South Carolina State Bird

South Carolina State Bird

Carolina Wren (common name) 
Thryothorus ludovicianus 
(scientific name)

Overview

A small brown bird, but one of the biggest of the wren family, the Carolina wren is a popular songbird. It was declared the state bird of South Carolina in 1948 (when it replaced the mockingbird). It is brown above, orangeish-brown below, faintly striped on the sides, with a white throat. The head has a white "brow" and its tail is usually cocked, pointing straight up. The Carolina wren is a relentless singer; its many calls include a loud "tea kettle, tea kettle, tea kettle" song, an alarm call, and a very harsh scolding call made to drive away intruders. The male and female sing different parts that are interwoven into one call so it sounds like a single bird singing. Males sing more loudly, and songs will vary by geographic region.
In warmer seasons the Carolina wren primarily eats insects and spiders, but it will also eat small lizards or tree frogs. In winter, they also eat seeds, berries, and small fruit. Nests are typically a bulky dome with a small entrance at the top although they will nest in holes in fence posts and nooks in barns, bridges and houses at heights of 10 feet (3m) or less. The bird’s modest beauty and beautiful songs are important factors in its popularity.
