Hutton's Vireo

Hutton's vireo (Vireo huttoni) is a small songbird. It is approximately 5 inches (12–13 cm) in length, dull olive-gray above and below. It has a faint white eye ring and faint white wing bars. It closely resembles a ruby-crowned kinglet, but has a thicker bill, blue-gray legs, and is slightly larger in size. Its most common song is a repeated chu-wee, or a chew, but will have other variations. Its call is a mewing chatter. It is found from southern British Columbia in Canada to central Guatemala in Central America. Recent DNA studies suggest this species may be split into at least 2 different species, with coastal Pacific birds showing enough genetic variation when compared to interior ones.
