SEPTEMBER1997 LETTERS 287 AravaipaCreek, Arizona. Almost immediatelyat leastsix Elf Owls beganvocalizing from dispersedlocations around our campsiteand at leastfour of them began making low passesat the Great Horned Owl. Before we could relocate the horned owl to a protectedenclosure, it wasstruck once in the head by an Elf Owl. Some nocturnal behaviorsmay not be well known or understood,not becausethey are rare, but becausethey are difficult to observe.This may changewith the increasedavailability of night vision equipment (P. Henson and J A Cooper 1994, Auk 111:1013-1018). Currently, observationsof nocturnal behaviorsare likely to be sporadicand anecdotal,and therefore unreported. Such information, however,may help in understandinga speciesbiology. For example, other researchershave observedgroup mobbing by Elf Owls (F.R. Gehlbach,pers. comm.; B.A. Millsap, pers. comm.), but there are no publishedreports of the behavior.Our observations,and thoseof other researchers, suggestthat Elf Owlswill join together in mobbing and that they can be physicallyaggressive when defending their nestsagainst predators. We thank A. Duerr, T.S. Estabrookand R.L. Spauldingfor assistingwith the observations.We alsothank T. Brush, ER. Gehlbach, R. Glinski, P. Hardy, B.A. Millsap, G. Proudfoot and H.A.

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.

A Multi-Gene Phylogeny of Aquiline Eagles (Aves: Accipitriformes) Reveals Extensive Paraphyly at the Genus Level

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). -

In 1940, Bald Eagle was provided protection under the Bald and Golden Eagle Protection Act 2. In 1966, the southern subspecies was listed as federally endangered under the Endangered Species Preservation Act; the entire population in the contiguous United States was listed as endangered in 1978 under the 1973 Endangered Species Act (ESA). A significant increase in numbers of nesting pairs, productivity, and distribution allowed Bald Eagle to be reclassified from Endangered to Threatened in 1995 under the ESA 3. Bald Eagle was delisted in 2007, and numbers are considered to be stable to increasing across its range 4. The species has been assigned different state conservation ranks by the Wyoming Natural Diversity Database for the breeding season and nonbreeding season because the abundance of the species is different between seasons. NATURAL HISTORY Taxonomy: Bald Eagle is a member of the family Accipitridae, which includes kites, eagles, harriers, and hawks 5. There are two subspecies of Bald Eagle; H. l. alascanus is found north of 40 degrees latitude across North America, including Wyoming, while H. l. leucocephalus is found south of 40 degrees latitude in the Gulf coast states 6. -

Extreme Variation in the Tails of Adult Harlan’S Hawks
EXTREME VARIATION IN THE TAILS OF ADULT HARLAN’S HAWKS William S. (Bill) Clark Some adult Harlan’s Hawks have tails somewhat similar to this one Bob Dittrick But many others have very different tails, both in color and in markings Harlan’s Hawk type specimen. Audubon collected this adult in 1830 in Louisiana (USA) and described it as Harlan’s Buzzard or Black Warrier - Buteo harlani It is a dark morph, the common morph for this taxon. British Museum of Natural History, Tring Harlan’s Hawk Range They breed in Alaska, Yukon, & ne British Columbia & winter over much of North America. It occurs in two color morphs, dark and light. The AOS considers Harlan’s Hawk a subspecies of Red- tailed Hawk, Buteo jamaicensis harlani, but my paper in Zootaxa advocates it as a species. Clark (2018) Taxonomic status of Harlan’s Hawk Buteo jamaicensis harlani (Aves: Accipitriformes) Zootaxa concludes: “It [Harlan’s Hawk] should be considered a full species based on lack of justification for considering it a subspecies, and the many differences between it and B. jamaicensis, which are greater than differences between any two subspecies of diurnal raptor.” Harlan’s Hawk is a species: 1. Lack of taxonomic justification for inclusion with Buteo jamaicensis. 2. Differs from Buteo jamaicensis by: * Frequency of color morphs; * Adult plumages by color morph, especially in tail pattern and color; * Neotony: Harlan’s adult & juvenile body plumages are almost alike; whereas those of Red-tails differ. * Extent of bare area on the tarsus. * Some behaviors. TYPE SPECIMEN - Upper tail is medium gray, with a hint of rufous and some speckling, wavy banding on one feather, & wide irregular subterminal band. -

Kenward Anatrack Ltd and IUCN-SSC European Sustainable Use Specialist Group, Wareham, UK Introduction Falconry is a type of recreational hunting. This chapter considers the conser- vation issues surrounding this practice. It provides a historical background and then discusses how falconry’s role in conservation has developed and how it could grow in the future. Falconry, as defi ned by the International Association for Falconry and Conservation of Birds of Prey (IAF), is the hunting art of taking quarry in its natural state and habitat with birds of prey. Species commonly used for hunt- ing include eagles of the genera Aquila and Hieraëtus, other ‘broad-winged’ members of the Accipitrinae including the more aggressive buzzards and their relatives, ‘short-winged’ hawks of the genus Accipiter and ‘long-winged’ falcons (genus Falco). Falconers occur in more than 60 countries worldwide, mostly in North America, the Middle East, Europe, Central Asia, Japan and southern Africa. Of these countries, 48 are members of the IAF.
