Pukekos live near bodies of water like swamps, streams, ponds, and ditches where they can get their feet wet and find shelter and grass. They lay buff colored eggs with brown blotches in nests of 4-6 eggs that hatch within 23-27 days. Pukekos eat various plants, roots, seeds, crops, insects, worms, small fish and frogs, duck eggs, and young birds. They can fly long distances by running first and flapping their wings, landing on soft grass and slowing down before landing while screeching loudly. Males impress females through bill nibbling before mating by jumping on each other's backs and feeding females food to feed to babies.
