Red-cheeked Parrot
Geoffroyus geoffroyi
Compact, bulky medium-sized green parrot of wet forests in Cape York and lowlands of New Guinea. Male has rose-pink face, violet crown, reddish upper mandible, and pale eye. Female has brown head, pale eye, and dusky bill; juvenile greenish overall with dark eye and orange bill that turns gray. In flight, bright pale blue underwings contrast with green belly and pink face in male. Much larger than tiny Double-eyed Fig-Parrot. Calls include high-pitched squeaks (similar to Australian King-Parrot) and repeated incisive squeaks.
识别特征
Both the male and female red-cheeked parrot have predominantly bright green plumage and a stocky body with a short tail. The adult male has pink-tinged red cheeks and face with a blue-mauve back of head and crown, chestnut wing coverts, blue under wing, and a coral-pink upper mandible. The female has a brown head and more olive-brown cheeks and throat, and all brown-grey bill. Juveniles also have the olive tinge, but their heads are more green. All red-cheeked parrots have yellow eyes. Their beaks are designed for eating seeds and fruit. Their swift and direct flight pattern is distinct and similar to that of a starling. Their call is "metallic". Typical body dimensions are: height 250 mm (9.8 in), length 203 mm (8.0 in), and wing span 135 to 155 mm (5.3–6.1 in).
分类信息
The red-cheeked parrot was first described by the German naturalist Johann Matthäus Bechstein, 1811. It is one of three species classified in the genus Geoffroyus. This genus has occasionally been merged into Psittinus. Proposed races sumbavensis and tjindanae are synonyms of floresianus; stresemanni of rhodops; explorator too may be synonymous with rhodops.<p>Seventeen subspecies of the red-cheeked parrot are now recognized.

分布与栖息地
The red-cheeked parrot is found in Cape York Peninsula, Australia, Indonesia, East Timor, and Papua New Guinea and several other islands in the region. Its natural habitats are subtropical or tropical dry forests, subtropical or tropical moist lowland forests, and subtropical or tropical mangrove forests. They live along streams and in forests.

行为
Red-cheeked parrots usually live in pairs, and small family groups outside of the breeding season. During the breeding season the birds are usually found in pairs but there is little else known of their courtship behavior in the wild. They are usually quite shy, except while feeding. When feeding they gather in large groups, and they are very noisy and conspicuous. They only walk short distances as their feet are not structured for walking, but for perching. They forage for food and their diet consists of seeds, fruits (mainly figs), blossoms, and nectar. Fruit and seeds of Corymbia papuana, Casuarina papuana and scaly ash (Ganophyllum falcatum) are among those recorded as diet items. During the breeding season the female bird excavates its nest in a rotting tree limb. A clutch usually contains three eggs.
保护状况
The species has a large range. There is an unknown number of individuals, but their numbers are thought to be stable. Their conservation status is classified as Least Concern by the IUCN.

Willet
Tringa semipalmata
Large, stocky shorebird with a distinctive black-and-white wing pattern. Larger than Greater Yellowlegs, smaller than godwits. Overall grayish, with messy dark patterning in breeding plumage. Bill is straight and rather thick, with a paler base. Legs are grayish. Two distinct subspecies. “Eastern” Willet is smaller, darker, browner, shorter-billed, shorter-legged, and strictly coastal. Breeds in saltmarshes from Atlantic Canada to the Gulf of Mexico; migrates early, mostly departing the U.S. in August, and winters almost exclusively on the northern coast of South America. Especially likely to be seen foraging on extensive mudflats, sometimes in flocks. “Western” Willet is larger, paler, grayer, longer-billed, and longer-legged, giving it a more godwitlike appearance. Breeds in marshy grasslands in the Interior West; winters much further north than “Eastern” Willet, from both coasts of the U.S. to as far south as Chile. Especially likely to be seen on beaches.
Mosque Swallow
Cecropis senegalensis
This large swallow has rusty-red underparts, a pale buff throat, and a white leading edge to the underwing that is obvious only in flight. It is mostly resident, although it is also a wet season migrant to the north of its range. Pairs prefer wooded savanna, nesting in banks, termite mounds, and often holes in trees, particularly baobabs. The Mosque Swallow may be confused with the juvenile Rufous-chested Swallow, but it lacks the latter species’ dark “ear-flaps” and buffy forward part of the underwing.
Olive-crowned Crescentchest
Melanopareia maximiliani
Spectacular but reclusive bird, most often located by its distinctive voice. In N end of range (to NW Bolivia) lives in thick grassy hillsides and Polylepis forest in the high Andes. S of Bolivia, in W Paraguay to central Argentina, expands into Chaco forest in lowlands, where it prefers thorn forest with dense understory. Song an evenly pitched series of metallic or dry notes. Population in central Argentina differs vocally, with a much faster song.
