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.”
Identification
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.
Taxonomy
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:

Turquoise-fronted Amazon
Amazona aestiva
Large, frequently encountered parrot of woodlands, savannas, and open areas. The body is bright green with a blue forehead and a yellow crown.

Black-fronted Tern
Chlidonias albostriatus
A medium to small blue-gray tern endemic to New Zealand. Breeding birds have a black cap extending down to the bill and bright orange bill and legs. Non-breeding plumage dulls to a mottled gray cap and black patch around the eye, also seen in juveniles. Breeds only along the braided rivers of the eastern South Island. Will defend nest from intruders by diving, calling harshly, and hitting intruders on the head. After breeding, populations disperse to coastal areas, foraging offshore and near coastal farmland. A small number will visit the North Island. Call is a repetitive “kit.”
