IDENTIFICATION OF NORTHERN AND LOUISIANA WATERTHRUSHES

Abstract

Separation of the Northern Waterthrush (Seiurus noveboracensis) from the Louisiana Waterthrush (S. motacilla), both in the field and in the hand, presents difficulties that are not adequately treated in either the popular or technical ornithological literature. The purpose of this article is to analyze the published identifying characters in light of my own field and museum experience.
