What to Watch for


Bluebirds are about 7 inches long.


The male is bright blue with white undersides and a rust-colored breast. The female is grayish blue, but otherwise similar to the male.

Where to Watch

Bluebirds nest in cavities in standing dead trees and in nesting boxes.
Nesting boxes are set on posts five to six feet off the ground and come in pairs (one for the bluebirds, the other for the competition). Bluebirds eat insects, seeds, and berries, so look for them in fields, meadows, and orchards.

What to Listen for

A musical "chur-wi" or "tru-ly".

When to Watch

Bluebirds may be present year-round. Most migrate to southern states in the fall, but they will winter in New York State if they can find enough food.
