The Bluebird (one word) isn't the only blue bird. It isn't even
the bluest. Female Eastern Bluebirds often don't look blue at all unless in flight. Only 2% of North American Species have blue feathers. The birds most commonly confused with bluebirds by novices are the Jays and the Indigo Bunting. (Tekiela) Small cavity nesters that are blue or blue-ish include Tree Swallows, Violet-Green Swallows and Purple Martins. Indigo Buntings are very blue, and are often confused with bluebirds. Other small to medium-sized native birds with blue bodies include:
Jays: Blue Jay, Florida Scrub-Jay, Mexican Jay, Pinyon Jay, Steller's Jay, Western Scrub-Jay
Swallows: Bahama Swallow, Barn Swallow, Tree Swallow
Warblers: Black-throated Blue Warbler, Cerulean Warbler
Here's an alphabetic list of North American species with blue or blue-ish bodies, sorted by common name. (Notice several have "cyan" in their scientific names.) Click on any photo (from Wikimedia Commons) for a larger view. For more ID tips, distribution maps and to listen to songs, see Cornell, Patuxent, or What Bird online guides, or get a good birding ID book. ( I am not a birder by any means! All I can recognize are small cavity nesters, so don't bother contacting me for help.)
