Harry Kirke Swann
Harry Kirke Swann (18 March 1871 near Ewhurst, Surrey – 14 April 1926, Barnet, London) was an English ornithologist and author of books on birds. His research interests were birds of prey and British avifauna. Biography Swann was initially privately taught. He then attended Roan School in Greenwich, London, and finally had a private tutor in Brighton. His interest in nature and especially in ornithology was awakened in his earliest childhood. At the age of 20, he traveled to the eastern Canadian province of Nova Scotia and in 1895 published an account of his Canadian travels under the title ''Nature in Acadie'' in 1895. After returning to England in 1892, he founded the journal ''The Naturalist's Journal: A Monthly Medium for Collectors and Students'', which under the editorship of Seth Lister Mosley (1848-1929) was renamed in 1896 ''The Naturalist's Journal, and Naturalist's Guide''. In this journal, in 1892, Swann's first article,'' Bird Life on Epsom Common'', was published. In ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lore (anatomy)
The lore (adj. loreal) is the region between the eyes and nostrils of birds, reptiles, and amphibians. Ornithology In ornithology, the lore is the region between the eye and bill on the side of a bird's head. This region is sometimes featherless, and the skin may be tinted, as in many species of the cormorant family. This area, which is directly in front of the eye, features a "loral stripe" in many bird species including the red-capped plover. Herpetology In amphibians and reptiles, lore pertains to the regions immediately adjacent to the eyes and between the eyes and nostrils. These are analogous to the lore on birds which corresponds to the region between the eye and the beak. In snakes and reptiles, a loreal scale also refers to the scales which lie between the eye and the nostril. In crotaline snakes (pit vipers), loreal pits are present on either side of the head.Campbell JA, Lamar WW. 2004. The Venomous Reptiles of the Western Hemisphere. 2 volumes. Comstock Publishing ...

Birds Described In 1919
Birds are a group of warm-blooded vertebrates constituting the class Aves (), characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a strong yet lightweight skeleton. Birds live worldwide and range in size from the bee hummingbird to the common ostrich. There are over 11,000 living species and they are split into 44 orders. More than half are passerine or "perching" birds. Birds have wings whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the loss of flight in some birds, including ratites, penguins, and diverse endemic island species. The digestive and respiratory systems of birds are also uniquely adapted for flight. Some bird species of aquatic environments, particularly seabirds and some wate ...

Micrastur
Forest falcons are members of the genus ''Micrastur'', part of the family Falconidae. They are endemic to the Americas, found from Mexico in the north, south through Central America and large parts of South America, and as far south as northern Argentina. Most are restricted to humid tropical and subtropical forests, but the two most widespread species, the collared and the barred forest falcon, also range into drier and more open habitats. Forest falcons, like most ''Accipiter''-type hawks (but unlike other falcons), are adapted for agility in thick cover rather than outright speed in the open air. They have short wings, long tails, and extraordinarily acute hearing. While generally visually inconspicuous, their songs are commonly heard. Their diet is a mixture of birds, mammals, and reptiles. Hunting is often performed in goshawk fashion: the bird takes up a perch in an inconspicuous position and waits for a prey species to pass, then strikes with a short, rapid pursuit. Fore ...

IUCN
The International Union for Conservation of Nature (IUCN) is an international organization working in the field of nature conservation and sustainable use of natural resources. Founded in 1948, IUCN has become the global authority on the status of the natural world and the measures needed to safeguard it. It is involved in data gathering and Data analysis, analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through buildin ...

Mesomys
''Mesomys'' is a genus of South American spiny rats in the family Echimyidae. The genus name ''Mesomys'' derives from the two ancient greek words (), meaning "middle of, between", and (), meaning "mouse, rat". It refers to the fact that these rodents — literally the "middle mouse" — were considered an intermediate form between the genus ''Loncheres'' and the genus ''Echinomys'', both of which are now known to be synonyms of ''Echimys''. Extant species Phylogeny ''Mesomys'' is a member of the Echimyini clade of arboreal Echimyidae rodents. The closest relative of ''Mesomys'' is ''Lonchothrix'', reflecting the fact that these taxa have once been classified in the Eumysopinae Echimyidae is the family of neotropical spiny rats and their fossil relatives. This is the most species-rich family of hystricognath rodents. It is probably also the most ecologically diverse, with members ranging from fully arboreal to terre ..., a subfamily now recognized as an artificial asse ...

American Ornithological Society
The American Ornithological Society (AOS) is an ornithological organization based in the United States. The society was formed in October 2016 by the merger of the American Ornithologists' Union (AOU) and the Cooper Ornithological Society. Its members are primarily professional ornithologists, although membership is open to anyone with an interest in birds. The society publishes the two scholarly journals, Ornithology' (formerly ''The Auk)'' and Ornithological Applications' (formerly '' The Condor)'' as well as the '' AOS Checklist of North American Birds''. The American Ornithological Society claims the authority to establish standardized English bird names throughout North and South Americas. In 2013, the American Ornithologists' Union (AOU) announced a collaboration with the Cooper Ornithological Society, streamlining operations through joint meetings, a shared publishing office, and a reorientation of their journals. By October 2016, the AOU ceased its independent status, m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Secondaries (birds)
Flight feathers (''Pennae volatus'') are the long, stiff, asymmetrically shaped, but symmetrically paired pennaceous feathers on the Bird wing, wings or tail of a bird; those on the wings are called remiges (), singular remex (), while those on the tail are called rectrices ( or ), singular rectrix (). The primary function of the flight feathers is to aid in the generation of both thrust and lift (force), lift, thereby enabling bird flight, flight. The flight feathers of some birds perform additional functions, generally associated with territorial displays, courtship rituals or feeding methods. In some species, these feathers have developed into long showy plumes used in visual courtship displays, while in others they create a sound during display flights. Tiny serrations on the leading edge of their remiges help owls to fly silently (and therefore hunt more successfully), while the extra-stiff rectrices of woodpeckers help them to brace against tree trunks as they hammer on ...
