Spillmann's tapaculo (Scytalopus spillmanni) is a species of bird in the family Formicariidae. It inhabits the Andes of Colombia and Ecuador.[1]
The Spillmann's tapaculo was previously considered a subspecies of brown-rumped tapaculo (Scytalopus latebircola) but was elevated to species rank due to differences in their vocalizations.[2] It and chusquea tapaculo (S. parkeri) form a superspecies.[3] The population in Colombia's eastern Andes might be different enoung to be a subspecies.[4]
Spillmann's tapaculo is 12cm (05inches) long. Males weigh 21to and females 20to. The male is blackish gray above with a dark brown rump. It is lighter gray below with tawny to cinnamon flanks and vent area. Some females are like the male, but most have the upperparts heavily washed with brown and an orange lower belly. The juvenile is brown above and dusky below, with barring above and below.[4]
Spillmann's tapaculo is found in all three Andean ranges of Colombia and south into Ecuador. In the west it extends to Cotopaxi Province and in the east into Morona-Santiago Province. It inhabits the undergrowth of humid montane forest and is especially partial to Chusquea bamboo. It ranges generally from 1900to but is found locally up to 3500m (11,500feet) and as high as 3700m (12,100feet) in western Napo Province, Ecuador.[4]
Spillmann's tapaculo forages on the ground or near it, mostly for small insects.[4]
Little is known about the breeding phenology of Spillmann's tapaculo, but it probably breeds throughout the year.[4]
