Chestnut-breasted Wren Cyphorhinus thoracicus Scientific name definitions

Pairs or family groups of Chestnut-breasted Wren forage on or near the ground in humid montane forest of the Andes. They are difficult to observe in the dense understory, but give away their presence with raspy churr calls and a loud song. Two subspecies have been described, which are very similar in appearance, but these have notably different songs: the song of the northern dichrous is a short set of haunting whistles, but the song of the southern thoracicus also includes trills and squeaks.
