Mating and Feeding Behavior of the Northern Shoveler

10,000 Birds

They are dabbling ducks which feed by upending and, you guessed it, dabbling. Unlike most other dabbling ducks however, the Northern Shovelers strain aquatic vegetation, plankton, and tiny invertebrates through the comb-like edges of their shovel-shaped bill.
