The northern waterthrush Parkesia noveboracensis is one of the larger New World warblers and one of the Nearctic-Neotropical migratory songbirds. It breeds in the northern part of North America in Canada and the northern United States including Alaska. This bird is migratory, wintering in Central America, the West Indians and Florida, as well as in Venezuela, Colombia and Ecuador. It is a very rare vagrant to other South American countries and western Europe. The northern waterthrush is a large New World warbler and not a thrush, despite the name. The only species bird watchers confuse with the northern waterthrush is the closely related Louisiana waterthrush Parkesia motacilla, which has buff flanks, a buff undertail, and bright pink legs. The Louisiana waterthrush also has a whiter throat with fewer streaks. More subtle clues include smaller size and smaller bill, a narrower and darker eye-line, and different call note and habits. Both waterthrush species walk rather than hop, and seem to teeter, since they bob their rear ends as they move along. The breeding habitat of the northern waterthrush is wet woodlands near water. It nests in a stump or among tree roots where it lays three to six eggs, cream- or buff-colored, with brown and gray spots. These eggs are laid in a cup nest constructed of leaves, bark strips, and rootlets. The northern waterthrush is a terrestrial ground feeder eating insects, mollusks, and crustaceans found amongst leaf litter.
