分类信息
The rose-crowned fruit dove was formally described in 1825 by the English naturalist William Swainson. He considered his specimens as a variant of the grey-green fruit dove (Ptilinopus purpuratus) and specified the scientific name as Ptilinopus purpuratus var. Regina. The type locality is New South Wales.<p>Five subspecies are recognised:

Middle Spotted Woodpecker
Dendrocoptes medius
Medium-large black-and-white woodpecker. Marginally smaller than Great Spotted Woodpecker, but rounded head and shortish beak exaggerate this size difference. Both sexes are similar, with a red crown (brighter in the male) and an incomplete cheek bar. It has a rattle call: "kíg-gag-gag-gag-gag" and gives a nasal long-drawn series of “gwaaag” calls. Rarely drums. Closely tied to old deciduous forests, often in areas with an abundance of oak or beech.
Pale-bellied Tapaculo
Scytalopus griseicollis
Small and plain gray like most other Scytalopus tapaculos, but look for slightly paler belly and fairly bright tawny flanks without barring. Restricted to the eastern Andes of Colombia, from just south of Bogotá to the Venezuelan border. Acts like a mouse, scurrying around on or near the ground within montane forest and scrubby areas from around 2,000 to 3,300 m. Listen for fast, froglike trill.
Collared Nightjar
Gactornis enarratus
Beautifully patterned cryptic nightjar. Found mainly inside of eastern and northern Madagascar rainforest, though very locally in dry forest. Most often seen when located by local guides, sleeping on the forest floor during the day, usually below a pandanus. Apparently completely silent, which is bizarre for a member of the nightjar family. When perched, distinguished from Madagascar Nightjar by its rufous collar; in flight, by its lack of white in the wings.
