Western Hooded Pitta
Pitta sordida
Widespread and beautiful, this jewel of a bird bounces about on the shaded forest floor like a luminous ball, where it can be surprisingly difficult to spot. If seen, note emerald-green body, black head, ruby-red lower belly, and powder-blue wing patch. Birds from the Himalayas east to much of mainland Southeast Asia have a warm brown crown stripe; these birds are migratory, and may turn up in unexpected places, such as city parks. Listen for loud, barking song in a range of wooded habitats, from deep forest to plantations. Formerly grouped together with several other closely related species as “Hooded Pitta.”
分类信息
The western hooded pitta was described by the German zoologist Philipp Statius Müller in 1776 and given the binomial name Turdus sordidus. Statius Müller's description was based on a plate showing the "Merle des Philippines" published by Comte de Buffon in his Planches Enluminées D'Histoire Naturelle. The species is now placed in the genus Pitta that was erected by the French ornithologist Louis Pierre Vieillot in 1816. The specific epithet sordida is Latin for "shabby" or "dirty".<p>Six subspecies are recognised:

行为
Western hooded pittas can reach a length of 16 to 19 cm (6.3 to 7.5 in) and a weight of 42 to 70 g (1.5 to 2.5 oz). It has a black head, chestnut crown and green body and wings. Its diet consists of various insects (including their larvae), which they hunt on the ground, and berries. In the breeding period, which lasts from February to August, they build nests on the ground; both parent take care of the eggs and the fledglings. They are highly territorial and their fluty double-noted whistle calls ("qweeek-qweeek") can be constantly heard from their territories, sometimes throughout the nights.<p>The International Union for Conservation of Nature is concerned in particular about the ongoing loss of habitat that this bird suffers, which is reducing its numbers, but has rated it as being a "least concern species" because the rate of population decline is insufficient to warrant a threatened category.<p>In captivity, western hooded pittas mix well with other species although they may be aggressive toward other pittas when breeding. In London Zoo they are kept in a large walk-through aviary in the restored Blackburn Pavilion bird house, while at the Durrell Wildlife Park they are in a large walk-through exhibit with birds such as Palawan peacock-pheasants and white-rumped shamas.

Buff-banded Rail
Gallirallus philippensis
Small and sneaky rail. Barred belly with a smudged orange-buff chest band. Reddish head with strong pale eyebrow. Makes a loud squeaking call. Usually sticks to dense cover near water, occasionally strutting around the edges or crossing paths. On small islands (e.g. Green Island, Lord Howe Island, Lady Elliot Island) it is extremely tame and abundant.
Belcher's Gull
Larus belcheri
Rather large, dark-backed gull along the Humboldt Current coast. Fairly common to locally common, favoring fishing harbors, beaches, and river mouths; ranges over inshore coastal waters and not found inland. All ages have a broad, clean-cut black tail band and a red-and-black bill tip. Breeding adult has clean white head and lacks the white spots in wingtip seen on the larger and bulkier Kelp Gull. Immature and nonbreeding plumages have a distinctive dark hood and yellowish legs.
Black Swift
Cypseloides niger
Large swift with long, angular, and pointed wings. Entirely black, sometimes with faint pale scaling on belly and forehead. Often fans tail in flight. Seen singly or in small flocks, usually in hilly or mountainous areas. Breeds on cliffs, often behind waterfalls. Slower wingbeats than other swifts. Chattering call notes lower-pitched than other swifts in range.
