: Non-breeding. on freshwater late May-Aug, mostly single, presumably unpaired males.
: on freshwater mid Mar-mid Apr when often in pairs, with to mid May and again late Oct-early Dec. on inshore saltwater.
: Dec-Feb, mostly single males wintering with flocks of Mallards and American Black Ducks sustained with supplemental feeding.
