poor condition of traffic networks including forest roads. In 1980, the Society for Research of Golden Eagle Japan was founded,

and observers with the ability of identifying Golden Eagles gathered although there were only a handful of such persons. Since then, the members of the Society across the nation have clarified the various aspects of the Golden Eagle on regional and national levels. Concerning reproductive success, the Society probably has covered most breeding pairs, at least two-thirds of the pairs in Japan every year, and accumulated the data about the success rates. Although the national averages of reproductive success were over 50% at the time of the foundation of the Society, the recent rates are around 20%. In my study area, it is not rare that the success of the year is less than 10%. Such changes are not peculiar to reproductive success. The decline in the number of breeding pairs, and the participation of younger birds to pair formation and the expansion of home range following the decline in the number of pairs are also found. Because of this, it is getting improper for only these 20 to 30 years to discuss the Golden Eagle based on the past data. In Japan, food shortage and decreases in suitable foraging habitats are assumed to be the major causes of a decline in the population and reproductive success in the species. This has been confirmed in some pairs in my study area. However, some conflicting data have also been obtained in my study area. Because of the changes showed above, it is believed that conserving the Golden Eagle is an urgent need in Japan. For conservation, I think that everchanging eagle behavior and habitat condition of each pair primarily need to be well understood. Golden Eagles are different in character and various abilities from each other as humans are. Therefore, a conservation program suitable for pairs in a region is not always appropriate to different pairs in a different region. “Careful and close observation” of each bird, though it is classic, is the important first step for eagle conservation. Such observation is absolutely necessary to correctly understand the most up-to-date circumstances surrounding each pair and consequently to promote the proper conservation of the species.

The Legge’s Hawk Eagle Nisaetus (Spizaetus)kelaarti has recently been split as a distinct species, distributed in SW India and on Sri Lanka. It is associated with primary evergreen forests and is threatened because of fragmentation and loss of habitat. The total population is estimated to less than 1000 pairs. The population in Western Ghats in India is divided in two subpopulations separated by the 32.2 km Palghat gap. We suggest that the conservation status would qualify as Vulnerable, because the largest subpopulation has 4mm) but not small particles (< 3mm) which may has implications for the further design of lead free rifle bullets.

RECENT ADVANCES IN THE BIOMEDICAL KNOWLEDGE OF THE ENDANGERED ARGENTINE CROWNED EAGLE (Harpyhaliaetus coronatus)

M. D. Saggese1 & A. Quaglia2 1 DVM MSc., PhD College of Veterinary Medicine - Western University of Health Sciences, Pomona, 91767, California [email protected] 2 Vet. Student Fundación de Historia Natural Félix de Azara. Departamento de Ciencias Naturales y Antropología. CEBBAD – Universidad Maimonides. Ciudad Autónoma de Buenos Aires. Argentina The crowned eagle (Harpyhalieatus coronatus), (Order Falconiformes, Family Accipitridae), inhabits central and northern Argentina, southern Brazil, Paraguay, Uruguay and eastern Bolivia. Internationally, this bird of prey is classified as endangered and is currently considered one of the most threatened raptors in Argentina. Information about its biology and natural history is limited. Like other large-sized birds of prey, crowned eagles require large territories in which to live and hunt their prey. Most reports about their breeding biology suggest that this eagle raises only one chick every two years. The reasons for crowned eagle scarcity are not well understood. Human persecution, reduction in the availability of prey, and loss of natural habitat are the major proposed causes for its continuing decline. Furthermore, collisions with vehicles and electrocution by power lines have been proposed as contributing factors to its endangerment. The potential role of macroparasites, microparasites and heavy metals in its decline and population dynamics has not been previously investigated. The aim of this presentation is to summarize biomedical work performed with captive and free-ranging crowned eagles in several areas of Argentina. Goals of our study were to collect baseline clinical reference values and investigate the consequences of their exposure to selected human, domestic animals and avian pathogens and metals in captive adults and free-ranging young crowned eagles. Understanding the role that macroparasites, microparasites and metals may play in the decline of these birds in the wild, their effect on ex-situ conservation programs and human and domestic animals may be essential to the effective management this eagle and for developing

conservation strategies. In order to achieve these goals the main specific aims of this study were to: 1) collect data on baseline physiological reference values, including hematology, serum biochemistry and plasma cholinesterase activity in captive adults and free-ranging nestling crowned eagles; 2) investigate their exposure to selected macroparasites, microparasites and metals, and 3) train argentine veterinarians, veterinary students, park rangers , biologists, and field conservation agents in the biomedical sampling of crowned eagles and other birds of prey. Samples were obtained from captive crowned eagles held at various zoos and rehabilitation centers in Mendoza, Buenos Aires and the Misiones provinces of Argentina. These birds are maintained in these facilities for educational purposes and are expected to be utilized in ex-situ conservation programs on location. Samples from free-ranging crowned eagles were obtained from nestlings in two different populations currently under intensive investigation in the Mendoza and La Pampa provinces. Specific results of these biomedical studies will be presented at the conference.

BEAK AND TALON GROWING RATE IN SELECTED MEDITERRANEAN EAGLE SPECIES: RESULTS FROM A YEAR ROUND STUDY.

J. M. Blanco1, L. McGough2, J. Rodriguez-Ramos1, U. Höfle3 and P. Cervera1 1. CERI-JCCM,Sevilleja del ala Jara, 45671 Toledo, Spain. 2. University of Oklahoma 3. IREC, UCLM, Ciudad Real, Spain Email: [email protected] The way beak and talons grow in birds of prey is poorly documented and not well understood. Thus, together with the growing rate, is of interest for the accurate interpretation of isotope studies. A total of 70 individuals from 5 different eagle species: Golden eagle (n= 14), Spanish Imperial eagle (n=22), Bonelli´s eagle (n=20), short toe eagle (n=6) and Booted eagle (n=8) were included in the present study. Small 0.5 mm depth marks were made 10 mm from the end of the cere, last finger scale and inner border of the nare, and in the frontal and lateral surfaces of the beak and talon of the finger IV using a sterile kirchner needle. Increase of that distance was measured one, three and twelve months after and average growing rate calculated. Growth observation and comparisons were made between location, measurements and species. There seem to be two main growing directions: towards the tip and up to the surface, with the latter appearing to be faster in the lateral surface of the talons, specially in Peregrines and Imperial eagles. Preliminary data shows that growth is much faster in younger animals. Growth along the surface is usually faster craneal Vs lateral and claw Vs beak. Growing rate is faster at the base of the beak compared to the tip. There are species specific differences in the growth rate. Average monthly beak (B) and talon (T), craneal (C) and lateral (L) growth were: BC 1,51, BL 1,06, TC 4,95, TL 4,55 for the Golden; BC 4,12, BL 3,28, TC 5,36 , TL 4,5 Spanish Imperial; BC , BL , TC , TL Bonelli´s; BC , BL , TC , TL , Short Toe and BC 1,03, BL 0,77 , TC 1,53 , TL 1,03 Booted eagles respectively. In certain species like the Short toed eagle, the growing rate is extremely slow compared to others. Although with some exceptions, growth corrected by size indicates that growth rates are generally faster in smaller Vs larger species within the same family and across them.

ASSESSMENT OF POTENTIAL PHYSIOLOGICAL CONSEQUENCES OF LEAD POISONING BY MRI AND PATHOLOGY: CAN THESE INFORM POPULATION LEVEL IMPACTS? O. Nicolas1 & P. Redig The Raptor Center, USA. Lead poisoning is a well recognized source of toxicosis in bald eagles (Haliaaetus leucocephalus). The preponderance of information suggests that spent lead ammunition embedded in the flesh of prey is a likely source. The Raptor Center (TRC) has been monitoring lead poisoning in bald eagles in the upper Midwest since 1970. Approximately 25% of the eagles received each year at TRC have clinical lead poisoning as a cause of admission. But over 70% have positive blood lead values that could be associated with the presenting injury. Lead (Pb) is a highly neurotoxic agent and the majority of the clinical signs these bald eagles present relate to the central nervous system (CNS). To date, there is no data regarding the distribution and appearance of lesions in the CNS. The Raptor Center conducted a preliminary study to evaluate the lesions occurring in the CNS due to lead poisoning. A clinical neurological examination, magnetic resonance imaging (MRI) and histopathology of the brain were conducted in 6 bald eagles with terminal lead intoxication. In all these birds, the histopathologic examination showed lesions in the brain consisting of necrosis, edema and/or hemorrhage. There was a correlation between the MRI and histopathology results. In most of the cases, the location and severity of the lesions were consistent with the neurological signs observed. This preliminary study shows the severity of the CNS lesions present in cases of terminal lead intoxication in bald eagles. The MRI has shown to be a useful assessment technique in cases of lead poisoning; further study is needed to demonstrate its usefulness as a prognostic tool. The application of the same protocol of study to subclinical lead intoxicated bald eagles would give us more specific information about the lead mechanisms of toxicity. The impact of lead poisoning on the total population of bald eagles, including both acute mortality and subclinical neurological and physiological impairment is not known.

E-mail: [email protected]; [email protected] EARTHMATTERS. ORG. P.O Box 15251, Gainesville, Fl 32604, USA El Proyecto de Conservación del Águila Harpía y de Grandes Rapaces en Venezuela, tiene como prioridad investigar sobre la biología, ecología y biomedicina; protección y recuperación de hábitats; implementación de programas de educación ambiental; ejecución de programas de vigilancia y control; rescate y rehabilitación de rapaces lesionadas; y actividades de cría y reproducción en cautiverio, con la finalidad de contribuir en el estudio y conservación integral de los falconiforme en diferentes ámbitos. Los programas de rehabilitación y cría en cautiverio, involucran diferentes manejos de reintroducción, transferencia y reforzamiento de poblaciones. Esto involucra ejemplares que provienen de vida silvestre a condiciones de cautiverio o viceversa, el intercambio entre zoológicos y la transferencia de especímenes de un hábitat silvestre a otro. Pero existe el riesgo de la introducción accidental de enfermedades infecciosas y parasitarias a las poblaciones de rapaces silvestres. En ocasiones, animales silvestres traslocados o liberados de una posterior rehabilitación, pueden presentar susceptibilidad a problemas de estrés originados por factores ambientales y de adaptabilidad a las condiciones del hábitat donde son reintroducidos, originando predisposición a sufrir enfermedades de origen etológico, nutricional, infeccioso, entre otros. La variabilidad genética de las poblaciones silvestres existentes y la presencia de un hábitat adecuado es proporcional a la reducción de las enfermedades que puedan afectar a las rapaces.

Contrariamente, en condiciones de cautiverio las leyes naturales pueden alterarse, donde altos niveles de estrés pueden ocasionar alteraciones en el sistema inmunológico de las rapaces, predisponiendo a la aparición de enfermedades. Un mal manejo biológico, zootécnico y/o veterinario puede originar índices elevados de movilidad y mortalidad, con escaso desarrollo en la condición física de los especímenes, favoreciendo la aparición de enfermedades. Las principales fuentes de rescate de aves de presa en Venezuela, provienen de: decomisos, donaciones, capturas, entregas voluntarias, entre otras; siendo las especies más frecuentes las pertenecientes a las familias Accipitridae y Falconidae. Estableciendo planes sanitarios y nutricionales adecuados en zoológicos y centros de rescate y rehabilitación, podemos reducir los índices de mortalidad y elevar las tasas de crecimiento y desarrollo de las rapaces, transformando la cría en cautiverio y la rehabilitación en una estrategia importante para garantizar la sobrevivencia de diferentes especies de rapaces.

California condor recovery….lessons learned

Michael Wallace, Ph. D. The institute for Conservation Research, Zoological Society of San Diego

Since 1987, when the last California condor was removed from the wild to the protective custody the Los Angeles and the San Diego Zoos, government and non- profit institutions have waged a pitched battle to not only prevent the species extinction through captive breeding but to build wild populations of condors to sustainable levels. The process required a better understanding and reduction of mortality factors such as lead poisoning, power line collisions ,trash Ingestion by condor nestlings and exposure to West Nile Virus. With additional program partners such as the Peregrine Fund, the Santa Barbara Zoo and the Oregon the program has expanded its support base and increased production of birds and areas for release to the wild. With a main goal of re-establishing populations in as many areas of their former range where suitable, releases began in 1992 at the Hopper Mountain National Wildlife Refuge in southern California, operated by the US Fish and Wildlife Service and were later followed by releases at the Ventana/ Big Sur site operated by the Ventana Wilderness Society In central California, the Vermilion cliffs north of the e Grand Canyon National Park in Arizona, operated by the Peregrine Fund, The Pinnacles National Monument in Central California operated by the National Park service and in Baja California, Mexico operated by the San Diego Zoo with partners in Mexicos, Instituto de Ecologia Nacional and Costa Salvaje. In 1987 there were 27 California condors in the world, Through these conservation efforts there now are 355 with 181 condors flying in the wild including 20 naturally fledged chicks.

(1) [email protected] (2) [email protected] En Agosto de 1991, se creó en Argentina el Proyecto de Conservación Cóndor Andino (Vultur gryphus) (PCCA). A través de su programa de incubación artificial y cría en aislamiento humano y gracias a la creación de un centro de rescate de ejemplares silvestres, ha logrado concretar la liberación de 91 ejemplares a lo largo de la cordillera de los Andes. Metodologías de trabajo: Centro de Incubación Artificial y Cría en Aislamiento Humano. Uno de los primeros pasos del proyecto fue poner en condiciones reproductivas a las parejas que se encuentran en cautiverio. Para ello se sumaron a los principales zoos en un programa de reproducción regional. Todos los pichones nacidos en el marco del proyecto son criados en aislamiento humano, en nurserys especialmente diseñadas, con la asistencia de títeres de látex que representan a sus padres. De esta manera se favorece el reconocimiento hacia su especie y se evita el imprintig con el ser humano. Ellos permanecerán en estas condiciones hasta completar su plumaje juvenil, pardo ocráceo, lo cual logran a partir de los seis meses de edad. A partir de ese momento estarán listos para ser incluidos en programas de liberación. Centro de Rescate del Cóndor Andino. En abril de 2002, hemos creado el Centro de Rescate del Cóndor Andino (CRCA), una herramienta de conservación que permite trabajar en el rescate y la rehabilitación de estas aves, con la finalidad de liberarlas en su ambiente natural o integrarlas a planes de conservación ex situ de esta especie. En el Centro de Rescate del Cóndor Andino contamos con un centro veteri-

nario y un área de rehabilitación en aislamiento humano para aquellos ejemplares silvestres que pueden ser incluidos en programas de liberación. En el caso de que los ejemplares puedan ser devueltos a su ambiente natural, se lleva a cabo la búsqueda del lugar de liberación, la cual va acompañada por una intensa campaña educativa en las zonas de influencia y un posterior seguimiento de los ejemplares que son liberados. Centro de Seguimiento y Estudios Poblacionales Los métodos tradicionales de seguimiento basados en el empleo de bandas alares de vinilo y radio telemetría, sumados al reciente desarrollo de transmisión satelital, han hecho posible entender su capacidad de vuelo, el uso que hacen del entorno natural y descubrir sus dormideros, lugares claves para la conservación de esta especie. Área de Educación y Difusión El PCCA cuenta con un centro de interpretación específico donde recibe millones de visitantes al año, quién a través de videos, fotos, charlas y demás medios educativos acceden a información concreta sobre los alcances y resultados del proyecto. Además, desarrollamos un programa de educación en las escuelas rurales y también de grandes ciudades, llegando con un mensaje claro de conservación. Se tarda tres años en devolver la libertad a un Cóndor, pero bastan unos segundos para quitarles la vida. Por eso un cambio cultural es imprescindible y son tan importantes los programas educativos y de difusión.

UPDATE AND CHALLENGES FOR CRITICALLY ENDANGERED GYPS VULTURES IN INDIA

C.G.R. Bowden1, R. Cuthbert1, R.E. Green1, V. Prakash2, N. Shah2 1. Royal Society for the Protection of Birds, The Lodge, Sandy, Bedfordshire SG19 2DL 2. Bombay Natural History Society, Hornbill House, Shaheed Bhagat Singh Road, Mumbai 400 001, India Three species of vultures (Gyps) endemic to South and South-East Asia are listed as Critically Endangered because of rapid population declines in the Indian subcontinent. The main cause of these declines is poisoning by the veterinary drug diclofenac, which is ingested by vultures that feed on the carcass of a domestic ungulate treated with the drug shortly before death. Remedial action in India to prevent the extinction of these species includes the removal of diclofenac from the vultures’ food supply and captive husbandry and breeding. Actions to reduce the risk from diclofenac include legislation preventing the manufacture of veterinary diclofenac, awareness campaigns for farmers’ organizations, pharmacists, veterinarians and government officials and safety testing to identify alternative drugs that do not harm vultures. Research has so far identified one drug, meloxicam, which does not harm vultures at the maximum likely exposure level. A monitoring program has estimated the proportion of domestic ungulate carcasses contaminated with diclofenac and how this has changed since the ban on manufacture of veterinary diclofenac. The availability and provenance of diclofenac offered for sale for veterinary use is being measured by visits to veterinary pharmacies. The prevalence of diclofenac in cattle carcasses has not yet fallen since the ban, and the drug remains widely available for use on livestock. Monitoring of vulture populations shows that they remain low. No species are recovering and one continues to decline rapidly. The breeding programme in India now holds over 220 founder birds of all three species combined, and at three separate centres. Breeding has so far been successfully achieved for two of these with encouraging signs that large-scale breeding will be achievable ready for future releases once diclofenac has been removed from the environment.

INTRODUCTORY LECTURE

ESTRATEGIA Y RESULTADOS DEL PROYECTO DE CONSERVACIÓN CÓNDOR ANDINO. N. L. Jácome 1 & V. Astore 2 Fundación BIOANDINA Argentina & Jardín Zoológico de la Ciudad de Buenos Aires. República de la India 3000 (1425) Buenos Aires, Argentina. [email protected] 2 [email protected] Durante miles de años, el Cóndor Andino, el ave voladora más grande del mundo, ha sido honrado por las comunidades originarias de Sudamérica, quienes lo consideran un nexo sagrado entre los hombres y Dios. Abundante en otro tiempo, este animal emblemático, eslabón simbólico con nuestro pasado cultural, se ha convertido hoy, lamentablemente, en un desafío de conservación. Por ello, en Agosto de 1991, se dio origen al Proyecto de Conservación Cóndor Andino (PCCA), realizado en el marco del Programa Binacional entre Chile y Argentina, un ejemplo de colaboración internacional que ha logrado reintroducir 91 ejemplares en todo Sudamérica. Su principal objetivo es asistir a la conservación de estas fabulosas aves y su majestuoso ecosistema, a todo lo largo de la cordillera, para asegurar la supervivencia de quien es considerado el Espíritu viviente de los Andes. El uso de radiotelemetría y transmisión satelital, asociado a intensos trabajos de campo, permitieron crear un GIS (Sistema de Información Geográfica) específico para esta especie en el marco del Programa Laboratorio de Investigación Registrado de Intergraph de la FBA. Además fue creado un software especial, llamado Decosat, un programa simulador de vuelo que ayuda a comprender mejor los patrones de sus desplazamientos. Gracias a esta moderna tecnología, es posible descubrir el uso que hacen del ambiente, sus dormideros, su capacidad de vuelo, preferencia de hábitat, entre otras cosas. Esta información orienta la toma de decisiones que hacen a la conservación de estas fabulosas aves y el equilibrio de su majestuoso ecosistema.

Gracias a la participación de comunidades originarias del Ande, quienes supieron honrar y convivir en armonía con esta especie durante miles de años, antes de cada liberación, se realizan ceremonias ancestrales. Ellos, son los encargados de poner un rezo en su lengua originaria, como un mensaje de respeto y veneración por toda la vida, para que el Espíritu de los Andes vuelva a ocupar su lugar.

Estrategia del Proyecto La estrategia del PCCA consiste en acciones de conservación ex situ e in situ, integradas en cuatro pilares principales: 1.

Centro de Incubación Artificial y Cría en Aislamiento Humano.

2.

Centro de Rescate del Cóndor Andino.

3.

Centro de Seguimiento y Estudios Poblacionales.

4.

Área de Educación y Difusión.

Resultados En diciembre de 1997 se concretó la liberación de cinco ejemplares en Valle Encantado, Patagonia, Argentina, y se estudió el vuelo de un ejemplar silvestre de la misma categoría de edad. Estos ejemplares fueron los primeros en el mundo en llevar en sus alas transmisores satelitales a energía solar. La puesta a punto de esta moderna tecnología permitió extender los conocimientos que se tenían de la especie. Posteriormente, en enero de 1999 y marzo del 2001, junto a la Fundación BIOANDINA Venezuela se logró realizar dos liberaciones en Venezuela y junto a la Fundación Bioandina de Venezuela, así 6 ejemplares fueron reintroducidos en un ambiente donde la especie había sido declarada extinta en 1965. Durante el año 1999, junto a la Fundación Zooprama de Bolivia, se concretó la liberación de 3 ejemplares de rescate en Tiraque, Corani, Bolivia.

En marzo de 2000, durante la Primer Reunión de Especialistas en Cóndor Andino, organizada por la Fundación Bioandina de Venezuela y la WWF (Fondo Mundial de la Naturaleza) en Venezuela, se ayudó a establecer una estrategia Sudamericana de conservación para esta especie, que destaca la necesidad de integrar los esfuerzos regionales que se llevan a cabo en todo el Ande. Siguiendo estos lineamientos, el Proyecto de Conservación del Cóndor Andino (PCCA), Argentina, y el Centro para las Aves Rapaces de Chile (CAR), a partir del año 2001, decidieron unir sus esfuerzos en un Programa Binacional de Conservación del Cóndor Andino (PBCCA). A partir de entonces, en el marco del PBCCA, fue posible realizar seis liberaciones más en Chile, liberando 22 ejemplares en total, junto a la Unión de Ornitólogos de dicho país y con la participación de instituciones internacionales. En Argentina, a partir de Diciembre de 2003, gracias a un esfuerzo internacional de conservación denominado “El Retorno del Cóndor al Mar” fue posible reintroducir la especie en su antigua área de distribución, la Costa Atlántica. Desde entonces, 26 ejemplares han sido liberados y gracias a intensos trabajos de campo y sofisticados sistemas de seguimiento satelital sabemos hoy que están ganando día a día mayor experiencia de vuelo, llegando a recorrer distancias mayores a 500 km desde su lugar de suelta, evidenciando con sus vuelos los lugares clave para la conservación de estas fabulosas aves en la costa. En Ecuador, en el año 2003, junto a la Dirección Nacional de Biodiversidad, Áreas Protegidas y Vida Silvestre dependiente del Ministerio del Ambiente, se participó en el desarrollo de una Estrategia Nacional para la Conservación de esta especie, la cual se encuentra en peligro crítico. En Colombia, gracias al apoyo de la Corporación Autónoma Regional de Boyacá, el Ministerio de Ambiente, Vivienda y Desarrollo Territorial y la Universidad Pedagógica y Tecnológica de dicho país, el PCCA ha participado de la liberación de tres ejemplares, en el Páramo de Siscunsi, liberados, el pasado 18 de noviembre de 2005, en el marco del Seminario Internacional de Actualización del Programa Nacional para la Conservación del Cóndor Andino y concertación del Plan de Acción 2006 – 2016 que tuvo lugar en la ciudad de Iza, Boyacá.

Gracias a estos 91 ejemplares liberados y a la tecnología satelital aplicada, fue posible monitorear 388.000 Km2 y comenzar a entender la capacidad de vuelo de la especie. Así se hizo evidente que los principales Parques Nacionales no cubren la necesidad de vuelo de estas aves y que una estrategia de conservación basada exclusivamente en ellos, no es efectiva. Pudimos comenzar a entender el uso que hacen del ambiente, el hábitat que prefieren y los patrones de vuelo que realizan, según su origen y categoría de edad. Pero, fundamentalmente, a partir de los datos nocturnos, pudimos descubrir las condoreras, lugares donde los cóndores se reúnen a dormir hasta en grupos de 124 individuos. Se tarda tres años en devolver la libertad a un Cóndor, pero bastan unos segundos para quitarles la vida. Por eso un cambio cultural es imprescindible y son tan importantes los programas educativos y de difusión.

ESTRATEGIA DE ACERCAMIENTO DE LA SOCIEDAD A DOS ESPECIES EMBLEMA (CÓNDOR ANDINO Y ÁGUILA HARPÍA) PARA SU CONSERVACIÓN

I. Muñoz Ron, R. Muñíz-López & P. Tufiño. Corporación SIMBIOE. Av. Patria 640 y Amazonas. Edf. Patria. Piso 13. Quito, Ecuador. [email protected], [email protected], [email protected] Ecuador, además de una enorme diversidad biológica y ecosistémica, posee una gran riqueza cultural. En total, existen 13 grupos indígenas en sus tres regiones naturales los cuales representan el 30 por ciento de la población, entre ellos: Awá, Chachi, Épera, Tsa´chila, Huaorani, Siona, Cofán, Secoya, Shuar, Zápara, Achuar y varios otros pueblos que pertenecen a la nacionalidad Kichwa de la región andina (Andes) y la Amazonia. El Programa de Conservación del Águila Harpía en Ecuador (PCAHE) tuvo sus comienzos en el año 2000. En la Amazonia inició su trabajo con los pueblos Zápara y Achuar de la Provincia de Pastaza, luego se amplió a los territorios de la comunidad Cofán de Zábalo, el pueblo Kichwa de Playas de Cuyabeno y Secoyas de San Pablo de Katetsiayá, todos localizados en la provincia de Sucumbíos, dentro de la Reserva de Producción Faunística Cuyabeno. En el Pacífico ecuatorial, el PCAHE trabaja con los pueblos afroecuatorianos de Playa de Oro y Winbí, y la comunidad de campesinos de Santa Rosa del Naranjal (Reserva Ecológica Cotacachi-Cayapas). Por otro lado, el Programa de Conservación del Cóndor Andino en Ecuador (PCCAE) tiene sus inicios en el año 2008 y su ámbito de acción ha sido básicamente con las comunidades y sociedad civil de la región centro norte de los Andes. Si bien es cierto, ambos proyectos se enfocan en la conservación de dos especies en particular, el contexto socio cultural así como ecosistémico es muy variado e inclusive en algunos casos, antagónicos. Pese a ello, la meta final para la conservación a largo plazo tanto del águila harpía como del cóndor, se fundamenta en rescatar y fortalecer los valores culturales y ancestrales de estas dos especies con los pueblos con quienes

comparten territorios. Lograrlo no resulta una tarea sencilla –y aún nos queda mucho camino por recorrer- pero gracias a él se han desarrollado cualidades peculiares en los grupos de técnicos involucrados. Actualmente, este proceso se sustenta en una estrategia cuyos cuatro puntos importantes son: a) el conocimiento de la realidad actual e histórica de los pueblos involucrados; b) el conocimiento del entorno natural de los mismos; c) una evaluación y capacitación del personal a desempeñarse dentro del proyecto en aspectos particularmente relacionados con “el saber ser y el saber estar” c) un proceso de acercamiento continuo y prolongado con las comunidades como un factor indispensable para el éxito.

THE HARPY EAGLE AS A PARTICIPATIVE TOOL TO IMPROVE MANAGEMENT AND CONSERVATION OF BIODIVERSITY

R. Muñiz López DirecciónPCAHE,SIMBIOE [email protected] / [email protected] The Harpy Eagle Conservation Program in Ecuador (PCAHE) begins in 2000 as a research project and as a tool to argue the value of the Ecuadorian Amazon heritage. At the beginning, our activities were developed in the province of Pastaza, within the territories of Achuar and Zapara ethnic groups, but later we expanded into the territories of the Cofan (also called A’i of the Aguarico River), Secoya, Cuyabeno Kichwa, lands of Afro-Ecuadorians in Esmeraldas province and farmers in the province of Imbabura. It is now also include groups as Siona and Shuar of the Cuyabeno River in the province of Sucumbios. The relationship with such a wide range of cultures focused the PCAHE goals towards conservation purposes, but taken in a holistic way, including these actions: • Research Tools: To monitor juveniles through PTT / GPS transmitters, direct observation of specimens, GIS to use it for habitat characterization and identification of potential breeding places, etc. • Education: Inserting the PCAHE environmental message in the curriculum of schools in each community and each province, to transmit an environmental message to adult audiences through traditional and festive and artistic activities, creation of opportunities for training, discussion and analysis around environmental and social aspects, etc.). • Social integration: Training and inclusion of biomonitors in the tasks of documentation, management decisions and participation in developing management plans for their areas. • Divulgation: Generation of graphic artwork and informative video, participation in events, etc.

INTRODUCTORY LECTURE

WHAT MAKES AN EAGLE TO BREED

C. Fentzloff Vormals Gründer und Direktor der DEUTSCHEN GREIFENWARTE Burg Guttenberg 1. Vorsitzender der EUROPEAN HALIAEETUS ASSOCIATION ( EHA) Europäische Gesellschaft für die Erhaltung bedrohter Vogelarte. e.V. Scheffelweg 3/1, 74206 Bad Wimpfen E-Mail:[email protected] www.claus-fentzloff.de My work as a teacher, in schools on behalf of the ministry of culture of Baden Wuerttemberg, on nature conservation led in 1961 to the foundation of the firs rehabilitation center for birds of prey and owls in Europe. Here, injured birds or orphaned juveniles were taken care off. After the first successful breeding had ocurred even with disabled non-releasable individuals the now called DEUTSCHE GREIFENWARTE was provieded with sea eagles and vultures from Zoos with the aim of initiating breeding programs, and received also eggs for incubation and chick raising. Special emphasis was on sea eagles and vultures. Natural breeding was preferred to artificial insemination because of clinal variation. In artificial incubation new ways were developped as for the first time a complete control of incubation and artificial management of the egg was applied and complete documentation of feeding intervals and growth curves/ breeding data was carried out during the first three to six weeks after hatching. Data on feeding intervals, and food intake has been documented of five individuals each of 35 different species. This includes specifically the white tailed sea eagle, Haliaeetus albicilla, the American Bald eagle, Haliaeetus leucocephalus, the palla’s sea eagle, Haliaeetus leucoryphus, African Fish eagle, Haliaeetus vociver, as well as the Hooded vulture, Aegypius monachus, Griffon vulture, Gyps fulvus, and Egyptian vulture, Neophron percnopterus. Some remarks on the relation of the Palm-nut vulture, Gypohierax angolensis, to other species are given at the end of the talk.

RESPONSIBILITY OF PUBLIC FACILITIES TO PARTAKE OF SUSTAINABLE USE OF RAPTORS

J. Parry-Jones International Centre for Birds of Prey, UK The use of birds of prey of many genera in ‘bird shows’ and demonstrations in zoos, specialist raptor centres and many other venues around the world has increased enormously over the last decade. However in many places there is little ethical thought about the origins of the birds, or the practices in collecting them. Often there is little or no consideration about long term sustainability, using Red List species, or investing in captive breeding programmes for the future. I suspect that few investigate how many birds are trapped and kept in poor conditions before exporting, how many do not survive before exporting, how many die soon after arriving, how many are sold with no legal requirement for their going to knowledgeable and responsible homes or how many are confiscated by governments and put in unsuitable establishments. The wholesale use of birds of prey in this way needs to be looked at rigorously. Zoos, bird of prey establishments and individuals should be required to have a written and provable sustainable plan to continue their ‘educational /entertainment’ programmes. Governments need to be strongly encouraged to look very hard at import applications, and should be asking about what long term plans there are for sustainability of birds. Selling on of wild imported birds needs to be regulated, Confiscated birds should only go to knowledgeable breeding programmes when they are rare and or endangered species.

INVESTIGATING CHANGES OF THE SAPROPHYTIC FLORA IN THE SALIVA OF FEMALE EAGLES IMMEDIATELY AFTER HATCHING

J. M. Blanco1, A. Knowless-Brown2, W. Voelker2, V. Arias1 and A. Donoghue2. 1. Centro de Estudios de Rapaces Ibéricas, CERI-JCCM. 2. SIA inc.Comanche Nation, Oklahoma.University of Arkansas Early after hatching parental eagle feeding behaviour characterized by selecting a minimal quantity of food, often clean muscle and blood from the prey, that parents mix with saliva using the upper beak and the tip of the tongue. Thus, in addition to the visual and auditory stimulus of the chick, immediately induce hypersalivation, a physiological reaction that seems to be designed to actually provide the chick with a diet close to 50% based on adult saliva during the crucial first few days of life. The length of this period varies with the individual, diet or age, but usually last between 3 and 10 days. Saliva has obvious benefits to the chick including facilitating ingestion, electrolitic balance and hydration. Saliva at that particular time is believed to be an important source of extra calcium, immunoglobulins and saprophytic flora, crucial for normal growth and immune protection. However, these aspects are poorly understood and therefore needed of specific research. A preliminary study was conducted to identify, quantify and bank normal flora present in the saliva of Golden eagle females at that particular time compared to results out of the season. Saliva from three imprinted female Golden eagles was taken twice during the early rearing period and twice out of it. Special care was taken to collect clean samples, which becomes extremely difficult as it get easily contaminated with food. Samples were cultured following standard microbiological procedures for identification and quantification of the isolated strains. Results indicate that E.coli (310-452 ufc/100ul) is the organism present in highest concentration in 100% of the early samples. However, concentrations of this organism got reduced to more than one third in the late samples in all the cases examined. Opposite to that, other isolated secondary species like Kocuria varians rosea (14-54 ufc/100ul), Kocuria kristinae (47-58 ufc/100ul) or Staphylococus xylosus (100-130 ufc/100ul) experience a exponential, medium and small increase in their concentration respectively

during the same period. Some spp sporadically isolated included Pantoea spp (236-325 ufc/100ul), staphylococus aureus (15-23 ufc/100ul) and the potentially pathological Hafnia alvei (261ufc/100ul). Results show a significant average (34,2%) reduction in the concentration of organisms present in the saliva during the early rearing phase compared to results from samples out of the breeding season, thus in correlation with an increase in calcium and pH which characterize saliva during that period. Preliminary results and potential significance of the strains isolated are analysed and hypothesis raised.

INVESTIGATING EMBRYONIC MORTALITY OF INFECTIOUS AND PERSISTENT CONTAMINANTS ETIOLOGY

J. M. Blanco1, U. Höfle2 & L. Palma3 1. Centro de Estudios de Rapaces Ibéricas (CERI-JCCM), Sevilleja de la Jara, 45671 Toledo, Spain 2. Instituto de Investigación en Recursos Cinegéticos IREC, Ronda de Toledo s/n 13005 Ciudad Real, Spain. 3. Universidade do Algarve, Faro, Portugal Embryonic and neonatal mortality of diverse etiology are usually underlying causes for decreased eagle productivity. Thus mainly due to obvious difficulties in accurate monitoring of clutch size, hatching success and early death without disturbing the pair. In contrast, study of addled eggs recovered at the time of nestling radio tagging or at the end of the breeding season becomes a crucial source of information. During the last 16 years forensic investigation and analysis was carried out on a total of 100 addled eggs from Golden (n= 10), Spanish Imperial (n= 27), Bonelli´s eagles (n= 48 ) and Osprey (n= 15). From the eggs examined, 48% were infertile, the remaining contained embryos dead during the first (28%), second (6%) and third (18%) third of the incubation period. Late deaths, including dead in shell, were mostly due to bacterial diseases (45,3%), with Salmonella spp as the most frequently isolated. However, accidental cooling due to different reasons including nest falling by storms and parent abandon because or severe disturbance or poisoning were also extensively documented. Occasionally malpositions, with head between legs and head under wing as the most frequent, were also found to be responsible for late dead. In contrast, investigation of early and mid term deaths proved much difficult due to the severe autolysis that complicates, when not avoid, isolation of the microorganisms potentially responsible as well as documenting histopathological findings for accurate diagnosis and interpretation. Some early deaths have been correlated to parental lack of incubation experience, particularly male failure to take incubation turn and proper seating due to suboptimal pair bond, which leads to egg cooling. A considerable number of early deaths were related to egg breakage during the first third of the incubation period due to abnormal eggshell ultrastructure which increase fragility. Thus were usually related to combinations of not necessarily high levels of DDE and PCBs, or high levels of mercury.
