Pelicans are gregarious birds, travelling in flocks, hunting cooperatively, and breeding colonially. They are thought to have evolved in the Old World and spread into the Americas. Their populations have fallen through habitat destruction, disturbance, and environmental pollution, and three species are of conservation concern.
Preening is a maintenance behavior found in birds that involves the use of the beak to position feathers, interlock feather barbules that have become separated, clean plumage, and keep
ectoparasites in check colonially.
