Tacarcuna warbler

The Tacarcuna warbler (Basileuterus tacarcunae) is a species of bird in the family Parulidae. Prior to 2012 it considered conspecific with the three-striped warbler, and the black-eared warbler.

Description
The Tacarcuna warbler measures 13 cm in length. It is mostly olive-brown with a buffy belly and underparts. It has distinct black and white striping on the head and a dark cheek. Male and female three-striped warblers have similar plumages.

Their song is a rapid series of squeaky chirps.

Distribution and habitat
It is found from eastern Panama to northwestern Colombia. Its natural habitats are subtropical or tropical moist montane forests and heavily degraded former forest. The Tacarcuna warbler typically forages on the ground, especially near riparian areas.
