New York State Bird
Eastern Bluebird (common name)  Sialia sialis (scientific name) Overview The eastern bluebird is a small blue thrush with a soft, pleasant warbling song. It was designated the state bird of Missouri in 1927, and New York followed suit in 1970. Bluebird populations fell precipitously in the early 20th century because of competition from starlings and sparrows for nest holes. The male bluebird has blue wings and tail and a reddish-orange chest. The female is grayer with a lighter orange chest. Both males and females have a stocky body, a round head, and a short black bill. Their diet consists of insects in spring and summer, fruit and berries in fall and winter.

During the courtship season the male bluebird will sing while quivering its wings. HABITAT Open woodlands, farmlands, and orchards. Range: East of the Rocky Mountains, north to southern Canada and south to Central America. Migration: Non-migratory populations live from southeastern Arizona south to Nicaragua. Populations in southern Canada are migratory, wintering in the southeastern United States. Some fly as far as 2,000 miles from western Manitoba to Texas.

He brings nest material to the hole, goes in and out, and waves his wings while perched above it. The female bluebird who accepts the male's invitation will then build the nest and incubate the eggs.
