Striated Antthrush Chamaeza nobilis

Chunky, brown-and-white bird of lowland rainforest. Brown above, white below with extensive brown streaking. The facial pattern is attractive with white eyebrows and a dark brown mustache. Forages on the ground of tall, mature rainforest. Very quiet during the dry season; it usually starts singing more frequently with the onset of the rainy season. Its song is a distinctive, long series of low hoots that accelerates from a pace of one note per second to ten notes per second over about eight seconds. May sometimes give a series of slow, rising hoots at the end of its song.
