These birds have a length of 5.75 in (15 cm) and a weight of 20 g (0.7 oz). Their wings could range from 7.5 in (19 cm).


Carolina wrens are ground-feeders. They consume a wide range of insects and spiders when they come upon them. With their bills, hunt for food beneath brush piles, under a log and rotting wood heaps, under overturned roots, under bark, and along marsh banks.


In addition to brushy clearcuts, they also live in forested swamplands. Moist woods are favored, and moderate to thick shrub or brush cover is required. Farmyards, woods, suburban gardens, live oak and palmetto hummocks, solitary clusters of trees on grasslands, and old sheds are all examples of Carolina wren habitat.


Diurnal and nonmigratory, breeding pairs defend territories year-round with songs and cries. Carolina wrens are land-based. They spend much of their time hopping along the ground, at astonishing speeds. They can fly short distances but rarely do so. Their wings will let them leap over tree trunks and garbage piles. Carolina wrens may also climb trees to establish nests or eat.
