A wren is a small and compact bird, with a flat head and fairly long, curved beak. It is also short-winged, often keeping its longish tail either cocked above the line of the body or slightly drooped. Wrens are primarily insect eaters, but they will also eat some fruits and seeds. House Wrens build nests of twigs and grass. They lay approximately 6 to 7 white eggs. The incubation time is 12 to 15 days. Wrens will lay 2 broods in the nesting season (typically April to July). The male House Wren builds several nests and the female chooses which nest she prefers. The other nests may be used by the male to raise a second brood with another female and will remain in place to discourage other male wrens from nesting in the same territory.
