Xenerpestes singularis
The Equatorial Greytail (Xenerpestes singularis) is a small, enigmatic passerine bird, measuring 14-16 cm in length and weighing a modest 18-22 grams. Its plumage is subtly beautiful, featuring an overall drab olive-grey dorsum that fades to a paler, greyish-white on the underparts. The most distinctive field mark, and the source of its common name, is its long, graduated tail, which is dark grey with fine, inconspicuous pale barring on the outer rectrices, often subtly fanned during foraging...
Found exclusively in humid, primary montane cloud forests and submontane rainforests, typically at elevations between 800 and 1,800 meters.
Primarily insectivorous, feeding on small arthropods such as beetle larvae, spiders, caterpillars, and ants, meticulously gleaned from bark, epiphytes, and dense foliage.
A diurnal species, the Equatorial Greytail is typically solitary or encountered in quiet pairs, often roosting singly in dense foliage. Its foraging strategy is highly specialized: it methodically gleans small arthropods from tree trunks, branches, and epiphytes, probing crevices with its chisel-...
The Equatorial Greytail is a resident species with a fragmented distribution across the humid montane forests of the Neotropics. Its primary range includes western Colombia, specifically the Chocó region and the Western and Central Cordilleras, extending into eastern Panama, particularly the Dari...
