Red-breasted Merganser
(Mergus serrator)

These large diving ducks reach lengths of 26" (65 cm). The males have a solid black head with a greenish sheen, a white collar and a distinctive red-brown chest patch. The females have a gray back and a rust colored head. They feed almost exclusively on fish and have a specially adapted, spikelike, serrated-edge bill used to catch and devour fish. They are found in the Bay during winter.
