The Nicobar Pigeon (Caloenas nicobarica) is a
pigeon which is a resident breeding bird on small uninhabited islands in
Indonesia and the Nicobar Islands. It is the only member of the genus
Caloenas.



This species nests in dense forest, building a stick nest in a tree and
laying one elliptical, faintly blue-tinged white egg. Its flight is quick,
with the regular beats and an occasional sharp flick of the wings which are
characteristic of pigeons in general.



This is a large, heavy pigeon at 40cm in length. It is mainly metallic green
with green and copper hackles on the neck. The head and upper neck, flight
feathers and breast are dark grey. The tail is very short and pure white.
There is a black knob on the base of the bill, and the strong legs are dark
red. This is not a very vocal species, but the call is a coo-coo-coo.



Females are slightly smaller than males; they have a smaller bill knob,
shorter hackles and browner underparts. Immature birds have a black tail.



The Nicobar Pigeon roams in flocks from island to island, including
inhabited sites, seeking its food of seeds, fruit and some invertebrates,
and is attracted to areas where grain is available.



Comparison of mitochondrial cytochrome b and 12S rRNA sequences (Shapiro et
al., 2002) suggests the Nicobar Pigeon is the closest living relative of the
Dodo and the Rodrigues Solitaire. This does not actually imply a very close
relationship, and at any rate, molecular phylogeny of the Indo-Australian
pigeons has yielded wildly differing results depending on the gene sequence
analyzed.



From subfossil bones found on New Caledonia and Tonga, an extinct species,
the Greater Maned Pigeon (Caloenas canacorum) was described. It was a
sizeable bird, about one-quarter larger than the Nicobar Pigeon. Considering
that it must have been a good source of food, it was most likely hunted to
extinction by the first human settlers of the islands where it occurred.
