Premigrational Movements and Behavior of Young Mallards and Wood Ducks in North-Central Minnesota,

Abstract

Movements and behavior of 89 young mallards (Anas platyrhynchos) and 48 young wood ducks (Aix sponsa) were monitored in north-central Minnesota in late summer and fall, 1972-74, with telemetry, visual observation, and aerial surveys. Initial flights of both species were confined to the natal (brood) marsh. First flights away from the natal marsh occurred in the third week after fledging in both species. As young mallards and wood ducks grew, their daytime use of the natal marshes decreased in an irregular pattern as both species began daily flights between day and night use areas.
