Found throughout Australia, Papua New Guinea and western Indonesia, with occasional reports in New Zealand and various western Pacific islands. In Australia it is widespread on freshwater, estuarine and marine wetlands and waterways including lakes, swamps, rivers, coastal islands and shores. Pelicans mainly eat fish, but they are opportunistic feeders and eat a variety of aquatic animals including crustaceans, tadpoles and turtles. Pelicans are usually very social birds and colonial breeders with up to 40 000 individuals grouping on islands or secluded shores. Breeding may occur at any time of year depending on environmental conditions, particularly rainfall.
