Louisiana Waterthrushes
The Louisiana Waterthrush, Seiurus motacilla , is a New World warbler.
Distribution / Range
It breeds in eastern North America from southernmost Canada and south through the eastern USA, excluding Florida and the coast.
It is migratory, wintering in Central America and the West Indies. This is a rare vagrant to the western USA.
Description
The Louisiana Waterthrush has a plain brown back and white underparts streaked with black. The flanks and undertail are buff. There is a strong white flared supercilium (line above eye), and the legs are bright pink. All plumages are similar, but young birds have buff underparts rather than white.
The only confusion species is the closely related Northern Waterthrush, Seiurus noveboracensis, which has white flanks and undertail and duller pink legs.
Breeding / Nesting
The breeding habitat is wet woodlands near running water. Louisiana Waterthrushes nest in a rock crevice or amongst tree roots, laying 4-6 eggs in a cup nest.
Feeding / Diet
These birds are terrestrial feeders, seeking insects, molluscs and crustaceans amongst the leaf litter.
Song / Vocalization
The song is a musical series of descending notes followed by a warble. The call is a hard chink.
