Calvert Cliffs in early spring…..
The bobbleheads, er, buffleheads, paid us a visit as we hung out on the beach searching for fossils. They bob on the waves, then dive for food.
Bufflehead dive for aquatic invertebrates, crustaceans, and mollusks. They typically swallow their food while still underwater. Dives last on average about 12 seconds and rarely more than 25 seconds, typically staying on the surface another 12 seconds or so before diving again. Bufflehead forage in open, shallow water over sparse submerged vegetation or over mudflats that would be exposed at low tide. On freshwater they mostly eat damselfly and dragonfly larvae, midge larvae, water boatmen, mayfly larvae, caddisfly larvae, large zooplankton such as amphipods, and snails and clams in winter. They eat some plant matter in fall and winter, mainly seeds of pondweeds and bulrushes. In saltwater, Bufflehead eat shrimp, crabs, amphipods, isopods, snails, mussels, herring eggs, sculpins, and ratfishes. Downy ducklings sometimes dabble at the surface rather than diving.
