Gnatcatcher
The gnatcatchers are a family of small passerine birds called ''Polioptilidae''. The 22 species occur in North and South America (except for the far south and the high Andean regions). Most species of this mainly tropical and subtropical group are resident, but the blue-grey gnatcatcher of the United States and southern Canada migrates south in winter. They are close relatives of the wrens.Atwood, J. & Lerman, S. (2006) Family Polioptilidae (Gnatcatchers). pp. 350–377 in: del Hoyo, J., A. Elliott, and D. Christie. eds (2006). ''Handbook of Birds of the World'' Vol. 11. Old World Flycatchers to Old World Warblers. Lynx Edicions, Barcelona. Description These dainty birds are intermediate between Old World warblers and wrens in their structure and habits, moving restlessly through foliage seeking insects. The gnatcatchers are mainly soft bluish grey in color, and have the typical insectivore's long sharp bill. Many species have distinctive black head patterns (especially ma ...

Polioptila
''Polioptila'' is a genus of small insectivorous birds in the family Polioptilidae. They are found in North and South America. The genus ''Polioptila'' was introduced by the English zoologist Philip Sclater in 1855. Although he listed several members, he did not specify a type species. This was designated by the American ornithologist Spencer Baird in 1864 as ''Montacilla caerulea'', Linnaeus, now the blue-grey gnatcatcher, ''Polioptila caerulea''. The name of the genus combines the Ancient Greek Ancient Greek (, ; ) includes the forms of the Greek language used in ancient Greece and the classical antiquity, ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Greek ... words ''πολιος'' ''polios'' "grey" and ''πτιλον'' "plumage". The genus contains 18 species: * Rio Negro gnatcatcher, ''Polioptila facilis'' – split from ''P. guianensis'' * Guianan gnatcatcher, ''Polioptila guiane ...

Blue-grey Gnatcatcher
The blue-gray gnatcatcher (''Polioptila caerulea'') is a very small gnatcatcher native to North America. Description It is in length, 6.3 in (16 cm) in wingspan, and weighing only . Adult males are blue-gray on the upperparts with white underparts, slender dark bill, and a long black tail edged in white. Females are less blue, while juveniles are greenish-gray.

Polioptila Plumbea
The tropical gnatcatcher (''Polioptila plumbea'') is a small active insectivorous songbird, which is a resident species throughout a large part of northern South America. It was formerly considered as conspecific with the white-browed gnatcatcher and the Marañón gnatcatcher. Taxonomy The tropical gnatcatcher was formally described in 1788 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's ''Systema Naturae''. He placed it in the genus ''Todus'', coined the binomial name ''Todus plumbeus'' and specified the type locality as Suriname in South America. The specific epithet ''plumbeus'' is Latin meaning "plumbeous" or "lead-coloured". Gmelin based his account on the "Plumbeous tody" that had been described in 1782 by the English ornithologist John Latham in his book ''A General Synopsis of Birds''. Latham had examined a specimen in the collection of the British Museum. The tropical gnatcatcher is now one of 17 gnatcatchers pla ...

Polioptila Guianensis
The Guianan gnatcatcher (''Polioptila guianensis'') is a species of bird in the family Polioptilidae. It is found in Brazil, French Guiana, Guyana, Suriname, and Venezuela. Taxonomy and systematics The Guianan gnatcatcher is monotypic. Two former subspecies, Rio Negro gnatcatcher (''Polioptila facilis'') and Para gnatcatcher (''P. paraensis'', also called Klages's gnatcatcher) have been treated as separate species since mid-2019. The Inambari gnatcatcher (''P. attenboroughi'') and Iquitos gnatcatcher (''P. clementsi''), which were accepted as new species at about that time, are very closely related to it.Remsen, J.

California Gnatcatcher
The California gnatcatcher (''Polioptila californica'') is a small, insectivorous bird which frequents dense coastal sage scrub growth. This species was recently split from the similar black-tailed gnatcatcher of the Sonoran and Chihuahuan deserts. This bird is often solitary, but joins with other birds in winter flocks. Description The male California gnatcatcher is dusky gray overall, distinguished only by its black crown and thin black beak. It has a long, thin black tail with narrow white tips and edges on the underside of the tail feathers. However, the male loses its plumage colors by winter and obtains a plumage color similar to the females. The female is similar to the male, but with a blue-gray instead of a black crown. In its range from coastal Southern California south through Baja California and Baja California Sur, this inconspicuous non- migratory resident is most often seen flitting hastily into undergrowth, or heard giving its call, which sounds like a kitten's ...

Polioptila Clementsi
The Iquitos gnatcatcher (''Polioptila clementsi'') is a bird in the family Polioptilidae. It was first described in 2005. It is known only from the Allpahuayo-Mishana National Reserve, west of Iquitos, Peru. Taxonomy and systematics The Iquitos gnatcatcher is a member of the Guianan gnatcatcher (''Polioptila guianensis'') complex. It was accepted as a new species by the South American Classification Committee of the American Ornithological Society (SACC/AOS) in July 2006 and by other taxonomic bodies at about that time.Remsen, J.

Polioptila Dumicola
The masked gnatcatcher (''Polioptila dumicola'') is a small songbird in the family Polioptilidae. It is found in Argentina, Bolivia, Brazil, Paraguay, and Uruguay. Taxonomy and systematics The masked gnatcatcher has three recognized subspecies, the nominate ''Polioptila dumicola dumicola'', ''P. d. saturata'', and ''P. d. berlepschi''. The last subspecies differs in both plumage and voice from the other two and may represent a separate species.Remsen, J. V., Jr., J. I. Areta, E. Bonaccorso, S. Claramunt, A. Jaramillo, D. F.

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] [Amazon] |
Handbook Of Birds Of The World
The ''Handbook of the Birds of the World'' (HBW) is a multi-volume series produced by the Spanish publishing house Lynx Edicions in partnership with BirdLife International. It is the first handbook to cover every known living species of bird. The series was edited by Josep del Hoyo, Andrew Elliott, Jordi Sargatal and David A. Christie. All 16 volumes have been published. For the first time an animal class will have all the species illustrated and treated in detail in a single work. This has not been done before for any other group in the animal kingdom. Material in each volume is grouped first by family, with an introductory article on each family; this is followed by individual species accounts (taxonomy, subspecies and distribution, descriptive notes, habitat, food and feeding, breeding, movements, status and conservation, bibliography). In addition, all volumes except the first and second contain an essay on a particular ornithological theme. More than 200 renowned spec ...

Passerine
A passerine () is any bird of the order Passeriformes (; from Latin 'sparrow' and '-shaped') which includes more than half of all bird species. Sometimes known as perching birds, passerines generally have an anisodactyl arrangement of their toes (three pointing forward and one back), which facilitates perching. With more than 140 families and some 6,500 identified species, Passeriformes is the largest order of birds and one of the most diverse clades of terrestrial vertebrates, representing 60% of birds.Ericson, P.G.P. et al. (2003Evolution, biogeography, and patterns of diversification in passerine birds ''J. Avian Biol'', 34:3–15.Selvatti, A.P. et al.
