Streaked xenops

Appearance

The streaked xenops is typically 4.8 in long, weighs 0.44 oz, and has a stubby wedge-shaped bill. The head is dark brown with a whitish supercilium and malar stripe. The upperparts are brown, becoming rufous on the tail and rump, and there is a buff bar on the darker brown wings. The underparts are white-streaked olive brown. Males and females looks alike. Visually inconspicuous, it is easier located by its chattering call, a series of 5 or 6 metallic ''zeet'' notes.

Habitat

It is found in wet forests in foothills and mountains between 2,000-7,200 ft ASL, and will utilize secondary forests and opened-up growth. The streaked xenops is often difficult to see as it forages on bark, rotting stumps or bare twigs; it moves in all directions on the trunk like a treecreeper, but does not use its tail as a prop. It feeds on arthropods such as the larvae of wood-boring beetles, but can also catch flying termites in mid-air. It joins mixed-species feeding flocks on a more or less regular basis depending on location, usually moving through the middle levels of the forest.

Reproduction

The streaked xenops builds its nest by simply placing a few stems and roots in a hole 5–15 ft high in a tree. The normal clutch is two white eggs, incubated by both sexes.
