Gnatcatcher
The Gnatcatchers are a family of small passerine birds called Polioptilidae. The 21 species occur in North America, 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 bird migration, 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 colour, and have the typical insectivore's long sharp bill. Many species have distinctive black he ...

Polioptila Plumbea
The tropical gnatcatcher (''Polioptila plumbea'') is a small active insectivorous songbird, which is a resident species throughout a large part of the Neotropics. There are large geographical variations in its voice and plumage, resulting in some populations sometimes being considered separate species, notably the ''bilineata'' group as the white-browed gnatcatcher, and the taxon ''maior'' as the Marañón gnatcatcher. Taxonomy The tropical gnatcatcher was described by the German naturalist Johann Friedrich Gmelin in 1788 and given the binomial name ''Todus plumbeus''. He specified the type locality as Suriname in South America. It is now placed in the genus ''Polioptila'' which was introduced by the English zoologist Philip Sclater in 1855. Description The adult tropical gnatcatcher is long, and weighs . Its " jizz" is similar to that of other gnatcatchers; a small bird with a relatively long thin bill, a long frequently cocked tail, grey upperparts and whitish underparts. T ...

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 words ''πολιος'' ''polios'' "grey" and ''πτιλον'' "plumage". The genus contains 17 species: * Rio Negro gnatcatcher, ''Polioptila facilis'' – split from ''P. guianensis'' * Guianan gnatcatcher, ''Polioptila guianensis'' * Slate-throated gnatcatcher, ''Polioptila schistaceigula'' * Para gnatcatcher, ''Polioptila paraensis'' – split from ''P. guianensis'' * Iquitos gnatcatcher, ''Polioptila clementsi'' – described in 2005 * Inambari gnatcatcher, ''Polioptila attenb ...

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 long 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 ...

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.

Sittidae
The nuthatches () constitute a genus, ''Sitta'', of small passerine birds belonging to the family Sittidae. Characterised by large heads, short tails, and powerful bills and feet, nuthatches advertise their territory using loud, simple songs. Most species exhibit grey or bluish upperparts and a black eye stripe. Most nuthatches breed in the temperate or montane woodlands of the Northern Hemisphere, although two species have adapted to rocky habitats in the warmer and drier regions of Eurasia. However, the greatest diversity is in Southern Asia, and similarities between the species have made it difficult to identify distinct species. All members of this genus nest in holes or crevices. Most species are non-migratory and live in their habitat year-round, although the North American red-breasted nuthatch migrates to warmer regions during the winter. A few nuthatch species have restricted ranges and face threats from deforestation. Nuthatches are omnivorous, eating mostly insects, ...

Certhiidae
The treecreepers are a family, Certhiidae, of small passerine birds, widespread in wooded regions of the Northern Hemisphere and sub-Saharan Africa. The family contains eleven species in two genera, ''Certhia'' and ''Salpornis''. Their plumage is dull-coloured, and as their name implies, they climb over the surface of trees in search of food. Taxonomy and systematics The family consists of two subfamilies, each with one genus. Their distinctive anatomical and behavioural characteristics are discussed in their respective articles. *Subfamily Certhiinae, genus ''Certhia'', is the typical treecreepers, with eight species found in Europe and Asia, and one, the brown creeper, in North America. *Subfamily Salpornithinae, genus ''Salpornis'', contains only the Indian spotted creeper and African spotted creeper. Some taxonomists place the nuthatches and treecreepers in a larger grouping with the wrens and gnatcatchers. This superfamily, the Certhioidea, was based on phylogenetic studie ...

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 specia ...

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 are distinguished from other orders of birds by the 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 clade of birds and among the most diverse clades of terrestrial vertebrates, representing 60% of birds.Ericson, P.G.P. et al.
