Field Notes
Description:
The Carolina Wren (Thryothorus ludovicianus) is a common species of wren, resident in the eastern half of the USA, the extreme south of Ontario, Canada, and the extreme northeast of Mexico. A distinct population in the Yucatan Peninsula of Mexico, Belize and extreme north of Guatemala is treated either as a subspecies Thryothorus ludovicianus albinucha, or as a separate species, White-browed Wren Thryothorus albinucha. Following a 2006 review, these are the only wrens remaining in the genus Thryothorus. T. ludovicianus is the state bird of South Carolina; its specific name ludovicianus means "from Louisiana".
Typically 14 cm long (6–7 in) and about 20 g in weight, it is a fairly large wren; among the United States species it is second largest after the Cactus Wren. The upperparts are rufous brown, and the underparts a strong orange-buff, usually unmarked but faintly barred on the flanks in the southwest of the range. The head has a striking pure white supercilium (eyebrow) and a whitish throat. The race albinucha is duller brown above and has additional white streaking on the head.
It is easiest to confuse with the Bewick's Wren, a fairly close relative, which differs in being smaller but with a longer tail, grayer-brown above and whiter below. The Carolina and White-browed Wrens differ from the House Wren in being larger, with a decidedly longer bill and hind toe; their culmen has a notch behind the tip.
Habitat:
The Carolina Wren is sensitive to cold weather. Since they do not migrate and stay in one territory the northern populations of Carolina wrens decrease markedly after severe winters. Because of this sensitivity to weather, gradually increasing temperatures over the last century may have been responsible for the northward range expansion seen in the mid-1900s.
Populations in Canada and the northern half of the US experience regular crashes following severe winters, but their high breeding productivity soon results in a return to higher numbers. These birds are generally permanent residents throughout their range and defend territory year round; some birds may wander north after the breeding season.
They eat insects, found in leaf litter or on tree trunks; they may also eat small lizards or tree frogs. In winter, they occasionally eat seeds, berries, and other small fruits.
