Myrmotherula ignota
The Moustached Antwren (Myrmotherula ignota) is a diminutive and often cryptic member of the Thamnophilidae family, characteristic of the dense understory of humid tropical forests. Measuring a mere 9-10 cm (3.5-4 inches) in length and weighing just 7-9 grams, it is a testament to the intricate biodiversity of its South American habitat. Males are distinctive with a slate-gray head, prominent black moustachial stripe, black streaking across a whitish breast, an olive-brown back, and blackish ...
Found in the dense understory and mid-story of humid evergreen primary and secondary forests, often favoring areas near water or swampy lowlands, at elevations typically up to 1,200 meters.
Primarily insectivorous, feeding on small arthropods such as insects (caterpillars, beetles, ants) and spiders, which they glean from foliage and small branches.

They primarily employ a gleaning foraging strategy, meticulously picking small insects and spiders from the undersides of leaves, twigs, and small branches, oft...
The Moustached Antwren has a discontinuous distribution spanning parts of Central and northern South America. Its primary range includes eastern Panama, extending into northern and western Colombia, and further south into western Ecuador and extreme northwestern Peru. The species is resident thro...
