On ponds and marshes where it breeds, the pied-billed grebe advertises its presence with loud, barking calls. It eats small fish, crustaceans, and aquatic insects but is especially fond of crayfish, which it crushes easily with its stout bill. When alarmed, this grebe often sinks slowly into the water, resurfacing out of sight among the reeds. But it can also dive with amazing speed, a habit that has earned it the nickname “hell-diver”. It is also called the “dabchick” in some areas. It is the most common nesting grebe in the east.
