Nicobar Megapode
Megapodius nicobariensis
Large, brownish bird with a small gray head and massive legs and feet. Forages on the ground in coastal forests in the Nicobar Islands. Builds a large mound for a nest, from where the newly-hatched chicks dig themselves out and become immediately independent. Said to sing when it is dark, giving out a series of low-pitched wails which then reach a crescendo, culminating in a loud, metallic clattering sound.
Identification
Megapodes are so named for their large feet and like others in the group, this species is fowl like with dark brown plumage, a short tail and large feet and claws. The tarsus is bare with the hind toe situated on the same level as the front toes unlike those of other Galliform birds, enabling them to grasp objects better than other game birds. The tarsus has broad flat strip like scales on the front. The tail is short with twelve feathers. The head is more grey with a rufous crest and bare reddish facial skin. The males and females are very similar but the male is dark brown overall while the female has more grey on the underparts. Young birds have a fully feathered face and hatchlings are small quail-like with rufous barring on the wings and back. The nominate subspecies is paler than abbotti from the islands south of the Sombrero Channel.
Taxonomy
This species was collected by Reverend Jean Pierre Barbe and described by Edward Blyth in 1846. Some workers have considered the species to be subspecies of the dusky megapode (Megapodius freycinet). The exact island from which the original type specimen came was not known and a later specimen from Trinkat Island, described as Megapodius trinkutensis is now considered to be indistinguishable from the nominate subspecies. In 1901, W L Abbott collected specimens from Little Nicobar which were described in 1919 by H C Oberholser as a new subspecies abbotti, distinguished by its darker brown plumage.

Range and habitat
The species is found only in the Nicobar Islands. This range is so well separated from the main megapode distribution (especially of the genus Megapodius) that in 1911, it was suggested, on the basis that many megapodes were domesticated and transported by native islanders, that it may have been introduced into the Nicobar Islands. There have been suggestions that the species may have formerly occurred in the Andaman Islands as there are some late 19th century reports of the species on Great Coco and Table Island. The nominate subspecies is found on the islands north of the Sombrero Channel while abbotti is found south of it. It has been found on the islands of Tillangchong, Bompuka, Teressa, Camorta, Trinket, Nancowry, Katchal, Meroe, Trak, Treis, Menchal, Little Nicobar, Kondul, Great Nicobar and Megapode Island. The species may have occurred on Car Nicobar in the early 1900s. A survey after the 2004 tsunami, however, indicated that the species had been extirpated on the islands of Trax and Megapode. The eggs as well as adults are sought after by natives for food and birds may have been transported across islands. The 19th century ornithologist Allan Octavian Hume considered the taste of the meat as being between that of a "fat Norfolk turkey and a fat Norfolk pheasant".

Other Birds
Red-billed Quelea
Quelea quelea
A small, short-tailed weaver with a mottled back and a yellow or reddish bill, eye-ring, and legs. When breeding, the male develops a variable black face mask with a surrounding wash that can be rosy, buff, or cinnamon, although the face can also be whitish. Large flocks are resident and nomadic in arid savanna, grassland, and cultivated areas. In wetter years this species forms enormous flocks numbering tens of thousands, earning it the name “feathered locust.” Non-breeding Red-headed Weaver is superficially similar, but it is much larger than Red-billed Quelea, and it is mostly solitary in woodland and has an unstreaked back.
Ruddy Spinetail
Synallaxis rutilans
Small, patchily distributed bird humid forests. Entirely rufous in most of its expansive range, but at the eastern end of its distribution in Brazil it is mostly sooty-colored with rufous wings. Long-tailed profile, terrestrial habits, and small black mask should clinch identification. Found near the ground inside lowland forest and in premontane forest in the tepui region, often around treefall gaps or other areas with dense understory. Often in pairs. Vocal; two-noted song often given in duet is distinctive in habitat.
White-chinned Thrush
Turdus aurantius
A dark plumaged ground feeder that prefers wooded areas but also occurs in gardens and plantations. Its most distinctive features are its bright orange bill and legs. The namesake white chin is inconspicuous. Also note the white slash, which is usually visible, on the upper wing. Superficially similar to the shier White-eyed Thrush, which has a white eye plus a dark bill and legs. Most common call is a slightly shrill, up-slurred “p’weet,” sometimes given as a longer “p’ooo-weeet.” Song is a series of varied sweet notes given singly or as couplets.
