Carolina Wren
Thryothorus ludovicianus
Troglodytidae
Small, rich rusty-brown, with a bold white eye-stripe and an outsized voice. Carolina Wrens are pound-for-pound one of the loudest songbirds in North America — a bird the weight of two nickels can carry a two-hundred-yard clear morning song over a suburban lawn. Insectivorous nearly year-round; almost never eats seed.
How to spot one.
4.5–5 inches, plump body, upturned tail
Warm cinnamon-rufous back and tail
Prominent white stripe above the eye
Buff belly, pale throat
Long slightly downcurved bill
What it sounds like.
Loud ringing 'tea-kettle, tea-kettle, tea-kettle' — usually attributed to the male, but the female sings a duet response.
How it lives.
Nests in unusual places — hanging baskets, mailboxes, garage shelves, coat pockets on a hook. Both sexes sing. Ranges have crept northward with warmer winters; hard winters can knock back NJ populations significantly. Prefers dense shrub cover.
