Megapodes are also known as mound builders and incubator birds. These birds have large feet which they use to make big heaps of vegetation or shallow burrows in which they incubate their eggs. Unusually, their chicks are quite well-developed and have their feathers by the time they hatch so they don't need parental care (precocial).
Scientific name: Megapodiidae
An unusual strategy makes good use of volcanic heat.
'When I fumbled the egg and dropped it I really thought the whole day's filming was about to be wasted. It would have been a real shame for the megapode bird as well - who'd just spent all that time digging a hole and laying the egg!' (George McGavin)
