Moluccan King-Parrot
Alisterus amboinensis
A brightly colored, slender, long-tailed parrot of forest and clearings from the lowlands to mid-mountains in the northwest. Red head and underparts, long bluish tail, blue back, and green or bluish wings depending on the race. Similar to Papuan King-Parrot with little overlap, but Moluccan lacks the pale green shoulder bar of the male and green head of the female. Somewhat similar to Chattering Lory but Moluccan King-Parrot has a blue rather than red back and a longer tail. Gives clear, high-pitched, upslurred piping and harsh scolding calls.
识别特征
An adult Moluccan king parrot measures 35–40 cm (14 in) in length and has a red head and chest, outer wings dull green (except in subspecies A. a. hypophonius, which are blue), mantle, lesser wing coverts and tail-coverts dark purple-blue. Tail darker blackish blue, irises orange, and the legs are dark grey. The lower mandible is blackish, and the upper mandible is orange-red with a blackish tip, except in the subspecies A. a. buruensis, where the entire bill is blackish. Unlike the other species of king parrots, the Moluccan king parrot does not display sexual dimorphism; that is, the sexes have similar plumage. Juvenile birds have a dark-brown bill tipped paler, greenish mantle, dark brown irises and red-tips to lateral tail feathers. Birds reach maturity in one year.
分类信息
In 1760 the French zoologist Mathurin Jacques Brisson included a description of the Moluccan king parrot in his Ornithologie based on a specimen collected on the island of Ambon in Indonesia. He used the French name La perruche rouge d'Amboine and the Latin name Psittaca amboinensis coccinea. 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 in 1766 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the twelfth edition he added 240 species that had been previously described by Brisson. One of these was the Moluccan king parrot. Linnaeus included a terse description, coined the binomial name Psittacus amboinensis and cited Brisson's work. This species is now placed in the genus Alisterus which was introduced by the Australian amateur ornithologist Gregory Mathews in 1911.<p>The Moluccan king parrot is one of three species collectively known as king parrots found in Australia, Papua New Guinea, and Indonesia.<p>There are six subspecies:

行为
Encountered alone or in pairs, occasionally in small groups, it mainly frequents dense cover in the lower and mid-levels of forests. It is inconspicuous and rather quiet, except in flight. It consumes fruit, berries, seeds and buds. Nesting takes place in a tree-hollow. The breeding season begins in February and March, although breeding has not been observed in the wild, in captivity the clutch consists of two eggs which are incubated for 19 days. After hatching the chicks are ready to fledge at nine weeks old.

Chocolate-backed Kingfisher
Halcyon badia
A ventriloquial forest kingfisher that is more often heard than seen as it perches in the subcanopy. Distinctive with its blood red bill, broadly chocolate-brown upperparts, white underparts, and bright blue wing patches and tail. Nests in arboreal termite mounds. Song is a series of ten or more easily imitated whistles that rise and then abruptly fall in pitch, “pew pew pew PEW PEW PEW pew pew.”
Sulphur-bellied Whistler
Pachycephala sulfuriventer
A fairly nondescript thick-billed, sparrow-sized songbird. Upperparts are uniform rich brown and underparts whitish, but particularly note the yellow wash to the lower belly and the base of the undertail. Juvenile has a gray head and rufous-tinged plumage. Restricted to forested foothills and mountains on Sulawesi, where pairs often join mixed-species feeding flocks in the understory and subcanopy. Yellow vent makes this species easily identifiable in its limited range. Song starts with three or four introductory whistles, often on the same pitch, and ends with a powerful upslurred whip note: “wi-wi-wi-WHIYIP.”
Gray Vireo
Vireo vicinior
One of North America's most nondescript birds: pale gray above, lighter whitish below, with a hint of pale spectacles and wingbars. Long-tailed for a vireo, but with a typically thick bill. Occurs on dry rocky slopes with patches of dense brush and trees, especially oaks and junipers. Usually seen singly or in pairs, often detected by voice. Most similar to drab Bell's Vireo but note habitat and size differences. Also compare with Plumbeous Vireo, which is shorter-tailed and more boldly marked.
