| Xenops rutilans Temminck, 1821 |
The Streaked Xenops, Xenops rutilans, is a passerine bird which breeds in the tropical New World from Costa Rica and Trinidad south to Bolivia and northern Argentina. It is a member of the South American bird family Furnariidae.
The Streaked Xenops is typically 12.2 cm long, weighs 12.6 g, 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. Sexes are similar. Visually inconspicuous, it is easier located by its chattering call, a series of 5 or 6 metallic zeet notes.
It is found in wet forests in foothills and mountains between 600-2,200 m altitude, and will utilize secondary forests and opened-up growth.[1] The Streaked Xenops is often difficult to see as it forages on bark, rotting stumps or bare twigs.[1] It feeds on arthropods, including the larvae of wood-boring beetles. It moves in all directions on the trunk like a treecreeper, but does not use its tail as a prop. It regularly joins mixed-species feeding flocks.
The Streaked Xenops builds its nest by simply placing a few stems and roots in a hole 1.5-4.5 m high in a tree. The normal clutch is two white eggs, incubated by both sexes. This species is a resident breeder in forest habitats.
