Great-billed Parrot
Tanygnathus megalorynchos
A large green parrot with a massive red bill and prominent yellow markings on the wings. In flight, shows yellow underwings. Found singly or in pairs or small groups within forest, mangroves, and plantations in lowlands and foothills. Distinguished from Blue-backed and Black-lored Parrots by yellow wing markings. Differs from Blue-naped Parrot in yellow underwings and lack of blue on head, and differs from male Eclectus Parrot in lack of red flank patch. Noisy, with varied calls that include harsh shrieks “KEEK-KEEK-KEEK…”, an ear-splitting, grating “ER,” and a high-pitched, rising whistle “keeYIP.”
识别特征
The great-billed parrot (Tanygnathus megalorynchos) also known as Moluccan parrot or island parrot, is a medium-sized, approximately 38 cm long, green parrot with a massive red bill, cream iris, blackish shoulders, olive green back, pale blue rump and yellowish green underparts. The female is typically smaller than the male, but otherwise the sexes are similar. The great-billed parrot is found in forest, woodland and mangrove in the south-east Asian islands of Maluku, Raja Ampat, Talaud, Sangir, Sarangani, the Lesser Sundas, and nearby small islands. The diet consists mainly of fruits. It remains widespread and locally fairly common, and consequently has been rated as least concern on the IUCN Red List of Threatened Species.
分类信息
The great-billed parrot was described by the French polymath Georges-Louis Leclerc, Comte de Buffon in 1780 in his Histoire Naturelle des Oiseaux from a specimen collected in New Guinea. The bird was also illustrated in a hand-coloured plate engraved by François-Nicolas Martinet in the Planches Enluminées D'Histoire Naturelle which was produced under the supervision of Edme-Louis Daubenton to accompany Buffon's text. Neither the plate caption nor Buffon's description included a scientific name but in 1783 the Dutch naturalist Pieter Boddaert coined the binomial name Psittacus megalorynchos in his catalogue of the Planches Enluminées. The great-billed parrot is now placed in the genus Tanygnathus that was introduced by the German naturalist Johann Wagler in 1832. The generic name combines the Ancient Greek words tanuō "to stretch out" and gnathos "jaw". The specific epithet megalorynchos combines the Ancient Greek megalos "great" and rhunkhos "bill". <p>Five subspecies are recognized:

Lesser Crested Tern
Thalasseus bengalensis
Elegant medium-sized tern with a slender yellow-orange bill and black crown. Can be confused with Great Crested Tern; note proportionally longer, more orangey bill on Lesser Crested. Also note gray upperwing, which separates it from Sandwich Tern. Gray rump and tail are diagnostic if seen well. On juveniles, note dull legs, secondaries with dark centers, and a weakly patterned upperwing. Strictly coastal, usually found on beaches and estuaries. Call a noisy “kerrrick.”
White-bellied Fantail
Rhipidura euryura
As the name indicates, a dark gray fantail with a white belly. Also note white eyebrow and white-tipped tail feathers. Malaysian Pied Fantail is somewhat similar, but has a bright white throat, is darker overall, and favors different habitats. Inhabits foothill and montane forests, where it is generally uncommon. Forages actively, often associating with mixed flocks, moving through the lower and middle levels of forest. Often in dense, tangled vegetation. Song is a jumble of high whistled notes. Calls include a quiet “ch’reer” and pips.
Red-billed Starling
Spodiopsar sericeus
Large and social starling of fields, parks, and farmland. Adult’s contrastingly and sharply demarcated white head in both sexes is unique amongst the region's starlings. Females are duller than males, but both have gray bodies and dark wings with a white patch. Juveniles are brown overall with a pale face. Gathers in immense roosts in the winter, often with White-cheeked Starlings. Noisy, often giving harsh and ear-splitting calls, particularly when flying in to roost.
