Adult bringing food for young (note begging calls) House Wren peering out from a nesting box Depending on the exact population, the northern house wrens' clutch is usually between two and eight red-blotched cream-white eggs, [ 25 ] weighing about 1.4 g (0.05 oz) each and measuring c.17 and 13.4 mm (0.67 and 0.53 in) at the widest points.
The house wren complex has been split into eight species: Northern house wren, Troglodytes aedon; Southern house wren, Troglodytes musculus; Cozumel wren, Troglodytes ...
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.
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 Carolina wren was first described under the name of Sylvia ludoviciana by John Latham in 1790. [3] [note 1] Louis Pierre Vieillot considered all wrens under the genus Troglodytes and called the Carolina wren Troglodytes arundinaceus, but placed it subsequently in a separate genus Thryothorus (initially misspelled Thriothorus) [2] that he created in 1816.
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 ]
The house wren occurs widely in both tropical and temperate lowlands, but is now split into several species. Until recently, the hardy winter wren was believed to have a wide distribution in North America , Europe , Asia and North Africa , but it has recently been split into three species, of which the Eurasian wren is the only wren of any ...
House wrens compete with Bewick's wrens for similar nesting sites. House wrens will destroy both the nests and eggs of Bewick's wrens. [2] The reforestation of once open land has also negatively impacted the eastern Bewick's wrens. [2] In California, habitat loss due to development has impacted the Bewick's wren.
