Meet the bird
What kind of bird is the Eastern Bluebird?
Eastern Bluebirds are small thrushes of open fields with scattered trees, fences, and nest boxes. Males are vivid blue above with a rusty breast; females carry the same pattern in softer gray-blue and warm brown.
Male Eastern Bluebirds are vivid blue above with a rusty or brick-red throat and breast.
Where to look
Where can you find the Eastern Bluebird?
Look along fences and utility wires for an alert, upright bird scanning the ground. Bluebirds drop from a perch to catch an insect, then return to a visible lookout, making their behavior as useful as their color.
Listen in the field
What does the Eastern Bluebird sound like?
Listen for a short, soft, wavering song rather than a powerful whistle. This example is a male singing near a nest box, with some low-frequency background noise lightly filtered by the recordist.
