Буропоясничный тапакуло Scytalopus latebricola

Small, mouse-like bird found only at higher elevations in Colombia’s Santa Marta Mountains. Adult is gray with a bit of brown on the rump and lower underparts. Young birds are browner with dark barring and scaling. The only other tapaculo in range is Santa Marta Tapaculo, which has a white crown patch, occurs at lower elevations, and has a different voice. Song starts with several sharp notes, and then abruptly morphs into a harsh, rapid trill. Skulks in cloud forest understory, where it is normally hard to see well.
