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.

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. -
Raptor Trade in Kuwait Bird Market

[email protected] Summary This article documents the illegal raptor trade in Kuwait Bird Market for the period from 1st January Fig. 1: Kuwait bird market 2010 to 30th May 2010. Seventeen species of raptors were offered for sale of which three are METHODS listed in the IUCN red list. The weekend in Kuwait is Friday and Saturday. Weekly visits were made to the Bird Market on Introduction weekends from 1st January to 30th May 2010. Only There have been a number of recent assessments of the trade in wild birds in the Middle East, one weekend was missed in January. Visits were (Bachmann 2010, Stanton 2010) and our report sheds some light on this illegal activity in Kuwait. Our brief; scanning the market from one end to the other, aim was to address this issue for further bird conservation. sometimes more time was spent. Thirty two visits were paid to the Bird Market. The The Bird Market is situated in Al-Rai Area. It started near to the old Sheep Market and developed into authors estimate that on average they have recorded a weekend market run by pet owners who sell pigeons, chickens and cage birds. The municipality only less than 25% of what had been sold in the intervened and made a building to include licensed pet shops and a covered open area used by pet market and actual numbers may be much higher. -

Wave Moult of the Primaries in Accipitrid Raptors, and Its Use in Ageing Immatures
Chancellor, R. D. & B.-U. Meyburg eds. 2004 Raptors Worldwide WWGBP/MME Wave Moult of the Primaries in Accipitrid raptors, and its use in ageing immatures William S. Clark ABSTRACT Stresemann & Stresemann (1966) described wave moult in the primary remiges ('Staffelmauser' in German; also translated as 'step-wise moult') for some families of birds but not for Acccipitrid raptors, even though many of the species in this family (especially the larger ones) show it. Primaries of Accipitrid raptors are replaced from Pl (inner) sequentially outward. Waves are formed when not all of the ten primaries are replaced in any annual moult cycle. In the next annual cycle, moult begins anew at Pl as well as continuing with the next feather from where it left off in the last cycle. Two or three, occasionally four, wave fronts of new primaries can be seen in the primaries of some raptors, especially larger ones, e.g., eagles. Knowledge and understanding of wave moult can ascertain the ages of immature raptors in those species that take three or four years to attain adult plumage, as these species typically do not replace all of the primaries in any moult cycle. Juvenile eagles show all primaries the same age. Second plumage eagles show two ages of primaries, newer inner ones and older retained juvenile outer ones. Third plumage eagles show two waves, with the first wave proceeding to P8, P9, or PIO, and the second to P3, P4, P5, or P6. Fourth plumage eagles usually show new outer PlO from the first wave, new P5 to P7 from the second wave, and new Pl to P3 from the most recent wave. -

Phylogeny, Historical Biogeography and the Evolution of Migration in Accipitrid Birds of Prey (Aves: Accipitriformes)

DOI: 10.2478/orhu-2014-0008 Phylogeny, historical biogeography and the evolution of migration in accipitrid birds of prey (Aves: Accipitriformes) Jenő nagy1 & Jácint tökölyi2* Jenő Nagy & Jácint Tökölyi 2014. Phylogeny, historical biogeography and the evolution of mig ration in accipitrid birds of prey (Aves: Accipitriformes). – Ornis Hungarica 22(1): 15–35. Abstract Migration plays a fundamental part in the life of most temperate bird species. The re gu lar, largescale seasonal movements that characterize temperate migration systems appear to have originated in parallel with the postglacial northern expansion of tropical species. Migratoriness is also in- fluenced by a number of ecological factors, such as the ability to survive harsh winters. Hence, understanding the origins and evolution of migration requires integration of the biogeographic history and ecology of birds in a phylogenetic context. We used molecular dating and ancestral state reconstruction to infer the origins and evolu- tionary changes in migratory behavior and ancestral area reconstruction to investigate historical patterns of range evolution in accipitrid birds of prey (Accipitriformes). Migration evolved multiple times in birds of prey, the ear- liest of which occurred in true hawks (Accipitrinae), during the middle Miocene period, according to our analy- ses. In most cases, a tropical ancestral distribution was inferred for the nonmigratory ancestors of migratory line- ages. Results from directional evolutionary tests indicate that migration evolved in the tropics and then increased the rate of colonization of temperate habitats, suggesting that temperate species might be descendants of tropi- cal ones that dispersed into these seasonal habitats. -
2013 the African Raptor Databank Or ARDB Was Launched
AFRICAN RAPTOR DATABANK first year report: 2013 The African Raptor Databank or ARDB was launched at the 13th PAOC in Arusha, October 2012. The project became possible thanks to the facilitation of The Peregrine Fund and ESRI in supplying important mapping software. A five year period is planned for data gathering to enable comprehensive assessment of the conservation status of each species of African raptor. The project also aims to make use of raptors as ideal indicator species for monitoring the health of African environments. The project depends on the support of raptor biologists, birdwatchers and general enthusiasts in sharing their observations of African raptors. This is a summary of the data gathering exercises during our first year of operation in 2013. Since the last monthly update in early November 2013, there have been a further 1228 records added to the database during December (Tim Wacher: 769; Andre Botha: 297; Joseph Heymans: 162). This brings the database total to 57,547 records (of which 15,607 are historic records captured from the Snow Atlas). The following table displays contributions by country during 2013.
