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.
Eastern Bluebird
A rich, melodious warbled 'chur-wi, tur-a-lee' song. Both sexes sing. Call is a soft, musical 'turee'. Song is gentle and flute-like, suggesting a small thrush. Given from exposed perch.

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.
Eastern Bluebird
The eastern bluebird is a beloved symbol of happiness in North America. Once declining due to habitat loss and competition from introduced species, populations recovered dramatically thanks to a massive citizen science nest box campaign. These gentle thrushes form loose winter flocks and huddle together in nest boxes during cold snaps.
