Supercilium
The supercilium is a plumage feature found on the heads of some bird species. It is a stripe which runs from the base of the bird's beak above its eye, finishing somewhere towards the rear of the bird's head.Dunn and Alderfer (2006), p. 10 Also known as an "eyebrow", it is distinct from the eyestripe, which is a line that runs across the lores, and continues behind the eye. Where a stripe is present only above the lores, and does not continue behind the eye, it is called a supraloral stripe or simply supraloral. On most species which display a supercilium, it is paler than the adjacent feather tracts. The colour, shape or other features of the supercilium can be useful in bird identification. For example, the supercilium of the dusky warbler, an Old World warbler The Old World warblers are a large group of birds formerly grouped together in the bird family Sylviidae. They are not closely related to the New World warblers. The family held over 400 species in over 70 genera, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Louisiana Waterthrush
The Louisiana waterthrush (''Parkesia motacilla'') is a New World warbler, that breeds in eastern North America and winters in the West Indies and Central America. Plain brown above, it is white below, with black streaks and with buff flanks and undertail, distinguishing it from the closely related northern waterthrush. The habitats it prefers are streams and their surroundings, and other wet areas. Range The Louisiana waterthrush breeds in eastern North America from southernmost Canada and south through the eastern United States, excluding Florida and the coast. It is bird migration, migratory, wintering in Central America and the West Indies. This is a rare vagrant to the western United States. They are one of the earlier neotropical migrants to return to their breeding grounds in the spring, often completing their migration in late March or early April, which is almost two months before most other warblers reach their breeding grounds. They are also one of the earliest warbler ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radde's Warbler
Radde's warbler (''Phylloscopus schwarzi'') is a leaf warbler which breeds in Siberia. This warbler is strongly migratory and winters in Southeast Asia. The genus name ''Phylloscopus'' is from Ancient Greek ''phullon'', "leaf", and ''skopos'', "seeker" (from ''skopeo'', "to watch"). The specific ''schwarzi'' commemorates German astronomer Ludwig Schwarz (1822–1894). Description This is a warbler similar in size to a willow warbler. The adult has an unstreaked brown back and buff underparts. There is a very long prominent whitish supercilium, and the pointed bill is thicker than that of the similar dusky warbler. The legs are paler than dusky's, and the feet look large, reflecting the more terrestrial lifestyle of this warbler. The sexes are identical, as with most warblers, but young birds are yellower below. The call is a soft ''chick''. Distribution and habitat Radde's warbler breeds in southern parts of Central and Eastern Siberia as far east as Korea and Manchuria. It i ...

Northern Waterthrush
The northern waterthrush (''Parkesia noveboracensis'') is a species of ground-feeding migratory New World warbler of the genus ''Parkesia''. It breeds in the northern part of North America in Canada and the northern United States including Alaska, and winters in Central America, the West Indies and Florida, as well as in Venezuela, Colombia, and Ecuador. It is a rare vagrant to other South American countries and to western Europe. Its closest relative is the Louisiana waterthrush. Taxonomy The northern waterthrush was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's ''Systema Naturae''. He placed it with the wagtails in the genus '' Motacilla'' and coined the binomial name ''Motacilla noveboracensis''. Gmelin based his account on descriptions of the species by earlier authors, none of whom had coined a binomial name. In 1778 the French polymath the Comte de Buffon had described "La fauvette tachet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jack Snipe
The jack snipe or jacksnipe (''Lymnocryptes minimus'') is a small stocky wader. It is the smallest snipe, and the only member of the genus ''Lymnocryptes''. Features such as its sternum and its continuous 'bobbing up and down' make it quite distinct from other snipes or woodcocks. Taxonomy The jack snipe was formally described in 1764 by the Danish zoologist Morten Thrane Brünnich under the binomial name ''Scolopax minima''. He specified the type locality as the Danish island of Christiansø. Brünnich based his account on "La petite béccassine" that had been described and illustrated in 1760 by the French zoologist Mathurin Jacques Brisson. The jack snipe is now the only species placed in the genus ''Lymnocryptes'' that was introduced in 1826 by the German zoologist Friedrich Boie. The species is considered to be monotypic: no subspecies are recognised. The genus name ''Lymnocryptes'' is from Ancient Greek ''limne'', "marsh" and ''kruptos'', "hidden". The species name '' ...

Dusky Warbler
The dusky warbler (''Phylloscopus fuscatus'') is a leaf warbler which breeds in the east Palearctic. The genus name '' Phylloscopus'' is from Ancient Greek ''phullon'', "leaf", and ''skopos'', "seeker" (from ''skopeo'', "to watch"). The specific ''fuscatus'' is from Latin ''fuscus'' "dark". This warbler is strongly migratory and winters in South Asia and South-east Asia. It sometimes occurs in North America in Alaska, and has also occurred in California. This is an abundant bird of taiga bogs and wet meadows. The nest is built low in a bush, and 5–6 eggs are laid. Like most Old World warblers, this small passerine is insectivorous. The dusky warbler is prone to vagrancy as far as western Europe in October, despite a 3000 km distance from its breeding grounds. It has wintered in Great Britain Great Britain is an island in the North Atlantic Ocean off the north-west coast of continental Europe, consisting of the countries England, Scotland, and Wales.

Canada Warbler
The Canada warbler (''Cardellina canadensis'') is a small boreal songbird of the New World warbler family (Parulidae). It summers in Canada and northeastern United States and winters in northern South America. Taxonomy In 1760 the French zoologist Mathurin Jacques Brisson included a description of the Canada warbler in his ''Ornithologie'' based on a specimen collected in Canada. He used the French name ''Le gobe-mouche cendré de Canada'' and the Latin name ''Muscicapa Canadensis Cinerea''. The two stars (**) at the start of the section indicates that Brisson based his description on the examination of a specimen. Although Brissn coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature. When in 1766 the Swedish naturalist Carl Linnaeus updated his ''Systema Naturae'' for the twelfth edition, he added 240 species that had been previously described by Brisson. One of these was the Canada war ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pipit
The pipits are a cosmopolitan genus, ''Anthus'', of small passerine birds with medium to long tails. Along with the wagtails and longclaws, the pipits make up the family Motacillidae. The genus is widespread, occurring across most of the world, except the driest deserts, rainforest and the mainland of Antarctica. They are slender, often drab, ground-feeding insectivores of open country. Like their relatives in the family, the pipits are monogamous and territorial. Pipits are ground nesters, laying up to six speckled eggs. Taxonomy and systematics The genus ''Anthus'' was introduced in 1805 by German naturalist Johann Matthäus Bechstein. The type species was later designated as the meadow pipit. The generic name ''Anthus'' is the Latin word for a small bird of grasslands mentioned by Pliny the Elder. Molecular studies of the pipits suggested that the genus arose in East Asia around seven million years ago (Mya), during the Miocene, and that the genus had spread to the Americ ...

Broad-billed Sandpiper
The broad-billed sandpiper (''Calidris falcinellus'') is a small wader, wading bird. The scientific name is from Latin. The specific name ''falcinellus'' is from ''falx, falcis'', "a sickle." Some research suggests that it and some related species could be placed into a separate genus, ''Philomachus'', not presently recognized as valid. Description Broad-billed sandpipers are small waders, slightly smaller than the dunlin, but with a longer straighter beak, bill, and shorter legs. The breeding adult has patterned dark grey upperparts and white underparts with blackish markings on the breast. It has a pale crown stripe and supercilia. In the Boreal ecosystem, boreal winter, they are pale grey above and white below, like a winter dunlin, but retaining the head pattern. Juveniles have backs, similar to young dunlin, but the white flanks and belly and brown-streaked breast are distinctive. Contact call is a dry, whistling “dree-it, dree-it” and a clicking “dik dik”.

New World Warbler
The New World warblers or wood-warblers are a group of small, often colorful, passerine birds that make up the family Parulidae and are restricted to the New World. The family contains 120 species. They are not closely related to Old World warblers or Australian warblers. Most are arboreal, but some, like the ovenbird and the two waterthrushes, are primarily terrestrial. Most members of this family are insectivores. This group likely originated in northern Central America, where the greatest number of species and diversity between them is found. From there, they spread north during the interglacial periods, mainly as migrants, returning to the ancestral region in winter. Two genera, '' Myioborus'' and '' Basileuterus'', seem to have colonized South America early, perhaps before the two continents were linked, and together constitute most warbler species of that region. The scientific name for the family, Parulidae, originates from the fact that Linnaeus in 1758 named the n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saxicola Rubetra 2 Tom (Marek Szczepanek)
''Saxicola'' (Latin: ''saxum'', rock + ''incola'', dwelling in.), the stonechats or chats, is a genus of 15 species of small passerine birds restricted to the Old World. They are insectivores occurring in open scrubland and grassland with scattered small shrubs. Taxonomy The genus was introduced by the German naturalist Johann Matthäus Bechstein in 1802. The type species was subsequently designated as the European stonechat. The name ''Saxicola'' is from Latin ''saxum'', ''saxi'' "stone" and ''-cola'' "dweller". The genus was formerly included in the thrush family Turdidae, but as with several other related genera, has now been shown to be correctly classified in the Old World flycatcher family Muscicapidae, in which it is most closely related to the genera '' Oenanthe'' (wheatears) and '' Campicoloides''. Genetic and behavioural evidence has also resulted in several new species being accepted in the genus in recent years, most notably the splitting of the former broad "specie ...

Plumage
Plumage () is a layer of feathers that covers a bird and the pattern, colour, and arrangement of those feathers. The pattern and colours of plumage differ between species and subspecies and may vary with age classes. Within species, there can be different colour morph (zoology), morphs. The placement of feathers on a bird is not haphazard but rather emerges in organized, overlapping rows and groups, and these are known by standardized names. Most birds moult twice a year, resulting in a breeding or ''nuptial plumage'' and a ''basic plumage''. Many ducks and some other species such as the red junglefowl have males wearing a bright nuptial plumage while breeding and a drab ''eclipse plumage'' for some months afterward. The painted bunting's juveniles have two inserted moults in their first autumn, each yielding plumage like an adult female. The first starts a few days after fledging replacing the ''juvenile plumage'' with an ''auxiliary formative plumage''; the second a month o ...

Old World Warbler
The Old World warblers are a large group of birds formerly grouped together in the bird family Sylviidae. They are not closely related to the New World warblers. The family held over 400 species in over 70 genera, and were the source of much taxonomic confusion. Two families were split out initially, the cisticolas into Cisticolidae and the kinglets into Regulidae. In the past 20–30 years they have been the subject of much research and many species are now placed into other families, including the Acrocephalidae, Cettiidae, Phylloscopidae, and Megaluridae. In addition some species have been moved into existing families or have not yet had their placement fully resolved. Only a small number of warblers, in just two genera, are now retained in the family Sylviidae. Characteristics Most Old World warblers are of generally undistinguished appearance, though some species are boldly marked. The sexes are often identical, but may be clearly distinct, notably in the genera '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
