Carolina Wren - East End Chebeague Island, Maine - Capps Road - April 10, 2011 9:40am

from Cornell's allaboutbirds site: Singing one of the loudest songs per volume of bird, the Carolina Wren's "tea-kettle, tea-kettle, tea-kettle" is familiar across the Southeast. It is a common bird in urban areas, and is more likely to nest in a hanging plant than in a birdhouse.
