The lesser scaup is classified as which type of waterfowl?

The lesser scaup is classified as a diving duck, which is a group of waterfowl capable of diving underwater to forage for food. These ducks typically dive to obtain aquatic plants, invertebrates, and small fish, which comprise a significant part of their diet. Unlike dabbling ducks, which feed primarily on the water's surface and in shallow areas, diving ducks such as the lesser scaup are adapted for deeper water, using their strong bodies and powerful legs to help propel themselves underwater. This behavioral adaptation is crucial for their survival in various habitats where they seek food beneath the surface.

The classification of diving ducks includes several species that share this feeding strategy, distinguishing them from dabbling ducks and other groups, such as perching or swimming ducks, which do not possess the same diving capabilities.
