House wrens nest in tree cavities, such as old woodpecker holes. The female lays a clutch of 4 to 8 (usually 6) eggs, which she incubates for about 12 days. The chicks are altricial when they hatch, and are brooded by the female. Both parents feed the chicks, which fledge after 15 to 17 days. The chicks all leave the nest within a few hours of each other. After the chicks leave the nest, both parents continue to feed them for about 13 days.
