Dusky megapode Dusky megapode The dusky megapode or dusky scrubfowl ("Megapodius freycinet") is a medium-sized (about 41 cm long), blackish bird with a short pointed crest, bare red facial skin, dark legs, brown irises, and dark brown and yellow bill. The male and female are similar. This terrestrial species lives in forests and swamps, including mangroves, of the Maluku and Raja Ampat Islands in Indonesia. Like other megapodes, it lays its eggs in a mound made from earth mixed with leaves, sand, gravel, and sticks, as big as in diameter and stand nearly tall. Many authorities include the Biak scrubfowl as a
Megapode was thought to exhibit temperature-dependent sex determination, this was later proven false; temperature does, however, affect embryo mortality and resulting offspring sex ratios. The nonsocial nature of their incubation raises questions as to how the hatchlings come to recognise other members of their species, which is due to imprinting in other members of the order Galliformes. Research suggests an instinctive visual recognition of specific movement patterns is made by the individual species of megapode. Megapode chicks do not have an egg tooth; they use their powerful claws to break out of the egg, and then tunnel their way up to
