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. [1]
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. [2] [3] [4]
The Guianan gnatcatcher is 10 to 11 cm (3.9 to 4.3 in) long and weighs 5 to 7 g (0.18 to 0.25 oz). The male's head, back, and breast are bluish gray. It has a broken white eye ring. The innermost feathers of its tail are black and the two outermost white. Its throat and belly are white. The female is similar but a paler gray and has a white supercilium. [4]
The Guianan gnatcatcher is found in the Guianas and adjoining Brazil south to the Amazon River. [5] Its range might also extend westward into eastern Venezuela. [1] [4] It inhabits the borders and canopy of humid primary forest, savanna forest, and dryland forest. [4]
The Guianan gnatcatcher's diet has not been documented but is assumed to be arthropods like that of other Polioptila gnatcatchers. It actively forages as part of mixed-species flocks. [4]
The Guianan gnatcatcher's breeding phenology is essentially unknown, but "A male was observed feeding a fledgling on 27 November 1984 in French Guiana". [4]
The Guianan gnatcatcher's song is "fairly simple...repeated high notes" . [4]
The IUCN has not assessed the Guianan gnatcatcher separately from the larger species complex that predated the 2019 splits. That complex was assessed as of Least Concern. [6] "The species’ ecoregion of primary occurrence, Guianan moist forest, not considered to be at serious risk, given its current and projected conservation status." [4]
The Gnatcatchers are a family of small passerine birds called Polioptilidae. The 21 species occur in North and South America. 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.
