Pelican on a pile.

Amongst the heaviest flying birds in the world, pelicans as a group evolved from marine ancestors, but six of the seven species including the Australian pelican spend most of their time on rivers, lakes, inland seas and coastal waters. Male Australian pelicans can weigh in excess of 10 kg, but 8 kg is a more usual upper weight. Recognised instantly by their massive bill and pouch, pelicans mainly eat fish, and they nest colonially. They soar spectacularly on thermals, occasionally to great heights (3000 m or more), and they display precise orchestration of movement when feeding cooperatively or flying in V formation.
