Taxonomy and systematics
editThe Para gnatcatcher is monotypic It was formerly treated as a subspecies of the Guianan gnatcatcher (Polioptila guianensis) but since mid-2019 has been considered a separate species based on differences in morphology and vocalization.[2][3][4]
Description
editThe Para gnatcatcher is 10 to 11 cm (3.9 to 4.3 in) long and weighs approximately 6 g (0.21 oz). The male's head, back, and breast are mouse gray and the rest of its underparts white. There is minimal contrast between the throat, breast, and belly. The innermost feathers of its tail are black and the outermost white, with those between intergrading. The female is similar but has a paler face.[5]
Distribution and habitat
editThe Para gnatcatcher is found only in Brazil, in a broad band south of the Amazon River from its mouth southwest almost to northern Bolivia. It inhabits the borders and canopy of humid primary forest, mostly below 500 m (1,600 ft) elevation.[5]
Behavior
editFeeding
editThe Para gnatcatcher's diet is little known but is assumed to be arthropods like that of other Polioptila gnatcatchers. It actively forages in the canopy and sub-canopy.[5]
Breeding
editThe Para gnatcatcher's breeding phenology has not been documented.[5]
Vocalization
editThe Para gnatcatcher's song is "repeated high...notes, evenly delivered" [1].[5]
Status
editThe IUCN has not assessed the Para gnatcatcher. "Of the ecoregions occupied by this species, only one (Tocantins/Pindare moist forest) is considered to be at serious risk."[5]
