January 7th.

Along with a shooting party I landed soon after daylight on the
westernmost Duchateau Island. Numbers of Nicobar pigeons left the island
as we approached, having apparently used it merely as a roosting-place.

HABITS OF DUPERREY'S MEGAPODIUS.

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
