The coyote eats pelicans, as do cats and humans. Smaller mammals and birds, such as skunks, sea gulls and wild cats hunt for juvenile pelicans. Humans are also predators of the pelican, hunting them for their feathers and eating the meat.
Pelicans are a large bird, which makes them harder prey for most predators in their natural environment. Because of this, most animals do not hunt them. However, a wounded pelican that cannot fly is easy prey for wild dogs, feral cats and larger mammals.
Along with the hunting of pelicans, humans have also caused the decline in the pelican population with pesticides, such as DDT. These pesticides cause the eggs of pelicans to remain infertile or hatch damaged chicks. Some pelican species are still endangered in North America.
