Abstract: The green-winged teal is the smallest of our ducks. It is widely distributed, nesting from Alaska to Newfoundland and from the norther tree limit to central California and Maine, and wintering from British Columbia and Newfoundland south to Venezuela. As interest in waterfowl increases and the supply becomes less certain, the idea of regulating harvest by species has increased. It becomes increasingly important therefore, to learn and describe the population characteristics of each of the game species. Because of the currently low population levels of important waterfowl species such as the mallard, black duck, canvasback and redhead, regulations governing the hunting of these choice species have been restrictive. Thus species like the green-winged teal become more important as sources of additional hunting opportunity, but despite its wide distribution and rank among the 20-odd species in the harvest, information is lacking about its status. The present work reports a study of the distribution, migration, hunting kill, survival, and status of the green-winged teal in the New World.
