Bar-tailed cuckoo-dove

The bar-tailed cuckoo-dove or black-billed cuckoo-dove is a species of bird in the family Columbidae. It is native to New Guinea and the Bismarck Archipelago. It is rated as a species of least concern on the International Union for Conservation of Nature Red List of Endangered Species.

Description

The bar-tailed cuckoo-dove measures in length. It has a short, completely black bill. The six central tail feathers are black barred. The central breast feathers are not bifurcated. The male is ruddy-brown, with no clear distinction between the underparts and the upperparts. The female, however, has black barred upperparts. The juvenile is similar to the female, but its tail is barred irregularly.
It is differentiated from other sympatric pigeons other than cuckoo-doves, by its chestnut brown plumage and slender, long tail.

Distribution and habitat

It is native to Papua New Guinea and Indonesia. It inhabits old-growth forests, forest peripheries, and second-growth forests. It also occurs commonly on submontane forests on altitudes of up to from sea levels, and occasionally at sea levels on hills adjacent to coasts.

Status and conservation

Since 1988, the bar-tailed cuckoo-dove has been rated as a species of least concern on the IUCN Red List of Endangered Species. This is because it has a very large range—more than 20,000 km² —and because it has a stable population trend. Also, although its population numbers has not been determined, it is commonly found throughout most of its distribution, it is thought to be above 10,000 which is above the criterion to warrant it a vulnerable rating. There are no substantial threats thought to be to this species.
