Audubon's illustration of nesting house wrens. The nesting habits do not seem to differ significantly between the northern and southern house wrens. They usually construct a large cup nest in various sorts of cavities, taking about a week to build. The nest is made from small dry sticks and is usually lined with a variety of different materials.
The house wren complex has been split into eight species: Northern house wren, Troglodytes aedon; Southern house wren, Troglodytes musculus; Cozumel wren, Troglodytes beani; Kalinago wren, Troglodytes martinicensis; St. Lucia wren, Troglodytes mesoleucus; St. Vincent wren, Troglodytes musicus; Grenada wren, Troglodytes grenadensis; Cobb's wren ...
An American study showed that nuthatch responses to predators may be linked to reproductive strategies. It measured the willingness of males of two species to feed incubating females on the nest when presented with models of a sharp-shinned hawk, which hunts adult nuthatches, or a house wren, which destroys eggs. The white-breasted nuthatch is ...
The southern house wren (Troglodytes musculus) is a very small passerine bird in the wren family Troglodytidae. It is found from southern Mexico to southern Chile and southern Argentina. The name troglodytes means "hole dweller", and is a reference to the bird's tendency to disappear into crevices when hunting insects or to seek shelter.
A few species, notably the Eurasian wren and the house wren, are often associated with humans. Most species are resident, remaining in Central and South America all year round, but the few species found in temperate regions of the Northern Hemisphere are partially migratory, spending the winter further south.

Nesting behavior is an instinct in animals during reproduction where they prepare a place with optimal conditions to nurture their offspring. [1] The nesting place provides protection against predators and competitors that mean to exploit or kill offspring. [ 2 ]
An oak titmouse removes a fecal sac – feces wrapped in a membrane – from its cavity nest. Many species, such as the western bluebird , carry fecal sacs some distance from the nest. An adult Eurasian blue tit collecting the fecal sac of a chick (just hatched, still naked and blind) to ensure the cleanliness of their nest.
The inside of a tree swallow nest A male gathering nesting material The tree swallow has high rates of extra-pair paternity, 38% to 69% of nestlings being a product of extra-pair paternity, and 50% to 87% of broods containing at least one nestling that was the result of an extra-pair copulation.
