Cuzco Brushfinch

Brushfinches are typically medium-size sparrows, with long tails. Brushfinches are usually gray or olive in colour with a contrasting crown. Cuzco brushfinches are two-toned with a uniform dusky gray and a rufous crown. The center of the belly, as well as the other underparts, are lighter gray than the outside, which is dark gray and the rufous color extends to the nape. The crown is boarded by a black stripe extending from in front of the eyes until the gray auriculars. The tail and wings are blackish with the primaries margined slightly with a grayish external. Voice: The Cuzco brushfinch has complex series of high-pitched squeaks. It is described as "shrill trill followed by a chatter and tew-tew-tew swee swee". Their "dawn song" was defined as the varied phrases given at regular intervals by the male alone, mainly or only at dawn and is different than a duet call. They are also known to include loud drawn out notes.
