Slaty Cuckoo-Dove
Turacoena modesta
A long-tailed, uniformly slate-gray dove with bare yellow facial skin. Juvenile browner, with white feather edging. Found singly or pairs in forests, forest edges, and nearby wooded areas within the lowlands and foothills. Song starts with several slow, well spaced “wooyup” notes before quickly moving into a rapidly accelerating series of “woop-woop-woop” notes, trailing off at the end.
识别特征
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.
分类信息
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.

分布与栖息地
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.

Brown Babbler
Turdoides plebejus
A dull brownish babbler with brightly colored eyes. Found in moist woodland, dense savanna, scrub, gallery forest, forest edge, cultivated areas, and gardens, almost always in groups that forage actively on the ground. Similar in shape, size, and overall brown coloration to Arrow-marked Babbler, but there is only minor overlap in range, and Brown Babbler can be separated by the paler face and throat and the less pointed white markings on the underparts. Calls include a raspy babbling and a dry clucking, both usually by a whole group in chorus.
Pennant-winged Nightjar
Caprimulgus vexillarius
Breeding males have extraordinary “pennants” growing out of their wings. Non-breeding males are still distinctive due to the huge white patches on the wings. Females are very drab, and lack white in the wing or tail, unlike most nightjars. This is a migratory species that is found in many different habitats on migration and during the non-breeding season. Breeds in moist savanna and broadleaved woodland, especially miombo. Song is a slow, squeaky trill. Female is similar to Standard-winged Nightjar, but is larger and has more barring in the wings.
Spice Imperial-Pigeon
Ducula myristicivora
A large, stocky pigeon that is found on islands off the shore of Halmahera and far western Papua. Gray head, emerald-green back and wings, blue tail and rusty vent. The eye is red and there is a large knob-like projection on the front top of the bill. Found in a variety of forested habitats, and some wander between islands, sometimes straying to the mainland. Voice a deep, gravelly, 2-note “grrr-waw”, with the second note higher than the first. Similar Spectacled Imperial-Pigeon may co-occur but is separated by its white spectacle around the eye and lack of a knob on the bill.
