Pile-builder megapode ulna, a distal left ulna, a distal-end left ulna proximal, and a half right femur. When the early settlers of the Lapita culture arrived in Tonga around 1500 BC, they found only marine species such as sea turtles and giant forms of terrestrial birds such as megapodes, doves, and rails. The hunting of these bird species for food led to their rapid extinction. In New Caledonia, the giant megapode might have survived into historic times. William Anderson, a naturalist and surgeon's mate aboard during James Cook's second South Sea voyage, described a bird from New Caledonia with bare legs, which
Nicobar megapode Nicobar megapode The Nicobar megapode or Nicobar scrubfowl ("Megapodius nicobariensis") is a megapode found in some of the Nicobar Islands (India). Like other megapode relatives, it builds a large mound nest with soil and vegetation, with the eggs hatched by the heat produced by decomposition. Newly hatched chicks climb out of the loose soil of the mound and being fully feathered are capable of flight. The Nicobar Islands are on the edge of the distribution of megapodes, well separated from the nearest ranges of other megapode species. Being restricted to small islands and threatened by hunting, the species is vulnerable
