Tórtola-cuco piquinegra

Una paloma de cuerpo pequeño, mayormente parda, con cola larga y pico negro corto y robusto. La cola y la rabadilla fuertemente barreadas son diagnósticas. Se encuentra desde el nivel del mar hasta los 2600 metros de elevación, usualmente sola o en parejas en el borde del bosque, aunque a veces se pueden encontrar grupos de hasta 20 alimentándose en árboles frutales. Muy similar tanto a la Paloma-Cuco Parda de Nueva Guinea como a la Paloma-Cuco de MacKinlay de las Islas Salomón. El macho de Paloma-Cuco Parda se diferencia por ser más grande, con una cabeza grisácea y un parche iridiscente verde en el cuello; la hembra tiene medias lunas negras gruesas bajo la cola. La Paloma-Cuco de MacKinlay es de tamaño similar pero tiene un color canela más claro en el cuerpo que contrasta con las alas castaño más oscuras, mientras que la Paloma-Cuco de Pico Negro es uniformemente pardo rojizo. También se diferencia de ambas especies por su cola superior y rabadilla barreadas. Es comúnmente vocal y más a menudo se le oye emitir una serie rápida de alrededor de doce notas "woi".

Identificación

The bar-tailed cuckoo-dove measures 29 centimetres (11 in) 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.<p>It is differentiated from other sympatric (other species existing in the same geographic area and thus frequently encountering with it) pigeons other than cuckoo-doves, by its chestnut brown plumage and slender, long tail.

Distribución y hábitat

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 2,600 metres (8,500 ft) from sea levels, and occasionally at sea levels on hills adjacent to coasts.

Conservación

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 (7,700 mi2)—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.
