Biglišući tapakulo Scytalopus vicinior

A standard Scytalopus tapaculo: plain dark gray with browner flanks and rump. Acts like a mouse, scurrying around on or near the ground within montane forest. Very difficult to see. Restricted range on the west slope of the Andes in Colombia and Ecuador. Occurs from around 1,250–2,000 m, which is higher than Choco Tapaculo but lower than Spillmann’s Tapaculo (but some overlap). Far more often heard than seen. Listen for fairly rapid trill with distinct notes; notably slower than Spillmann’s.
