[3] The white-faced nunbird is found on the east slope of the Andes from western Colombia through eastern Ecuador into northwestern and central Peru.

It inhabits the interior and edges of humid to wet forest and cloudforest, often on steep slopes and in ravines.

[3] The white-faced nunbird's breeding season has not been fully defined but it includes April and May.

It was a leaf-lined chamber at the end of a 38 cm (15 in) long tunnel in an earthen bank.

Both members of the pair dug the burrow, incubated the eggs, and fed the young.

Its calls are "a mournful, downslurred 'wuooooo' [and a] series of accelerating, then decelerating barking notes, 'pah pah-pahpahpapapapa-pah-pah-grr?'.
