what do ducks eat when they aren fed by people with bread?”
They’re perfectly happy to eat corn, or bread offered by humans, but in general, in the wild, are more or less omnivores–with limitations from their size and habitats. I grew up visiting my grandparents at the Lake of the Ozarks, several times a year, and feeding the local ducks was always fun. Dabbler ducks… As a group, the dabblers feed upon a variety of water plants: forest mast such as oaks, ash, and sweetgum; many water and land animals from insects to clams; and the seeds of many farm crops, grasses, and weeds. Diving ducks… Diving ducks feed mainly on aquatic foods, but there is a great diversity among species. For the most part, redheads and canvasbacks eat plants. Scaup eat both plants and animals. Maritime divers feed mostly on animals.
