Kites, Eagles, Hawks and Alli Text extracted from Gill B.J.; Bell, B.D.; Chambers, G.K.; Medway, D.G.; Palma, R.L.; Scofield, R.P.; Tennyson, A.J.D.; Worthy, T.H. 2010. Checklist of the birds of New Zealand, Norfolk and Macquarie Islands, and the Ross Dependency, Antarctica. 4th edition. Wellington, Te Papa Press and Ornithological Society of New Zealand. Pages 169-171. Order ACCIPITRIFORMES: Secretary-bird, Kites, Eagles, Hawks and Allies The diurnal birds-of-prey (Accipitridae, Sagittariidae, Falconidae and Cathartidae) were long grouped in a single order usually named Falconiformes (from Sharpe 1874, Cat. Birds Brit. Mus. 1: ix, 1 – suborder Falcones; type Falco Linnaeus), e.g. Peters (1934), Wetmore (1960), Stresemann & Amadon (1979), del Hoyo et al. (1994). However, the strict monophyly of this group is strongly doubted, as revealed by the DNA-hybridisation studies (Sibley et al. 1988, Sibley & Ahlquist 1990) and karyological, pterylogical and morphological studies reviewed in Holdaway (1994a). This has resulted in the removal of Cathartidae, either to its own order or to within storks to which they are most closely related. Increasing evidence suggests that Falconidae and Accipitridae are not closely related (e.g. Fain & Houde 2004, Ericson et al. 2006). We follow Christidis & Boles (2008) in treating these two groups as separate orders. Within Accipitriformes as so defined, genera, as listed by, e.g. del Hoyo et al. (1994) and Dickinson (2003), are demonstrably non-monophyletic based on nuclear and mitochondrial genome data (Bunce et al. 2005, Helbig et al. 2005, Lerner & Mindell 2005, Griffiths et al. 2007). As a result of these and other phylogenetic studies concerning Aquila, Sangster et al. (2005) have transferred Hieraaetus pennatus Gmelin, 1788 to Aquila as Aquila pennata, thereby making Hieraaetus Kaup, 1844 a synonym of Aquila Brisson, 1760. As they restricted comment to Western Palaearctic species, it is not clear what the total advocated composition of Aquila is. However, in such a broadened definition of Aquila, Harpagornis, which was shown by Bunce et al. (2005) to be the sister taxon of Hieraaetus morphnoides and H. pennatus, is a derivative of the common ancestor of all “booted eagles”. Given this, we follow Sangster et al. (2005), Barthel & Helbig (2005), Mebs & Schmidt (2006) and Commission de l’Avifaune Française (2007) in recognising only one genus for the “booted eagles” of the subfamily Aquilinae (sensu Lerner & Mindell 2005). None of the family-group names in Vieillot’s Analyse d’une nouvelle ornithologie élémentaire (1816) were based on Linnaean generic names (Bock 1994), so none are valid under ICZN (1999). Accipitrini Vieillot, 1816: 22, while designated as a family, does not provide the basis of a valid family-group name. ICZN (1999) does not rule on names above family-group level, so Vieillot names are available for such names. Accipitriformes Vieillot may be used for Accipitridae and Sagittariidae. Brodkorb (1964) provided detailed synonymies of all nomenclatorial groupings that have been proposed. Family ACCIPITRIDAE Vigors: Kites, Eagles, Hawks and Allies Subfamily ACCIPITRINAE Vigors: Kites, Eagles, Hawks and Allies Accipitrina Vigors, 1824: Zoological Journal 1: 313 – Type genus Accipiter Brisson, 1760. Within this subfamily we include: Milvinae Vigors, 1824; Aquilinae Vigors, 1824; and Circinae Bonaparte, 1838. The taxon Haliaeetus australis (Harrison & Walker, 1973) is deleted from the New Zealand list as it is considered to be based on bones of the Alaskan bald eagle H. leucocephalus mistakenly mixed with bones from the Chatham Islands after their collection by Forbes (Millener 1999, Worthy & Holdaway 2002).

Following Baker-Gabb (1979) and Checklist Committee (1990), we do not recognise any subspecies. Widely distributed on the New Zealand mainland, its range having extended greatly with human settlement. Considered to have colonised New Zealand only after human settlement and the extinction of Circus teauteensis (Holdaway et al. 2001: 131, as C. eylesi; Worthy & Holdaway 2002). As it is a recent colonist to New Zealand we discard the former name “Australasian harrier” (Checklist Committee 1990) in favour of the Australian name, swamp harrier. A few very late Holocene fossils and numerous midden records from widely distributed sites in both North and South Islands and the Chathams. .

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.

  • Studies of Less Familiar Birds Ij2 Lesser Spotted Eagle B.-U
    Studies of less familiar birds ij2 Lesser Spotted Eagle B.-U. Meyburg Plates 61-64. Of all European eagles, the Lesser Spotted Eagle Aquila pomarina has the smallest world breeding range, the nominate race being confined to eastern parts of Germany, Poland, eastern Czechoslovakia, Hun­ gary, Yugoslavia, Romania, Bulgaria, north-east Greece, western Turkey (Thrace), and the Soviet Union north to Leningrad and east to about 35°E. There are no published records of proved breeding in eastern Austria this century, though pairs from Hungary hunt over the land around Lake Neusiedl. There is no clear information on the current position in the Caucasus and the south Caspian lowlands. In Germany the breeding area stretches only to the north of Berlin, westwards beyond the rivers Oder and Neisse but stopping short of the Elbe. In 1969 there were 53 known broods in this area, and possibly a further nine (H. Weber in Glutz von Blotzheim et al. 1971). Even at the beginning of this century, the breeding range extended much further westwards, at least as far as the River Weser in Niedersachsen. A second subspecies, A. p. hastata, breeds in parts of India, in particular the Ganges Valley and West Bengal, and also in Bangla Desh. Hardly anything is known about this form, which appears to be rare. The first autumn plumage is said to be quite different from that of the nominate race, which has led some authors to treat it as a separate species. The Lesser Spotted Eagle presents a very difficult problem to field and museum ornithologists alike—the clear differentiation between it and the very closely related Spotted Eagle A.

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.

The northward dispersionin fall is well illus- trated by September and October returns from Montana, Wyoming, North Dakota, South Dakota and Idaho. Although migration may begin early, many young remain in the breeding grounds until October. The returns show the principal wintering grounds for the Utah birds to be the Salton Sea region of southernCalifornia and the lower coast of Texas from Corpus Christi to Mexico. Eighty-sevenpercent of the birds taken were less than one year old; 10.6 percent were second-yearbirds, and two percent were third year or older. This ratio prompts the author to assumelogically that the first year is the critical one in the life of the bird insofar as shooting is concerned.

Received: June 20, 2020 / Accepted: August 27, 2020/ Published online: September 28, 2020 Abstract Birds of prey are important for maintaining ecosystems, since they can regulate the populations of vertebrates and invertebrates. However, anthropic activities, like habitat fragmentation, have been decreasing the number of birds of prey, affecting the habitat ecological relations and, decreasing biodiversity. Our objective was to evaluate species of birds of prey (Accipitriformes and Falconiformes) in a protected area of the Atlantic forest in northeastern Brazil. The area was sampled for 17 months using fixed points and walking along a pre-existing trail. Birds of prey were classified by their Punctual Abundance Index, threat status and forest dependence. Sixteen birds of prey were recorded, being the most common Rupornis magnirostris and Caracara plancus. Most species were considered rare in the area and not dependent of forest vegetation.

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.
