Song & Call Comparison
Barn Owl
An eerie, drawn-out rasping shriek 'shreeeeee' — not a hoot. Also gives hissing, snoring, and bill-snapping when disturbed. Chicks call with a persistent rasping hunger call.
Common Starling
A complex mimic: rattles, whistles, clicks, and squeaks mixed with imitations of other birds. Song is a continuous medley. Also gives harsh 'scheer' alarm and chattering.

About These Birds
Barn Owl
The barn owl has the most asymmetrical ears of any owl, giving it the finest auditory localization ability in the animal kingdom. It can catch prey in complete darkness using sound alone. The barn owl's distinctive heart-shaped face acts as a parabolic dish, funneling sound to its offset ears.
Common Starling
Estorninho-malhado (Sturnus vulgaris) — 19-22 cm. Distribuído pela Europa e Ásia, introduzido na América do Norte, Austrália e África do Sul. Plumagem negra com reflexo metálico verde e roxo, com pontas brancas no inverno. Voo em bandos enormes (murmuração) é espetáculo notável. Excelente imitador. Omnívoro adaptável a ambientes urbanos e agrícolas.
