The winter wren nests mostly in coniferous forests, especially those of spruce and fir, where it is often identified by its long and exuberant song. Although it is an insectivore , it can remain in moderately cold and even snowy climates by foraging for insects on substrates such as bark and fallen logs.
Nest cavities are usually a few meters above ground at most, [21] [22] but occasionally on cliffs as high up as 15 m (49 ft) and more at least in southern populations [verification needed]; they may be natural or man-made, often using bird houses. Northern house wrens are feisty and pugnacious animals considering their tiny size.
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 ...

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.
Like other wrens, they are elusive as they hunt for small insects and spiders, but they readily reveal their positions through their loud songs. These are territorial birds, but the tiny winter wren will roost communally in a cavity in cold weather to help conserve heat.
The name "Wren's Nest" came from his discovery of a family of wrens living in the mailbox in the spring of 1895. [5] After several years of correspondence, Indiana poet James Whitcomb Riley visited Harris at Wren's Nest in 1900. Harris's children were especially interested in Riley and nicknamed him Uncle Jeems. [6]
Additionally, snakes and raccoons are known to threaten their nests. These predators often target the eggs or fledglings, making early life particularly dangerous for the gnatcatcher. In order to avoid predators, gnatcatchers rely on their excellent camouflage and the dense vegetation of the coastal sage scrub to hide from potential threats.
