Carolina wren with nest

Description:

The Carolina Wren is a small but chunky bird with a round body and a long tail that it often cocks upward. The head is large with very little neck, and the distinctive bill marks it as a wren: long, slender, and downcurved. Nests of the more domestically-inclined wrens have been reported in a great variety of nooks and crannies in, about, or under buildings of various kinds, under bridges, or in holes in any structure such as a porch, fence-post, flowerpot, tree, house or barn. Almost any kind of receptacle may offer an acceptable nesting site. Pairs may mate for life.

Habitat:

Resident in the eastern half of the USA, the extreme south of Ontario, Canada, and the extreme northeast of Mexico. Seen in my yard.

Notes:

This wren has built a nest in my newest bluebird box.
