Heavy showers and thunderclouds passed over at intervals during the whole morning, rendering our shooting not quite so successful as it might have been; still we procured about fifty pigeons and a few of Duperrey's megapodius. In habits this last bird resembles the Australian species, especially in constructing enormous mounds for the reception of its eggs. Those which I saw averaged five feet in height and fifteen in diameter, and were composed of the sandy soil of the neighbourhood, mixed up with rotten sticks and leaves, but without any shells or coral. Some were placed on the outer margin of the thickets close to the beach, and others were scattered about more inland. As several of these mounds showed indications of having lately been opened by the birds, I entertained hopes of being able to procure an egg, but after digging several pits three feet in depth, with no more efficient implements than my hands, I had to give up the work from sheer exhaustion. This bird is apparently very pugnacious at times, as I frequently saw them chasing each other along the ground, running with great swiftness, and uttering their cry more loudly than usual, stopping short suddenly and again starting off in pursuit. The cry consists of one or two shrill notes, uttered at intervals and ending in a hurried tremulous cry repeated five or six times. The noise made by this megapodius while scratching among the dead leaves for food may sometimes be imitated with such success as to bring the bird running up within gunshot. When suddenly forced to rise from the ground it flies up into a tree, and remains there motionless, but exceedingly vigilant, ready to start on the approach of anyone, but on other occasions it trusts to its legs to escape. Its food is entirely procured on the ground, and consists of insects and their larvae (especially the pupae of ants) small snails, and various fallen seeds and fruits. Although a great number of the Nicobar pigeons had left, many yet remained, and the whole island resounded with their cry mixed up with the cooing of the Nutmeg pigeon. Little skill is required in shooting these birds, for they generally admit of very close approach, as if trusting to the chance of being overlooked among the dense foliage. ARE VISITED BY NATIVES.
