Scaups, buffleheads, and goldeneyes are smaller diving ducks with unique markings and coloration.3. Habitat of Diving Ducks in Maryland
Diving ducks inhabit freshwater and saltwater environments, including lakes, rivers, bays, and marine estuaries. In Maryland, they are commonly found in areas such as the Chesapeake Bay, Patuxent River, and Assateague Island.4. Behavior of Diving Ducks
Diving ducks are excellent swimmers and divers, and they can stay underwater for up to 30 seconds. They use their wings to "fly" underwater and propel themselves down to find food. Male diving ducks perform courtship displays to attract mates, including head-bobbing, wing-flapping, and vocalizations.5. Feeding Habits of Diving Ducks
Diving ducks primarily feed on aquatic vegetation, mollusks, crustaceans, and small fish. They use their powerful bills to crush shells and break apart hard foods. During migration, diving ducks will also feed on agricultural crops in fields near their habitats.6. Migration Patterns of Diving Ducks in Maryland
Diving ducks in Maryland are migratory birds and typically spend their breeding season in the northern regions of North America, including Alaska and Canada. They migrate south during the fall and winter, with some species wintering in Maryland's coastal bays and estuaries.7. Threats to Diving Ducks in Maryland
