BREEDING ECOLOGY OF THE CRESTED SERPENT EAGLE Spilornis cheela (LATHAM, 1790) (AVES: ACCIPITRIFORMES: ACCIPITRIDAE) IN KOLLI HILLS, TAMIL NADU, INDIA Sectional Editor: Sujan Henkanaththegedara Submitted: 24 January 2012, Accepted: 27 June 2012 Varadarajan Gokula Post Graduate & Research Department of Zoology, National College, Tiruchirappalli 620001, Tamil Nadu, India; E-mail: [email protected] Abstract The breeding ecology of the crested serpent eagle (Spilornis cheela), focusing on nest-site selection, food habits, and perch-site preference, was studied in the Kolli Hills of Tamil Nadu, India, from May 2005 to May 2010. Thirty-two active nests were located, with nest-site details collected from 27 nests that were accessible. The crested serpent eagle did not construct new nests, but did renew or alter old nests, mainly in December. Both sexes were involved in the nest renewal activities. The clutch size was one, the mean incubation period was 41.5 days, and the mean fledging period was 64.5 days. Nests were found largely along riverine patches. The results indicate the mature and less disturbed riverine forests with large sized trees are critical for the breeding and conservation of this species. The food habits of the eagle were known from prey items brought into the nest by the adult to feed the chick and prey items fed on by the adult. In total, 173 feeding observations were made and the prey items belonged to 17 species of vertebrates. The crested serpent eagle largely preferred reptiles, which accounted for 74% of their diet, followed by birds, which accounted for 18% of their diet. -
Disaggregation of Bird Families Listed on Cms Appendix Ii
Convention on the Conservation of Migratory Species of Wild Animals 2nd Meeting of the Sessional Committee of the CMS Scientific Council (ScC-SC2) Bonn, Germany, 10 – 14 July 2017 UNEP/CMS/ScC-SC2/Inf.3 DISAGGREGATION OF BIRD FAMILIES LISTED ON CMS APPENDIX II (Prepared by the Appointed Councillors for Birds) Summary: The first meeting of the Sessional Committee of the Scientific Council identified the adoption of a new standard reference for avian taxonomy as an opportunity to disaggregate the higher-level taxa listed on Appendix II and to identify those that are considered to be migratory species and that have an unfavourable conservation status. The current paper presents an initial analysis of the higher-level disaggregation using the Handbook of the Birds of the World/BirdLife International Illustrated Checklist of the Birds of the World Volumes 1 and 2 taxonomy, and identifies the challenges in completing the analysis to identify all of the migratory species and the corresponding Range States. The document has been prepared by the COP Appointed Scientific Councilors for Birds. This is a supplementary paper to COP document UNEP/CMS/COP12/Doc.25.3 on Taxonomy and Nomenclature UNEP/CMS/ScC-Sc2/Inf.3 DISAGGREGATION OF BIRD FAMILIES LISTED ON CMS APPENDIX II 1. Through Resolution 11.19, the Conference of Parties adopted as the standard reference for bird taxonomy and nomenclature for Non-Passerine species the Handbook of the Birds of the World/BirdLife International Illustrated Checklist of the Birds of the World, Volume 1: Non-Passerines, by Josep del Hoyo and Nigel J.

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

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. -
Field Identification of the Field Identification of the Field
TOPICS IN IDENTIFICATION he Solitary Eagle ( Harpyhaliaetus solitarius ) is a large raptor that is closely related and similar in adult and immature plum- Tages to the black-hawks in the genus Buteogallus (Lerner and Mindell 2005). It is a rare and very local resident in a variety of wet and dry forested hills and highlands from northern Argentina to northern Mexico (del Hoyo et al. 1994, Ferguson-Lees and Christie 2001). The species has been collected in Mexico not far from the Texas border (see Discussion, pp. 72 –73), so it is possible that it has occurred in the ABA Area. The handful of specimens and nest records of this eagle are from 700 to 2,000 meters above sea level (Brown and Amadon 1968).

Belize Harpy Eagle Restoration Program - the Belize Zoo
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. Entre as possíveis estratégias mitigadoras, sugere-se utilizar a harpia como espécie bandeira para o desenvolvimento de programas de conservação na região.

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. -

Novy and 2Robb D. Van Putte 1Southern Illinois University Edwardsville, Edwardsville IL 62026 2McKendree University, 701 College Road, Lebanon IL 62254 3Corresponding author: [email protected] ABSTRACT Behavioral observations of the first recorded Black Solitary Eagle (Buteogallus solitarius) nest with a two-month-old nestling in the Cayo District, Belize were made from 7 – 30 June 2011. The nest was in a fork of the main trunk of a Nicaraguan Pine (Pinus oocarpa) with an eastern slope exposure at ~670 m elevation. The nesting area was ecotonal submontane pine forest overlooking deep valleys of broadleaf forest. Observations suggest the species forages for snakes (Genera: Spilotes, Drymobius and Dryadophis) in broadleaf forest habitat at elevations ≤ 400 m. Black Solitary Eagles relied on static soaring to deliver prey to the nest, following an indirect route over mountain contours. Of the observed flights (N=10), soaring averaged 4.65 min, while flapping flight averaged 0.08 min. Soaring duration (N=6) averaged 6.75 min with carried snake prey, but decreased to 2.00 min without prey (N=3). Our notes offer new insights on the habitat use, flight styles and patterns, and other behaviors of this poorly known Nearctic-Neotropical raptor.
