Slaty Cuckoo-Dove

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.

Vocalizations. 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.

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.

The black cuckoo-dove is mainly found singly or in pairs in the subcanopy. It is a quiet species and flies swiftly to nearby perches when flushed. It feeds on fruit and forages singly or in pairs in bushes and small trees. Flocks also congregate at fruiting trees. It is parasitized by the quill mite Meitingsunes turacoenas, which is present on its flight feathers.
