The Nicobar Pigeon ( Caloenas nicobarica ), also mane pigeon , Nikobarentaube or Nikobartaube called, is a kind of family of pigeons . The crepuscular collar pigeon is a typical earth pigeon that walks a lot on the ground and only rests in the branches.
The collar pigeon is usually the only representative of its genus. However, the extinct Liverpool pigeon may also belong to the genus Caleonas. DNA analyzes also suggest that the collar dove is closely related to the dodo, which is also extinct .
Appearance
In the male, the head is blackish blue-gray, feathed with a slight silver tinge. It has elongated strands of feathers on the nape of the neck and the iridescent blue, green and bronze colors. The feathers on the back and on the wings are metallic green, while the wing and cover feathers are blue. The beak is blackish gray. The females are slightly smaller and their feather strands are less pronounced. Females also have a smaller nipple than the males.
Distribution, habitat and brood
Collared pigeons are common from the Nicobar Islands to the Philippines and New Guinea . Their breeding colonies on forest-covered atolls and islets sometimes include thousands of breeding pairs. The platform-like nests are built in trees up to twelve meters above the ground. It is not uncommon for there to be several nests in one tree.
The clutch consists of a single egg that is incubated by both parent birds. The incubation period is 30 days. The newly hatched young bird is without down, the skin plum blue. The young bird fledged after 70 to 80 days. The juvenile plumage is initially blackish. It lacks the green gloss that is characteristic of adult birds.
Attitude in Europe
The attractive pigeon was first brought to Europe at the end of the 18th century. In 1872 the zoo in Paris got the first breeding. Breeding success is supported if several breeding pairs are kept together. The collar pigeon can still be seen frequently in free-flight aviaries in zoos. Since the collar pigeon is one of the particularly protected pigeon species, a marketing permit is required for trading in offspring.
