Jenny Wren (Troglodytes troglodytes)

The Male Wren builds several nest but the female adds the lining to the nest she decides to use. In proportion to its size, the wren has the loudest song of any British bird. Wrens will nest communally in winter, with as many as 10 birds spending the night together in a single nestbox. The family name for the wrens is Troglodytidae, which means cave dweller.
