Song & Call Comparison
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.
Peregrine Falcon
A harsh, wailing 'kak-kak-kak-kak' repeated rapidly in defense of the nest. Alarm call is a long screaming 'raaak'. Mostly silent away from breeding sites.
Geographic Range & Migration

About These Birds
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.
Peregrine Falcon
The peregrine falcon is the fastest animal on Earth, reaching speeds over 389 km/h during its characteristic hunting stoop. Like the bald eagle, peregrines suffered dramatic declines from DDT but have recovered through intensive conservation programs. They have adapted remarkably well to urban environments.
