Carolina wren

Its freely uttered song is a loud, clear two-syllabled whistle, in tone like the voice of the Carolina Wren or Cardinal.

The Carolina Wren is a bird of the woods, whose loud, musical whistles are among the most conspicuous of southern bird notes.

Now the Carolina Wren sings, ‘cheerily, cheerily, cheerily.’

The Carolina Wren frequents the undergrowth in thickets; he is the most nervously active of all the wrens.
