"This singularly shy bird has acquired its popular name from the
well-remarked habit it has of exclusively frequenting the wild nutmeg tree
(MYRISTICA), in the tops of which it may be said to pass its life, except
during the brief pairing season. Then it commonly selects the denser
scrub or the mangroves, most probably guided by their contiguity to fresh
water. Here it makes its nest, a more than ordinarily careless structure,
the few crossed sticks barely sufficing to prevent the single egg it is
destined to receive, from falling through to the ground. The fruit of the
nutmeg is undoubtedly swallowed whole by the bird, and to the powers of
deglutition is left the separation of the nutritive portion which we
know as mace, from the hard and indigestible nut which is voided in
flight. Thus this elegant little creature becomes the useful means of
disseminating the remarkable nutmeg-tree, and it is found that some
chemical treatment corresponding to that which it undergoes during
sojourn within the body of the bird, is actually necessary before the nut
can be fertilised and induced to take root. So strictly arboreal is this
pigeon in its habits that it is questionable if it ever alights upon the
ground, and so timid that it is impossible to procure specimens unless
stratagem is resorted to."
Some years of repeated observation enable me to offer certain amendments
to this narrative, evidently written by one who has been impressed by
half the life-history of the bird--the half spent on the mainland. The
food of the nutmeg pigeon is multifarious. All sorts of nuts and seeds,
and even fruits are consumed--quandongs, various palm seeds (including
those of the creeping palm or lawyer vine, CALAMUS), nutmeg (MYRISTICA
INSIPIDA, not the nutmeg of commerce, though resembling it), the white
hard seeds of the native cabbage (SCOEVOLA KOENIGII), the Burdekin plum
(PLEIOGYNIUM SOLANDRI), and all sorts of unpromisingly tough and
apparently indigestible, innutritious woodeny nuts and drupes. Moreover,
it fattens on such diet, but still the wonder grows at the happy
provision which enables nuts proportionately of such enormous size to be
swallowed by the bird, and ejected with ease after the pulp or flesh has
been assimilated. As the birds alight on the island after their flight
from the mainland, a portion of the contents of the crop seems to be
expelled. A shower of nuts and seeds comes pattering down through the
leaves to the ground as each company finds resting-place. Perhaps those
only who are suffering from uncomfortable distention so relieve
themselves. The balance of the contents of the crops seem to go through
the ordinary process of digestion. Thus, by the medium of the pigeons,
there is a systematic traffic in and interchange of seeds between the
mainland and the islands. The nutmeg pigeon resorts to islands where
there is no fresh water, and builds a rude platform of twigs, and
occasionally of leaves, on all sorts of trees, in all sorts of
