It was about 25% larger than its closest living relative, the Nicobar Pigeon.

The Nicobar Pigeon is their closest living genetic relative.

Hence, the Nicobar Pigeon may well constitute another now-monotypic subfamily.

The only living species is the Nicobar Pigeon (C. nicobarica).

Notable animal species found in the park include the giant robber crab, megapode and Nicobar pigeon.

Notwithstanding the Liverpool Pigeon was very different to the Nicobar Pigeon.

These include the Nicobar pigeon, the Andaman pig (the staple diet of some tribal groups) and the crab-eating macaque.

Above the water are found many diverse species such as the Nicobar Pigeon, Mangrove Monitor Lizards and more.

Nicobar Pigeon (Caloenas nicobarica)

The exhibit is also home to magpies, cape-barren geese, ruddy shelducks, imperial and Nicobar pigeons that fly freely around the tall aviary.

The aviary is a large, one-room free flight exhibit that primarily features warm weather birds such as the scarlet ibis, roseate spoonbill and Nicobar pigeon.

Here, more than 30 species of birds are free-flying, including Nicobar pigeons, various species of starlings and ground birds such as crested partridges.

The Liverpool Pigeon, another extinct species from an unknown locality, has only a slightly similarity to the Nicobar Pigeon due to its neck feathers.

The Surin Islands have a broad selection of animal life - including the Nicobar Pigeon and Mangrove Monitor Lizards.

The following cladogram, from Shapiro and colleagues (2002), shows the Nicobar Pigeon's closest relationships within Columbidae, a clade consisting of generally ground-dwelling island endemics.

The primitive molecular clock used to infer the date the ancestors of the Nicobar Pigeon and the didines diverged has since turned out to be both unreliable and miscalibrated.

The park reserve's flora includes tropical evergreen forest, tree fern, and orchids and fauna includes Crab-eating macaque, giant robber crab, megapode, and Nicobar pigeon.

Their closest living relatives are the Nicobar pigeons of Southeast Asia, the crowned pigeons of New Guinea and the toothbilled pigeons of Samoa.

Also, increased travel introduces predators to more and more of the breeding sites, and colonies of the Nicobar Pigeon may be driven to desert such locations or be destroyed outright.

Apart from the didines, this includes such animals as the Goura crowned pigeons, the Pheasant Pigeon, Ducula and Ptilinopus, and the Nicobar Pigeon.

The affinities of the new genus are uncertain, but comparisons with other taxa suggest that, among living species, it is most closely related to the Nicobar Pigeon or the Tooth-billed Pigeon.

Comparison of mitochondrial cytochrome b and 12S rRNA sequences suggests the Nicobar Pigeon (Caloenas nicobarica) is the closest living relative of the Dodo and the Rodrigues Solitaire.

The Nicobar Pigeon (Caloenas nicobarica) is a pigeon found on small islands and in coastal regions from the Nicobar Islands, east through the Malay Archipelago, to the Solomons and Palau.

The Nicobar Pigeon roams in flocks from island to island, usually sleeping on offshore islets where no predators occur and spends the day in areas with better food availability, not shying away from areas inhabited by humans.
