WATTS Center for Conservation Biology, College of William & Mary, Williamsburg, VA 23187 USA and Virginia Commonwealth University, Williamsburg, VA 23284 USA ABSTRACT.—Electrocution is a widespread conservation problem for birds of prey that has received little attention in the Neotropics. Here we present electrocution records involving the endangered Chaco Eagle (Buteogallus coronatus) in central Argentina, and we provide information on the power pole structural characteristics associated with electrocutions. Nine Chaco Eagles were recorded electrocuted during the period 2012–2019 over an area of 9000 km2. Chaco Eagles were found electrocuted in association with five types of power poles, but more than half the electrocutions (55%) were on poles made of steel-reinforced concrete and with jumper wires above the crossarms. With the addition of four previous electrocution reports in this region during the same time period, the annual rate of Chaco Eagle electrocutions was similar to the rate of mortality by other human-related factors such as direct persecution. -
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). -

Diploid number ranges between 2n = 66 and 2n = 68. Only one species, L. albicollis had its karyotype analyzed by molecular cytogenetics. The aim of this study was to present chromosomal analysis of three species of Buteoninae: Rupornis magnirostris, Asturina nitida and Buteogallus meridionallis using fluorescence in situ hybridization (FISH) experiments with telomeric and rDNA probes, as well as whole chromosome probes derived from Gallus gallus and Leucopternis albicollis. The three species analyzed herein showed similar karyotypes, with 2n = 68. Telomeric probes showed some interstitial telomeric sequences, which could be resulted by fusion processes occurred in the chromosomal evolution of the group, including the one found in the tassociation GGA1p/GGA6. -
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).

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. -

Sun Parakeet Birding Tour
Leon Moore Nature Experience – Sun Parakeet Birding Tour Guyana is a small English-speaking country located on the Atlantic Coast of South America, east of Venezuela and west of Suriname. Deserving of its reputation as one of the top birding and wildlife destinations in South America, Guyana’s pristine habitats stretch from the protected shell beach and mangrove forest along the northern coast, across the vast untouched rainforest of the interior, to the wide open savannah of the Rupununi in the south. Guyana hosts more than 850 different species of birds covering over 70 families. Perhaps the biggest attraction is the 45+ Guianan Shield endemic species that are more easily seen here than any other country in South America. These sought-after near-endemic species include everything from the ridiculous to the sublime - from the outrageous Capuchinbird with a bizarre voice unlike any other avian species to the unbelievably stunning Guianan Cock-of-the-Rock. While the majestic Harpy Eagle is on everyone’s “must-see” list, other species are not to be overlooked, such as Rufous-throated, White-plumed and Wing-barred Antbirds, Gray-winged Trumpeter, Rufous-winged Ground Cuckoo, Blood-colored Woodpecker, Rufous Crab-Hawk, Guianan Red-Cotinga, White-winged Potoo, Black Curassow, Sun Parakeet, Red Siskin, Rio-Branco Antbird, and the Dusky Purpletuft. These are just a few of the many spectacular birding highlights that can be seen in this amazing country. Not only is Guyana a remarkable birding destination, but it also offers tourists the opportunity to observe many other unique fauna. The elusive Jaguar can sometimes be seen along trails and roadways. -
Mimicry in Birds of Prey Published 4 April 2013
Brazilian raptors (Online publications) www.avesderapinabrasil.com Mimicry in birds of prey Published 4 April 2013 Juvenile Grey-headed Kite (Leptodon cayanensis) with a plumage pattern that imitates almost perfectly an Ornate Hawk-Eagle (Spizaetus ornatus). Belterra (Pará), March 2013. Photo: Eleonora Pinheiro Willian Menq 1 Email: [email protected] Translated by Johan Ingels. Mimicry in birds of prey is impressive although uncommon. Some predators use mimicry as a hunting strategy. This is the case with the Zone-tailed Hawk (Buteo albonotatus) which imitates the inoffensive vultures of the genus Cathartes to approach prey (Peckhamian mimicry). But a mimic that mimics another more dangerous species, seems to be the most common type of mimicry among hawks in Brazil. So, the Rufous-thighed Kite (Harpagus diodon) which has a predominantly insectivorous diet mimics a Bicoloured Hawk (Accipiter bicolor) which mostly hunts birds. Other species of raptors only utilise mimicry as a juvenile, which is the case with the Grey- bellied Hawk (Accipiter poliogaster) and the Grey-headed Kite (Leptodon cayanensis). The juvenile plumage of the Grey-bellied Hawk is very similar to the adult plumage of the Ornate Hawk-Eagle (Spizaetus ornatus), possibly as a defense against other hawks and large primates that could prey on its nest. The juvenile Grey-headed Kites are highly polymorphic, presenting diverse plumage patterns. There are totally white individuals that mimic the Black-and-white Hawk-Eagle (Spizaetus melanoleucus), others are almost completely black resembling a Black Hawk-Eagle (Spizaetus tyrannus), and there are some rare intermediate forms that have little 1 MENQ, W.

Behavioral Notes and Nesting of the Black Solitary Eagle (Buteogallus Solitarius) in Belize
Transactions of the Illinois State Academy of Science received 8/11/15 (2016) Volume 109, pp. 29-33 accepted 4/15/16 Behavioral Notes and Nesting of the Black Solitary Eagle (Buteogallus solitarius) in Belize 1,3Stacia A. 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.
