Columbidae : The bird family that includes pigeons and doves, with stout bodies, short bills, and crop-produced milk. The Nicobar pigeon belongs to this family, whose shared traits distinguish it from other birds.
Seed dispersal : The movement of seeds away from parent plants by wind, water, or animals. By eating fruits and moving among islands, it can transport seeds.
Dodo : An extinct flightless bird from Mauritius, known from historical accounts and subfossil remains. Both belong to the pigeon family and exemplify its island radiations.
Near threatened : An IUCN Red List category for species close to qualifying for a threatened category. The species is assessed as Near Threatened, reflecting risks that merit monitoring.
Island biogeography : The study of how island area, isolation, and habitat shape species distributions and diversity. Its scattered island range raises questions about dispersal and isolation.
Zoo conservation : The use of managed animal populations and coordinated breeding to support species conservation. Captive populations have been maintained in zoos, where breeding and care are managed.
Crowned pigeon : A large ground-dwelling pigeon native to New Guinea and nearby islands, recognized by its ornate crest. It is another large island pigeon, but lives farther south in New Guinea.
Habitat fragmentation : The division of continuous habitat into smaller, isolated patches, often through human activity. Forest loss and fragmentation can reduce suitable habitat across its island range.
Iridescence : An optical effect in which color changes with viewing angle because of interference or structural reflection. Its metallic-looking feathers owe their shifting colors to structural effects.
Wildlife trade : The legal and illegal commerce in wild animals and their parts. Capture for the live-bird trade is a pressure considered in its conservation.
