zapata sparrow Torreornis inexpectata

A handsome species with subtle coloration. Its yellow belly shades to olive sides, and a largely gray face is topped by a rusty crown and met below by black-borded white throat. Often found in pairs low in foliage or on the ground. No similar species occur in its range. Calls include a rapid twittering “ti-ti-ti…,” a high thin, “tzi-tzi-tzi,” and a rapid series of ten or more buzzy trilling notes that descend in pitch and grow softer towards the end.
