Mottled ducks are typically geographically separated into two sub-species: peninsular Florida (Anas fulvigula fulvigula) and the western Gulf Coastal (WGC) (A. f. maculosa). Between 1975 and 1983, >1,200 mottled ducks were introduced to coastal South Carolina primarily from the WGC range. A late summer banding program was initiated in 2008 within the Santee Delta and the Ashepoo, Combahee, and Edisto Rivers Basin in South Carolina to estimate mottled duck survival and harvest probability. We acquired 3,594 banding and 525 recovery records of mottled ducks banded between 2008-2018. We...

Managers of public lands affording waterfowl hunting strive to provide quality hunting opportunities while supporting biological needs of birds during winter. Understanding responses by mallards (Anas platyrhynchos) to diurnal hunting activities would help shape hunt regimes that satisfy management goals. We examined use of a wildlife management area (WMA) in western Mississippi by 28 radio-marked female mallards when waterfowl hunting season was closed and during the season when none, half, or all of the WMA was hunted during two winters 2010-2012. The proportion of each day that mallards...
