All but one of the 80-odd species of wren are found only in the New World, the exception being the widespread and familiar Eurasian Wren (Troglodytes troglodytes), found in Eurasia and parts of north Africa. They are small insectivores with fine bills, often somewhat decurved, and mostly brown or rufous plumages, sometimes with areas of black and white. Not all have the short cocked tail of Eurasian Wren: some have longer tails and a few are almost tailless. The tail feathers are generally barred.
