Western Bluebird

Western Bluebird: Small thrush with deep blue hood and upperparts, crescent mark across upper back, red-brown breast, and white belly. Bill, legs and feet are black. Populations are declining due to competition for nest sites with European Starlings, Tree Swallows and House Sparrows.

● Song: "kew-kew-kew-kew-kew"

● Foraging & Feeding: Western Bluebird: Diet consists of insects, earthworms, spiders, and snails. Takes berries during winter. Often hunts from low perches, from which it drops down to the ground to capture prey; also catches flying insects.

● Breeding & nesting: Western Bluebird: Three to eight pale blue eggs are laid in a grass nest built in a tree cavity or woodpecker hole. Incubation ranges from 13 to 14 days and is carried out by the female.

● Similar species: Western Bluebird: Eastern Bluebird has red-brown throat and breast, white belly and undertail coverts, and blue back.
