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.

Flight Pattern

Slow flight with shallow wing beats.

● Range & Habitat: Western Bluebird: Breeds from southern British Columbia and western Alberta south to Baja and east throughout the mountains of the west to eastern New Mexico and extreme western Texas. Spends winters throughout most of its breeding range, although northernmost populations usually withdraw slightly southward. Preferred habitats include open woodlands and pastures where old trees provide nest sites.

4 and 6 letter alpha codes

The four letter common name alpha code is is derived from the first two letters of the common first name and the first two letters of common last name. The six letter species name alpha code is derived from the first three letters of the scientific name (genus) and the first three letters of the scientific name (species). See (1) below for the rules used to create the codes..

Four-letter (for English common names) and six-letter (for scientific names) species alpha codes were developed by Pyle and DeSante (2003, North American Bird-Bander 28:64-79) to reflect A.O.U. taxonomy and nomenclature (A.O.U. 1998) as modified by Supplements 42 (Auk 117:847-858, 2000) and 43 (Auk 119:897-906, 2002). The list has been updated by Pyle and DeSante to reflect changes reported by the A.O.U from 2003 through 2006.
