Madagascar Green-Pigeon

Treron australis

Medium-sized chunky pigeon that is mostly pale green, with black wings and a pale wing stripe. Flight is very fast and direct. Sometimes found alone, though more often in small groups. Widespread but erratic; local abundance linked to the availability of fruit, its main food. Found in many habitats including spiny forest, dry deciduous forest, rainforest, villages, and scrub, mostly at low and middle elevations. Most common in dry habitats in western Madagascar. Voice is a quiet but maniacal series of sputters, whistles, and cackles. This is the only green pigeon within its range.

The Madagascar green pigeon or Madagascan green pigeon (Treron australis) is a species of bird in the family Columbidae. It is endemic to Madagascar. The taxon griveaudi, by most authorities considered a subspecies of the Madagascan green pigeon, is sometimes considered a separate species, the Comoros green pigeon (Treron comorensis). Its natural habitats are subtropical or tropical dry forest and subtropical or tropical moist lowland forest.

分类信息

In 1760 the French zoologist Mathurin Jacques Brisson included a description of the Madagascar green pigeon in his Ornithologie based on specimen that he had examined. He used the French name Le pigeon ramier verd de Madagascar and the Latin Palumbus viridis madagascariensis. The species was also illustrated in Edme-Louis Daubenton's Planches Enluminées D'Histoire Naturelle. Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature. When the Swedish naturalist Carl Linnaeus revised his Mantissa Plantarum in 1771 he added an appendix which included a description of the Madagascar green pigeon. He coined the binomial name Columba australis and cited the earlier authors. The specific epithet australis is the Latin word for "southern". The species is now placed in the genus Treron that was introduced in 1816 by the French ornithologist Louis Pierre Vieillot.<p>Two subspecies are recognised:

Short-billed Leaftosser

Short-billed Leaftosser

Sclerurus rufigularis

Small, brown bird of rainforest floor. Plumage overall dark chestnut brown with a paler throat and blackish tail; bill is thin and slightly decurved. A seldom-seen resident of tall humid forest, where it forages in leaf litter around old fallen logs, tree buttresses, and upturned root masses. Always on or near the ground, flicking leaves in search of insect prey. Usually encountered alone and does not follow mixed-species flocks. Most readily detected when flushed or disturbed, and may assess an observer from a low perch, giving a sharp squeaking call note and moving about nervously. Song, given infrequently, is a series of clear, descending, whistled notes with an impatient quality, sometimes ending in a hard rattle. Very similar to South American Leaftosser; Short-billed has shorter bill and is more uniformly brown on breast and belly, but a good view may be required to verify these marks.

Gray-headed Lapwing

Gray-headed Lapwing

Vanellus cinereus

Brown lapwing with a gray head and neck, bright yellow bill, and a white belly and gray breast separated by a dark breast band. When in flight, note striking black primary feathers and white secondaries, as well as a white rump and dark tail. Gregarious, usually seen in loose small flocks, sometimes with other lapwings. Inhabits cultivated wetlands and marshy areas, feeding mainly on insects, worms, and crustaceans. Gives grating, piping screams.

Black-and-tawny Seedeater

Black-and-tawny Seedeater

Sporophila nigrorufa

Small seedeater with a short thick bill. Males are black and cinnamon-colored; note the cinnamon rump. Females are green-olive, like other female seedeaters. Occurs in grassy areas near water; may gather in large flocks of up to 100 individuals in the non-breading season, but has a very limited global range.
