Description

The Micronesian megapode is a stocky medium-sized bird that is mostly dark brownish-black in appearance. Its head is paler than its body, and it has a pale grey crest, a yellow bill, and large dull-yellow legs and feet. It is 38 cm. Medium-sized, dark megapode with paler head. Mostly brownish-black with short pale grey crest. Yellow bill, red facial skin showing through thin feathers. Unusually large, dingy yellow legs and feet. Similar species. Could be confused with dark morphs of Red Junglefowl Gallus gallus (or feral domestic stock). Its call is a loud "keek", song often a duet with one bird beginning a rising and accelerating "keek-keek-keek-keek"- etc. culminating in a loud "kee-keer-kew" (Palau) or "keek-keer-keet" (Marianas), the other answering with a rising cackle that slows near the end. .

Behavior

Often shy and secretive, but becomes relatively tame on inhabited islands where protected from disturbance. Visits nesting mounds several times a day. The birds are known to creep around in the shadows of small trees and are not capable of flying for long distances. However they are accomplished runners and would be very hard to catch. The Micronesian scrubfowl and some other

s are the only birds known to incubate their eggs using volcanic heat.

comes in, the females make large mounds of debris in which to lay their eggs. Some individual females will lay their eggs together in the same mound. However the females do not use the same mound more than once and are swapped with different females. When the eggs hatch after one to two months later, the chicks will feed on grass shoots and insects.

Conservation

The species is currently classified as

endangered An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching, inv ...

Along with increased predation, during the Japanese occupation of the islands of Saipan and Tinian, most of the vegetation of both islands was burnt and replaced by large sugar cane farms. It is estimated that only 2000–2500 of the species remain. It can be found in the island nation of

chain, with several hundred on Sarigan. A relatively small population has remained on

throughout the years. The bird appears on the 2010 IUCN Red List Category (as evaluated by BirdLife International - the official Red List Authority for birds for IUCN). The species qualifies as "Endangered" because it has a very small range, restricted to isolated undisturbed offshore islets, with few birds elsewhere. Given the multiple threats across its range, it is likely to be suffering from a continuing decline. It seems that the only way for the species to be safe is to protect a few small islands and release a small population of megapodes there. That way, a safe population is secured. On the larger and higher islands, an increase of people and introduced pests will sooner or later destroy any megapode populations.
