Description

The cinnamon screech owl is a small screech owl, long and weighing . Adults have a warm brown

facial disc In ornithology, the facial disc is the concave collection of feathers on the face of some birds—most notably owls—surrounding the eyes. The concavity of the facial disc forms a circular paraboloid that collects sound waves and directs those ...

. The wings and tail are cinnamon with brownish and blackish bars. Their undersides are a rich cinnamon buff with some warm brown wavy marks on the throat and chest. No juvenile has been described.

s and probably small vertebrates.

Breeding

The cinnamon screech owl's breeding season, nest, and eggs have not been described. It is assumed to nest in tree cavities like others of its genus.

Vocalization

The cinnamon screech owl's primary (territorial) song is "a flat series of hoots" similar to but faster than that of the rufescent screech owl. Its aggressive song is described as "''pu-pu-pu-pu-pu pu pu pu pu pu''" that starts fast, abruptly slows, and rises in pitch.
