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. -
A Case of Cooperative Hunting by a Pair of Northern Goshawks

A case of cooperative hunting by a pair of northern goshawks. Acta zool. cracov., 63(2): 21-22. Abstract. Cooperative hunting is a rare strategy in raptors, although it has been widely described in Falconidae and in some species of Accipitridae. Records about synchronous hunting in the member of the genus Accipiter are occasional. Here we describe a case of the cooperative hunting of two northern goshawks, A. gentilis, of a pigeon, Columba sp., observed in southern Poland in 2020. This exemplary behavior could be either exceptional, or cooperative hunting is an overlooked phenomenon in goshawk biology. Key words: Accipiter gentilis, Accipitridae, Columba, tandem hunting, prey. *£ukasz KAJTOCH, Bart³omiej KUSAL, Institute of Systematics and Evolution of Animals Polish Academy of Sciences, S³awkowska 17, 31-016, Kraków, Poland.

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.

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).

The breeding biology of the Long-legged Buzzard ( Buteo rufinus) was studied in the Evros area, north-eastern Greece in 1989, 1990, 1992 and 1993. The mean number of young fledged per pair per year was similar between years with an overall average of 0.93 (1.58 per successful pair). Of ten home range variables examined, the num ber of alternative nest sites and the extent of forest free areas in home ranges were significant predictors of nest ling productivity. Aggressive interactions were observed with 18 bird species (of which 12 were raptors), most commonly with the Buzzard {Buteo buteo). Such interactions declined during the course of the season. Prey pro visioning to nestlings was greatest in the morning and late in the afternoon declining in the intermediate period. Key words: Buteo rufinus, reproduction, behaviour, Greece.

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. -

We studied various aspects regarding migration behavior of the Common Buzzard for two subspecies (B. b. buteo and B. b. vulpinus) transiting the region which overlaps with the Western Black Sea Corridor. Using vantage points set across Dobruja we managed to count 2,662 individuals. We highlighted the seasonal and diurnal peak passage, flight directions and height of flight for each season. Our results suggest that 57% of the counted individuals belongs to long-distance migrant Steppe Buzzard - B. b. vulpinus. The peek passage period in autumn migration was reached between the 26th of September to the 6th of October, while for the spring migration peek passage remained uncertain. The main autumn passage direction was from N to S, and NNW to SSE but also from NE to SW. For spring passage the main direction was from S to N but also from ESE to WNW. -
On the Uniqueness of Color Patterns in Raptor Feathers
J. Raptor Res. 43(1):11–26 E 2009 The Raptor Research Foundation, Inc. ON THE UNIQUENESS OF COLOR PATTERNS IN RAPTOR FEATHERS DAVID H. ELLIS1 USGS Southwest Biological Science Center, Sonoran Desert Research Station, 1110 E. South Campus Drive, Room 119, University of Arizona, Tucson, AZ 85721 U.S.A. ABSTRACT.—For this study, I compared sequentially molted feathers for a few captive raptors from year to year and symmetrically matched feathers (left/right pairs) for many raptors to see if color patterns of sequential feather pairs were identical or if symmetrical pairs were mirror-image identical. Feather pairs were found to be identical only when without color pattern (e.g., the all-white rectrices of Bald Eagles [Haliaeetus leucocephalus]). Complex patterns were not closely matched, but some simple patterns were sometimes closely matched, although not identical. Previous claims that complex color patterns in feather pairs are fingerprint-identical (and therefore that molted feathers from wild raptors can be used to identify breeding adults from year to year with certainty) were found to be untrue: each feather is unique. Although it is unwise to be certain of bird of origin using normal feathers, abnormal feathers can often be so used.

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.

Winter Presence of Long-Legged Buzzard (Buteo Rufinus) in Moldova (Romania)
Travaux du Muséum National d’Histoire Naturelle © 28 décembre «Grigore Antipa» Vol. LV (2) pp. 285–290 2012 DOI: 10.2478/v10191-012-0018-6 WINTER PRESENCE OF LONG-LEGGED BUZZARD (BUTEO RUFINUS) IN MOLDOVA (ROMANIA) EMANUEL ȘTEFAN BALTAG, VIOREL POCORA, CONSTANTIN ION, LUCIAN SFÎCĂ Abstract. Long-legged Buzzard (Buteo rufinus) is a medium sized bird of prey which is known as a breeding species for Romania. In the last years it started to become a common wintering presence in the south-eastern part of Romania (Dobrogea) but it was also recorded in the more northern areas (Moldova) during the cold season. Its presence in Moldova, during the winter period, was recorded in large river valleys, with agricultural lands or grasslands and with trees or timber poles, which are used for perching. Long-legged Buzzard is a new presence for Moldavian winter seasons and it could be observed only in warm periods of winter, when the daily mean temperature is above 0°C. The wintering places are maintained not only for all winter period, but also for the next years. This behaviour could be explained by its territorial fidelity, which was recorded also in other European buzzard species during the winter period. Résumé. Buse féroce (Buteo rufinus) est un oiseau de taille moyenne de proie qui est connu comme une espèce nicheuse pour la Roumanie. Dans les dernières années, il est devenu une présence commune au cours de l’hiver au sud-est de la Roumanie (Dobroudja), mais il était également enregistré dans les régions du Nord (Moldavie) pendant la saison froide.
