The House Wren (Troglodytes aedon) is a small bird, only about 4.5 inches, that is overall greyish brown. Its short tail is often held in a cocked pose over the back.
House Wrens are found throughout the USA and in parts of southern Canada. They are seen in residential areas, parks, and woodland edges. They are cavity nesters and will lay their clutch of from 5 to 8 eggs in a feather lined mass of twigs and sticks placed in a nest box or tree hole or other cavity. The eggs are off white and spotted with brown. The incubation period is from 14 to 17 days.
It may be small for its size, but when competing for a nesting spot, it can be quite aggressive, tossing out its competitors whole nest, including any inhabitants.
The House Wren belongs to the family Troglodytidae, of which there are 75 species in the Western Hemisphere. They feed on insects.
