The 15-20 species of small passerine birds in the gnatcatcher family occur in North and South America (except far south and high Andean regions). The California Gnatcatcher ( Polioptila californica) is a small 10 Chordates ( Phylum Chordata) are a group of Animals that includes the Vertebrates together with several closely related Invertebrates Birds ( class Aves) are bipedal endothermic ( Warm-blooded) Vertebrate animals that lay eggs. SongBird is a Dutch Record label owned by Tijs Verwest and Arny Bink Spencer Fullerton Baird ( February 3, 1823 &ndash August 19, 1887) was an American ornithologist and Ichthyologist Birds ( class Aves) are bipedal endothermic ( Warm-blooded) Vertebrate animals that lay eggs. South America is a Continent of the Americas, situated entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a The Andes form the world's longest exposed Mountain range. They lie as a continuous chain of highland along the western coast of South America. Most species of this mainly tropical and subtropical group are resident, but the Blue-gray Gnatcatcher of the USA and southern Canada migrates south in winter. The Tropics are centered on the Equator and limited in Latitude by the Tropic of Cancer in the northern hemisphere at approximately 23°26' (23 The subtropics are the zones of the Earth immediately north and south of the tropic zone which is bounded by the Tropic of Cancer and the Tropic of The Blue-gray Gnatcatcher, Polioptila caerulea, is a very small Songbird. The United States of America —commonly referred to as the Country to "Dominion of Canada" or "Canadian Federation" or anything else please read the Talk Page Bird migration refers to the regular seasonal journeys undertaken by many species of Birds Bird movements include those made in response to changes in food availability They are close relatives of the wrens. The wrens are Passerine birds in the mainly New World family Troglodytidae.

These dainty birds are intermediate between "Old World warblers" and wrens in their structure and habits, moving restlessly through the foliage seeking insects. The " Old World Warblers " family Sylviidae are a family of small Passerine Bird species the names sylviid warblers The wrens are Passerine birds in the mainly New World family Troglodytidae. The gnatcatchers are mainly soft bluish grey in colour, and have the typical insectivore's long sharp bill. Many species have distinctive black head patterns (esp. males) and long, regularly cocked, black-and-white tails. The skulking gnatwrens are browner, more thickset, and with proportionally shorter tails and longer bills.

The gnatwrens typically occur in the undergrowth of dense, often humid, forest, while gnatcatchers, depending on the species involved, occur in anything from dry scrubby habitats (e. g. the California Gnatcatcher) to the canopy of humid Amazonian forest (e. The canopy is one of the uppermost levels of a Forest, below the emergent layer, formed by the Tree crowns Canopy trees refers to the trees The Amazon Rainforest (Brazilian Portuguese: Floresta Amazônica or Amazônia; Spanish: Selva Amazónica or Amazonía g. the Guianan Gnatcatcher). The North American species nest in bushes or trees, but the breeding behavior of several of the Neotropical species is essentially unknown. In Biogeography, Neotropic or Neotropical refers to one of the world's eight terrestrial Ecozones This ecozone includes South and Central America the

A species new to science, the critically endangered Iquitos Gnatcatcher Polioptila clementsi, was first described in 2005. This is the parent page for a series of pages listing bird species new to science described since 1900 Organisms with a conservation status of critically endangered have an extremely high risk of becoming extinct The Iquitos Gnatcatcher Polioptila clementsi is a Gnatcatcher (Polioptilidae described as new to science in 2005 This species is a member of the Guianan Gnatcather Polioptila guianensis complex, which recently has been proposed split into three species (four w. UserPolbot. -->The Guianan Gnatcatcher ( Polioptila guianensis) is a species of Bird in the Polioptilidae the Iquitos Gnatcatcher), but not all authorities have accepted this (e. g. SACC). The American Ornithologists' Union ( AOU) an ornithological organization in the USA. Furthermore, other groups should possibly be split, notably the Tropical Gnatcather Polioptila plumbea and Masked Gnatcather Polioptila dumicola complexes, but at present scientific papers on these matters are lacking. The Tropical Gnatcatcher ( Polioptila plumbea) is a small active Insectivorous Songbird, which is a resident species throughout a large part The Masked Gnatcatcher ( Polioptila dumicola) is a small active Insectivorous Songbird, found in northern Argentina, Uruguay
