Chestnut-breasted Nigrita Nigrita bicolor

An easily overlooked finch that can sit unnoticed low in the shadows of forest, forest edge, and farmlands. Bicolored in appearance, with dark reddish underparts and face and a gray crown, back, wings, and tail. Sometimes encountered in small groups or mixed-species flocks, and will venture into the canopy. Co-occurs with and sometimes flocks with other species of nigrita, but distinguished from them by its dark reddish undersides combined with its small size. Song is variable, sometimes consisting of four wavering whistles that rise and then fall on the last note: “where are you, there?” Also gives a rising and falling “twee-teer” in combinations of varying length, in addition to harsh chattering notes.
