Horned Parakeet
Eunymphicus cornutus
Spectacular, relatively large mostly green parakeet with blue on the tail and wings, black face, red crown, and thin but prominent “horns” consisting of a crest made up of a pair of black feathers. Found in remnant patches of high-quality forest. Larger than other parrot species on New Caledonia, with a distinctive voice: relatively low-pitched, nasal notes that sound more like some calls of New Caledonian Friarbird than a parakeet.
识别特征
Adult birds usually measure approximately 32 cm (or about 14 inches) in length, including the tail. Like many parrots, the horned parakeet is primarily green in color. This parrot has a yellowish nape with a black and red face and bluish wings and tail. Its most striking feature is a two-feather black crest, with the crest feathers tipped in red.<p>It makes a nasal "kho-khoot" contact call, and also makes a wide range of shrieks and chuckles.
分类信息
The horned parakeet was formally described in 1788 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with all the other parrots in the genus Psittacus and coined the binomial name Psittacus cornutus. Gmelin based his description on the "horned parrot" that had been described and illustrated in 1781 by the English ornithologist John Latham in his A General Synopsis of Birds. Latham's specimen had been obtained from New Caledonia during Captain James Cook's first voyage to the south Pacific Ocean. The specimen formed part of the collection of Joseph Banks. The horned parakeet is now placed with the Ouvea parakeet in the genus Eunymphicus that was introduced in 1937 by the American ornithologist James L. Peters. The genus name combines the Ancient Greek eu meaning "true" and the genus name Nymphicus that had been introduce in 1832 by Johann Georg Wagler for the cockatiel. The specific epithet cornutus is Latin meaning "horned".<p>In 1998, it was found through DNA studies that Eunymphicus cornutus, the horned parakeet, and Eunymphicus uvaeensis, the Ouvea parakeet, were two separate species.

Burchell's Starling
Lamprotornis australis
A large, long-tailed, iridescent blue-green to purple glossy starling with barred wings, and a round-tipped tail. Pairs, groups, and small flocks are resident in dry savanna, especially near thorn trees, where they have become common in camps and often associate with humans. The species feeds on the ground, walking with long strides and sitting low in trees, searching for insects, small vertebrates, and plant matter to eat. The similar Meves’s Starling differs from Burchell’s Starling by being bluer and smaller, with a more strongly graduated tail that is proportionately longer.
Spectacled Parrotbill
Suthora conspicillata
A plain and relatively unmarked brown parrotbill with a pale bill and bright white eyering. Found in foothill and montane forests, where small flocks are usually encountered roaming about in dense stands of bamboo. Occasionally visits reedy and grassy areas in intermontane valleys. Gives low chattery trills and high, plaintive whistles. Generally uncommon.
Red-crowned Woodpecker
Melanerpes rubricapillus
Medium-sized woodpecker found from Costa Rica to northern South America. Pale buffy overall with a red nape and belly and black-and-white barring on the back. Female has a pale crown with restricted red on the back of the nape; male has red extending to top of crown. Common in open woodlands, second growth, and gardens. Distinctive in range, but hybridizes extensively with Hoffmann’s Woodpecker on the Pacific slope in Costa Rica. Hybrids usually show orange nape and belly.
