Diving duck

A waterfowl that submerges to find food, including pochards, scaup, and sea ducks. Its legs are set farther back than those of dabbling ducks, aiding underwater propulsion.

Foot-propelled diving: Underwater locomotion powered by alternating strokes of the feet. Diving ducks use their webbed feet to propel themselves while submerged.
Anatidae: The bird family comprising ducks, geese, and swans. Diving ducks are members of this larger waterfowl family.
Waterfowl migration: Seasonal movement by ducks, geese, and swans between breeding and nonbreeding areas. Many diving ducks travel long distances between breeding lakes and wintering waters.
Common pochard: A Eurasian diving duck of lakes and wetlands, recognizable by the male’s chestnut head. It exemplifies freshwater pochards and their wetland habitats.
Lead poisoning in waterfowl: Illness or death in waterbirds after they ingest lead ammunition or fishing tackle. Diving ducks may swallow lead shot while feeding on lake bottoms.
Duck feet: Webbed feet adapted for swimming, steering, and movement on land. Their rear-set legs and broad feet provide powerful underwater thrust.
Aythyini: A tribe of diving ducks that includes pochards and scaups. This group contains many familiar freshwater diving ducks.
Wetland conservation: The protection and restoration of wetlands and their ecological functions. Freshwater diving ducks depend on wetlands for breeding and feeding.
Greater scaup: A northern diving duck that winters in coastal waters and breeds near Arctic lakes. Its seasonal shift links inland breeding grounds with marine feeding areas.
Avian influenza: Influenza A viruses that infect birds and sometimes spread among wild waterfowl. Migrating and congregating waterfowl can carry avian influenza between regions.
