W. Miller in litt. 2000]), Honduras, Nicaragua, Costa Rica, Panama (including four birds introduced in 1998 [Bell 1998]), Colombia, Venezuela, Guyana, Suriname, French Guiana (perhaps 200-400 pairs [Thiollay 1985b]), Ecuador, Peru, Bolivia, Brazil, Paraguay and north-east Argentina (Misiones, but formerly Formosa, Salta and Jujuy [Chebez 1994, Chebez et al. 1995, Vargas et al. 2006]). It is thought to be locally or regionally extinct in large parts of its former range, notably most of central and north Central America and possibly Rio Grande do Sul, Brazil (Bierregaard 1994a, Bierregaard et al. 1995), but recent records suggest that the population in the southern Atlantic forests may be migratory (Galetti et al. 1997b).

Panjabi in litt. 2008), thus it is placed in the band 20,000-49,999 individuals here. Trend Justification This species is suspected to lose 27.6-45.5% of suitable habitat within its distribution over three generations (56 years) based on a model of Amazonian deforestation (Soares-Filho et al. 2006, Bird et al. 2011). However, losses outside Amazonia are judged to be likely to be lower (A. Lees in litt. 2011), so the species is therefore suspected to decline by 25-29% over three generations. Current Population Trend: Decreasing Habitat and Ecology (see Appendix for additional information) It occurs in uninterrupted expanses of lowland tropical forest (typically below 900 m but locally to 2,000 m), but will nest where high-grade forestry has been practised, and use forest patches within a pasture/forest mosaic for hunting (Bierregaard 1994a, Parker et al. 1996; Álvarez-Cordero 1996, Muñiz- López 2016). Nests have been reported only 3 km apart in Panama and Guyana (Bierregaard 1994a). Systems: Terrestrial Threats (see Appendix for additional information) Although still reasonably common in the Amazonian forests of Venezuela, Colombia, Ecuador, Peru, Bolivia and Brazil (Álvarez-Cordero 1996, Vargas et al. 2006, Muñiz-Lopez 2008), it will only survive in the long term if the escalating rates of forest loss, fragmentation and degradation in the region is brought under control and a network of inviolate reserves established (Malingreau and Tucker 1988, Bierregaard 1994a, A. Lees in litt. 2016). Low overall population densities and slow reproductive rates make shooting the most significant threat over its entire range (Bierregaard 1994a, Bierregaard et al. 1995, Vargas et al. 2006, Muñiz López 2016). It could perhaps survive in disturbed forests or even forest mosaics if its large size and boldness in the face of humans did not make it an irresistible target for hunters (Bierregaard 1994a, Bierregaard et al. 1995, Álvarez Cordero 1996, Muñiz-López 2016). It presumably also suffers from competition with humans for prey (Galetti et al. 1997b, Muñiz-López 2016). Predation of small livestock leading to human-wildlife competition may be a very significant source of mortality (Trinca et al. 1998). Hunting and loss of large emergent trees through selective logging have contributed to its local extinction along deforestation frontiers (Moura et al. 2014). Conservation Actions (see Appendix for additional information) Conservation Actions Underway CITES Appendix I and II. Reintroductions have taken place in Belize and Panama (Matola 2004, Muela and Curti 2005). In Ecuador a programme is underway to research the species's status, ecology, movements and threats.Conservation Actions Proposed Work with local communities to reduce hunting. Stengthen network of protected areas to include core remaining areas of habitat, and establish a captive breeding population to support future reintroduction and supplementation efforts. Clarify its precise ecological requirements and its ability to persist in fragmented and altered habitats. © The IUCN Red List of Threatened Species: Harpia harpyja – published in 2017. 4 http://dx.doi.org/10.2305/IUCN.UK.2017-3.RLTS.T22695998A117357127.en Credits Assessor(s): BirdLife International Reviewer(s): Butchart, S. & Symes, A.

Helbig'^*, Annett Kocum'^, Ingrid Seibold^, Michael J. Braun^ '^ Institute of Zoology, University of Greifswald, Vogelwarte Hiddensee, D-18565 Kloster, Germany Department of Zoology, National Museum of Natural History, Smithsonian Institution, 4210 Silver Hill Rd., Suitland, MD 20746, USA Received 19 March 2004; revised 21 September 2004 Available online 24 December 2004 Abstract The phylogeny of the tribe Aquilini (eagles with fully feathered tarsi) was investigated using 4.2 kb of DNA sequence of one mito- chondrial (cyt b) and three nuclear loci (RAG-1 coding region, LDH intron 3, and adenylate-kinase intron 5). Phylogenetic signal was highly congruent and complementary between mtDNA and nuclear genes. In addition to single-nucleotide variation, shared deletions in nuclear introns supported one basal and two peripheral clades within the Aquilini. Monophyly of the Aquilini relative to other birds of prey was confirmed. However, all polytypic genera within the tribe, Spizaetus, Aquila, Hieraaetus, turned out to be non-monophyletic. Old World Spizaetus and Stephanoaetus together appear to be the sister group of the rest of the Aquilini. Spiza- stur melanoleucus and Oroaetus isidori axe nested among the New World Spizaetus species and should be merged with that genus. The Old World 'Spizaetus' species should be assigned to the genus Nisaetus (Hodgson, 1836). The sister species of the two spotted eagles (Aquila clanga and Aquila pomarina) is the African Long-crested Eagle (Lophaetus occipitalis).

  • Taphonomic Aspects of Crowned Hawk-Eagle Predation on Monkeys

University, Ann Arbor, MI 48109-1063, USA c Department of Anthropology, University of Michigan, 500 South State Street, Ann Arbor, MI 48109-1382, USA Received 24 January 2002; accepted 11 November 2002 Abstract This study provides a taphonomic analysis of prey accumulations of crowned hawk-eagles (Stephanoaetus coronatus) from Ngogo, Kibale National Park, Uganda, collected over 37 months from below nests of two eagle pairs. Crowned hawk-eagles are powerful predators capable of killing animals much larger than themselves, and are significant predators of cercopithecoid monkeys in forest habitats throughout sub-Saharan Africa. At Ngogo, 81% of the individuals in the kill sample are monkeys. Redtail monkeys (Cercopithecus ascanius) are particularly well represented in the sample, making up 66% of monkeys identified to species. Despite an impressive killing apparatus, crowned hawk-eagles are fastidious eaters that inflict far less damage to bone than mammalian predators. Examination of skeletal material from the Ngogo kill sample reveals that crania, hindlimb elements, and scapulae survive predation better than do other bones. Crania of adults are typically complete and accompanied by mandibles, while crania of young individuals are usually dissociated from mandibles and lack basicrania and faces. Long bones are often whole or show minimal damage. Thin bones, such as crania and innominates, are marked by numerous nicks, punctures, and “can-opener” perforations.

    Belize Harpy Eagle Restoration Program - The Belize Zoo Belize Harpy Eagle Restoration Program THE BELIZE HARPY EAGLE RESTORATION PROGRAM (BHERP) WORKING TO EMPOWER THE MESOAMERICA BIOLOGICAL CORRIDOR, MBC Introduction: BHERP is enjoying a positive and successful profile at this writing, and I am pleased to share the progress that the Program has made with all of our readers. While there are many players and stakeholders in BHERP, it is necessary to recognize the professional approach the program has benefited from by The Peregrine Fund, TPF. Those of us in Belize monitoring the released Harpy Eagles, carrying out Environmental Education on behalf of these raptors, and providing basic resources, are following the lead from TPF, and it can rightfully be assumed that their 30 years of experience to conserve wild populations of birds of prey, is now benefiting Belize through BHERP. The Peregrine Falcon and the Mauritius Kestrel are two species of birds of prey which have been saved from extinction by captive breeding and re-introduction efforts from TPF. Their diligent efforts on behalf of restoring the California Condor back into its former range are recognized throughout the world. We hope that 1 / 7 Belize Harpy Eagle Restoration Program - The Belize Zoo within the upcoming few years, The Harpy Eagle, brought back to the Meso-America Biological Corridor, MBC can be added to their list of success stories. The below update indicates that we are headed in a direction of successful restoration of the Harpy Eagle back into the MBC, with Belize hosting the forest landscape for project initiation. A.

A caça arbitrária de harpias não parece ser muito freqüente, mas pode ter um impacto relativamente grande sobre as populações locais, considerando sua baixa densidade, e também para o ecossistema, por causa do papel ecológico da espécie, como um predador de topo.

  • Estimations Relative to Birds of Prey in Captivity in the United States of America
    ESTIMATIONS RELATIVE TO BIRDS OF PREY IN CAPTIVITY IN THE UNITED STATES OF AMERICA by Roger Thacker Department of Animal Laboratories The Ohio State University Columbus, Ohio 43210 Introduction. Counts relating to birds of prey in captivity have been accomplished in some European countries; how- ever, to the knowledge of this author no such information is available in the United States of America. The following paper consistsof data related to this subject collected during 1969-1970 from surveys carried out in many different direc- tions within this country. Methods. In an attempt to obtain as clear a picture as pos- sible, counts were divided into specific areas: Research, Zoo- logical, Falconry, and Pet Holders. It became obvious as the project advanced that in some casesthere was overlap from one area to another; an example of this being a falconer working with a bird both for falconry and research purposes. In some instances such as this, the author has used his own judgment in placing birds in specific categories; in other in- stances received information has been used for this purpose. It has also become clear during this project that a count of "pets" is very difficult to obtain. Lack of interest, non-coop- eration, or no available information from animal sales firms makes the task very difficult, as unfortunately, to obtain a clear dispersal picture it is from such sourcesthat informa- tion must be gleaned. However, data related to the importa- tion of birds' of prey as recorded by the Bureau of Sport Fisheries and Wildlife is included, and it is felt some observa- tions can be made from these figures.

During fieldwork in RESEX Médio-Juruá reserve, in Amazonas, Brazil, in June-August 2009, images were captured by remote camera traps of an Ornate Hawk-Eagle interacting with a cattle femur, indicating possible scavenging behavior. Additionally, apparent investigatory behavior was also recorded in Slate-colored Hawk (Buteogallus schistaceus), a previously unrecorded behavior for the species.
