Western Bluebird

Sialia mexicana -- Fairly common. Like other bluebirds, this species migrates by day, and generally is found in small flocks outside the nesting season. They stopped by for some eats and a drink. Pretty birds. The usual song is a 3-fold or double whistle; a simple call note is typical. A more varied song is heard at dawn. Come back again.
