Troglodytidae: The true wrens are members of a mainly New World passerine bird family Troglodytidae containing 79 species. A troglodyte means a cave-dweller, and wrens get their scientific name from the tendency of some species to forage in dark crevices. They are mainly small and inconspicuous except for their loud songs. These birds have short wings and a thin down-turned bill. Several species often hold their tails upright. All are insectivorous.
Only one species, Troglodytes troglodytes, known as the Winter Wren in North America, occurs in the Old World, where it is commonly known simply as the Wren. |
