Their bodies tend to be shorter than those of diving ducks. These ducks are found at larger deeper lakes, rivers and coastal areas. Their bodies are relatively long, with the legs further back to allow them to dive deeply for feeding. Because of their body shape, diving ducks must run across the water as they begin takeoff. These birds have an unusual serrated bill structure.
Mergansers are primarily fish eaters.
Sea ducks also belong to this tribe. These birds, as you can guess, spend much of their time in ocean waters. They are seldom seen on shore except during summer during the breeding season. There are 19 different species of waterfowl represented in the lab today. Your goal is to be able to identify them - to learn their names and distinguishing characteristics.
