Life Cycle

Breeding season begins in early March, peaks from late April to mid-May, and extends to mid-July. The Carolina Wren nests in a variety of places including old woodpecker cavities, within upturned roots of a tree, at the base of trees, in nest boxes, in hanging plants, and even in a coat pocket or a kitchen pot if access is available. The nest is built of twigs, bark strips, and leaves, and lined with finer material. Four to eight (usually 5) eggs, which are whitish or pinkish in color and flecked with browns and purples, are laid and incubated by the female for 12-14 days. The altricial young hatch and leave the nest after 12-14 days.

Habitats of the Carolina Wren include brushy areas usually near deciduous forests, but these birds are highly adaptable, using residential areas with available dense shrubby areas. The Carolina Wren forages near the ground, searches for insects and insect larvae from the branches and leaves of shrubs, and will also eat seeds from the ground or vegetation.
