House Wren
The House Wren, Troglodytes aedon, is a small songbird of the wren family.
Adults are 11.5cm long and weigh 12g. They have brown or grey-brown upperparts with pale grey underparts; there are black bars on the flanks, wings and tail. They have an eye ring, a faint line over the eye, a short thin bill and pink legs.
There are regional variations in the appearance of this bird. The subspecies found on Tobago, T. a. tobagensis is larger and has much paler underparts than the mainland forms. Some of the tropical forms are sometimes considered a separate species, the Southern House Wren, Troglodytes musculus.
Their breeding habitat is semi-open areas from Canada to southernmost South America. This bird builds its large cup nest in various sorts of cavities, either natural or man-made, often using bird houses where they are available, and sometimes choosing unusual sites such as old shoes.
The female incubates the clutch of three to six red-blotched cream-white eggs for 14-15 days, and the naked young take another 16-19 days to fledge.
House Wrens are known to destroy the eggs of other birds nesting near their territory.
North American birds migrate to the southern United States and Mexico.
These birds forage actively in vegetation. They mainly eat insects, also spiders and snails.
This bird's rich bubbly song is commonly heard during the nesting season but not at all afterwards.
This bird may have been displaced somewhat in some northern parts of its range by the introduction of the House Sparrow but is still common and widespread throughout most of the two continents.
King Friday XIII, a puppet character on the American children's educational program, Mister Roger's Neighborhood (Public Broadcasting Corporation), had a wooden wren upon a stick that he often played with as a cherished toy. He even composed a short song about the little toy bird which utilized the scientific name (Troglodytes aedon) and would sing to it.
