Foliage Gleaning
Gleaning is a feeding strategy by birds in which they catch invertebrate prey, mainly arthropods, by plucking them from foliage or the ground, from crevices such as rock faces and under the eaves of houses, or even, as in the case of ticks and lice, from living animals. This behavior is contrasted with hawking insects from the air or chasing after moving insects such as ants. Gleaning, in birds, does not refer to foraging for seeds or fruit. Gleaning is a common feeding strategy for some groups of birds, including nuthatches, tits (including chickadees), wrens, woodcreepers, treecreepers, Old World flycatchers, Tyrant flycatchers, babblers, Old World warblers, New World warblers, Vireos and some hummingbirds and cuckoos. Many birds make use of multiple feeding strategies, depending on the availability of different sources of food and opportunities of the moment.

African Penduline-Tit (Anthoscopus Caroli)
The grey penduline tit (''Anthoscopus caroli''), also known as the African penduline-tit, is a species of bird in the family Remizidae. It is found in Angola, Botswana, Burundi, Republic of the Congo, Democratic Republic of the Congo, Eswatini, Kenya, Malawi, Mozambique, Namibia, Rwanda, South Africa, Tanzania, Uganda, Zambia, and Zimbabwe. Its natural habitats are subtropical or tropical dry forests, dry savanna, and moist savanna. At in length and a weight of , it is one of the smallest species of bird found in Africa, along with its cousin the Cape penduline tit and the perhaps smaller mouse-colored penduline tit and the tit hylia. Taxonomy The grey penduline tit was species description, formally described in 1871 by the English ornithologist Richard Bowdler Sharpe from a specimen that had been collected in the Ovaquenyama or Oukwanyama district of Damaraland. This is now northern Namibia. Sharpe coined the binomial name ''Aegithalus caroli''. This tit is now placed in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Common Chiffchaff
The common chiffchaff (''Phylloscopus collybita''), or simply the chiffchaff, is a common and widespread leaf warbler which breeds in open woodlands throughout northern and temperate Europe and the Palearctic. It is a migratory passerine which winters in southern and western Europe, southern Asia and north Africa. Greenish-brown above and off-white below, it is named onomatopoeically for its simple ''chiff-chaff'' song. It has a number of subspecies, some of which are now treated as full species. The female builds a domed nest on or near the ground, and assumes most of the responsibility for brooding and feeding the chicks, whilst the male has little involvement in nesting, but defends his territory against rivals, and attacks potential predators. A small insectivorous bird, it is subject to predation by mammals, such as cats and mustelids, and birds, particularly hawks of the genus ''Accipiter''. Its large range and population mean that its status is secure, although one su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beak
The beak, bill, or rostrum is an external anatomical structure found mostly in birds, but also in turtles, non-avian dinosaurs and a few mammals. A beak is used for eating, preening, manipulating objects, killing prey, fighting, probing for food, courtship, and feeding young. The terms ''beak'' and ''rostrum'' are also used to refer to a similar mouth part in some ornithischians, pterosaurs, cetaceans, dicynodonts, anuran tadpoles, monotremes (i.e. echidnas and platypuses, which have a beak-like structure), sirens, pufferfish, billfishes and cephalopods. Although beaks vary significantly in size, shape, color and texture, they share a similar underlying structure. Two bony projections – the upper and lower mandibles – are covered with a thin keratinized layer of epidermis known as the rhamphotheca. In most species, two holes called ''nares'' lead to the respiratory system. Etymology Although the word "beak" was, in the past, generally restricted to the sharpened bills o ...

Red-eyed Vireo
The red-eyed vireo (''Vireo olivaceus'') is a small American songbird. It is somewhat warbler-like but not closely related to the New World warblers (Parulidae). Common across its vast range, this species is not considered threatened by the IUCN. "Vireo" is a Latin word referring to a green migratory bird, perhaps the female golden oriole, possibly the European greenfinch. The specific ''olivaceus'' is New Latin for ''olive-green'', from Latin ''oliva'' "olive". Description and systematics Adults are mainly olive-green on the upper parts with white underparts; they have a red iris and a grey crown edged with black. There is a dark blackish line through the eyes and a wide white stripe just above that line. They have thick blue-grey legs and a stout bill. They are yellowish on the flanks and undertail coverts (though this is faint in some populations). In the past, the yellow-green vireo (''V. flavoviridis''), the chivi vireo (''V. chivi''), and the Noronha vireo (''V. gracili ...

Ruby-crowned Kinglet
The ruby-crowned kinglet (''Corthylio calendula'') is a very small passerine bird found throughout North America. It is a member of the kinglet family. The bird has olive-green plumage with two white wing bars and a white eye-ring. Males have a red crown patch, which is usually concealed. The sexes are identical (apart from the crown), and juveniles are similar in plumage to adults. It is one of the smallest songbirds in North America. The ruby-crowned kinglet is not closely related to other kinglets, and is put in its own genus, ''Corthylio''. Three subspecies are currently recognized. The kinglet is migratory, and its range extends from northwest Canada and Alaska south to Mexico. Its breeding habitat is spruce-fir forests in the northern and mountainous regions of the United States and Canada. The ruby-crowned kinglet builds a cup-shaped bird nest, nest, which may be pensile or placed on a tree branch and is often hidden. It lays up to 12 eggs, and has the largest clutch of any ...

Black-capped Chickadee
The black-capped chickadee (''Poecile atricapillus'') is a small, non-migratory, North American songbird that lives in deciduous and mixed forests. It is a passerine bird in the tit family, the Paridae. It is the state bird of Massachusetts and Maine in the United States, and the provincial bird of New Brunswick in Canada. It is well known for its ability to lower its body temperature during cold winter nights, its good spatial memory to relocate the caches where it stores food, and its boldness near humans (sometimes feeding from the hand). Taxonomy In 1760, French zoologist Mathurin Jacques Brisson included a description of the black-capped chickadee in his ''Ornithologie'' based on a specimen collected in Canada. He used the French name and the Latin ''Parus Canadensis Atricapillus''. The two stars (**) at the start of the section indicates that Brisson based his description on the examination of a specimen. Although Brisson coined Latin names, these do not conform to the bi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

National Audubon Society
The National Audubon Society (Audubon; ) is an American non-profit environmental organization dedicated to conservation of birds and their habitats. Located in the United States and incorporated in 1905, Audubon is one of the oldest of such organizations in the world. There are completely independent Audubon Societies in the United States, which were founded several years earlier such as the Massachusetts Audubon Society and Connecticut Audubon Society. The society has nearly 500 local chapters, each of which is an independent 501(c)(3) non-profit organization voluntarily affiliated with the National Audubon Society. They often organize birdwatching field trips and conservation-related activities. It also coordinates the Christmas Bird Count held each December in the U.S., a model of citizen science, in partnership with Cornell Lab of Ornithology, and the Great Backyard Bird Count each February. Together with Cornell, Audubon created eBird, an online database for bird observat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vireo
The vireos make up a family, Vireonidae, of small to medium-sized passerine birds found in the New World (Canada to Argentina, including Bermuda and the West Indies) and Southeast Asia. "Vireo" is a Latin word referring to a green migratory bird, perhaps the female golden oriole, possibly the European greenfinch. They are typically dull-plumaged and greenish in color, the smaller species resembling wood warblers apart from their heavier bills. They range in size from the Chocó vireo, dwarf vireo and lesser greenlet, all at around 10cm and 8g, to the peppershrikes and shrike-vireos at up to 17cm and 40g.Forshaw, Joseph & Parkes, Kenneth C. 1991. ''Encyclopaedia of Animals: Birds,'' p. 209. Merehurst Press, London. Distribution and habitat Most species are found in Middle America and northern South America. Thirteen species of true vireos occur farther north, in the United States, Bermuda and Canada; of these all but Hutton's vireo are migratory. Members of the famil ...

Bay-breasted Warbler
The bay-breasted warbler (''Setophaga castanea'') is a small species of songbird in the New World warbler family, Parulidae. It is one of thirty-four species in the diverse genus ''Setophaga.'' Like all songbirds, or passerines, the species is classified in the order Passeriformes. Distribution Bay-breasted warblers breed in the boreal spruce-fir forests of eastern and central Canada, as well as the extreme northern United States. The species winters in the wet lowland forests of northeastern South America, the Caribbean, and southern Central America, and may be seen during spring and fall migration across the eastern half of the United States in a variety of vegetative communities. Many individuals cross the Gulf of Mexico on their long-distance migration, although some travel north and south along the Mexican shore. Diet and behavior In the breeding season, bay-breasted warblers feed primarily on insects and spiders, especially the spruce budworm (''Choristoneura fumiferana'') ...

Nearctic Realm
The Nearctic realm is one of the eight biogeographic realms constituting the Earth's land surface. The Nearctic realm covers most of North America, including Greenland, Central Florida, and the highlands of Mexico. The parts of North America that are not in the Nearctic realm are Eastern Mexico, Southern Florida, coastal Central Florida, Central America, and the Caribbean islands, which, together with South America, are part of the Neotropical realm. Major ecological regions The World Wildlife Fund (WWF) divides the Nearctic into four bioregions, defined as "geographic clusters of ecoregions that may span several habitat types, but have strong biogeographic affinities, particularly at taxonomic levels higher than the species level (genus, family)." Canadian Shield The Canadian Shield bioregion extends across the northern portion of the continent, from the Aleutian Islands to Newfoundland. It includes the Nearctic's Arctic Tundra and Boreal forest ecoregions. In terms of flo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peterson Field Guides
The Peterson Field Guides (PFG) are a popular and influential series of United States, American field guides intended to assist the layman in identification of birds, plants, insects and other natural phenomena. The series was created and edited by renowned ornithologist Roger Tory Peterson (1908–1996). His inaugural volume was the classic 1934 book ''A Field Guide to the Birds'', published (as were all subsequent volumes) by the Houghton Mifflin Company. The PFG series utilized what became known as the Peterson Identification System, a practical method for field identification which highlights readily noticed visual features rather than focusing on the technical features of interest to scientists. The series both reflected and contributed to awareness of the emerging environmental movement. Most books in this series use a section of plates of drawings (usually reduced from commissioned paintings) rather than photographs of the subject species, grouped at the center of the book. ...
