Small, cryptically patterned, yellow-eyed owl of tropical lowland forest from Panama to Ecuador. Tends to stay well hidden in the understory. Cannot be identified readily by sight, but it is the only screech-owl throughout most of its range and within its habitat. Song is a purring trill that can easily be mistaken for the purring of a toad or insect. Plumage varies from grayish brown overall to reddish.
