Although not being considered dangerous, pelicans are quite big and you wouldn´t want to mess with them!

The diet of pelicans usually consists of fish, but occasionally amphibians, turtles, crustaceans, insects, birds, and mammals are also eaten. The size of the preferred prey fish varies depending on pelican species and location. Apparently pelicans have even been observed eating smaller birds, sometimes scooping up water in order to drown them before swallowing.
