Slaty Cuckoo-Dove

Identificazione

The black cuckoo-dove is a medium-sized cuckoo-dove with a length of 38.5–42 cm (15.2–16.5 in). Both sexes are similar in appearance. It is mainly dark bluish-gray, with the color being lighter on the head and underparts and almost black on the wings and tail. The feathers on the top of the head, nape, neck, breast and upper back have iridescent green or purple fringes. The orbital skin is yellow, while the iris has a yellow inner ring and a red outer ring. The legs and beak are black. Juveniles are duller, with brownish-grey plumage, and have light fawn-white fringes to feathers.<p>The advertising call is a long crrruah...crrruah..rrah.rah.ra.ra.ra-ra-ra-r-r-r-r which starts with purrs that are similar to those of the European turtle dove and then becomes a series of stuttering notes before fading. It lasts for 6–8 seconds and consists of 20–25 notes. It is repeated around every half minute.

Tassonomia

The black cuckoo-dove was first described as Columba modesta by the Dutch zoologist Coenraad Temminck in 1835 based on a specimen from Timor. It was then moved to the genus Macropygia by the English zoologist George Robert Gray in 1844, before finally being moved to Turacoena in 1856. The name of the genus, Turacoena, is after the genus Turacus (now treated as a synonym of Tauraco) and the Ancient Greek word oinas, meaning pigeon. The specific name modesta is from the Latin word modestus, meaning plain or modest. Black cuckoo-dove is the official common name designated by the International Ornithologists' Union. Other common names for the species include black dove, Timor cuckoo-dove, Timor black cuckoo-dove, Timor black pigeon, and slate-colored cuckoo-dove.<p>The black cuckoo-dove is one of three species in the genus Turacoena and is most closely related to the white-faced cuckoo dove. It does not have any subspecies.

Areale e habitat

The black cuckoo-dove is endemic to the Lesser Sunda Islands and is found on Timor, Wetar, Rote, and Atauro. It inhabits primary and secondary monsoon forest, eucalyptus forest, and woodland at elevations of up to 1,770 m (5,810 ft) and is moderately tolerant of habitat destruction. It is thought to migrate seasonally depending on food availability.
