Antipodes Parakeet
Cyanoramphus unicolor
Entirely green parakeet endemic to the subantarctic Antipodes Islands. The largest of New Zealand’s native parakeets. Males are larger than females. Common throughout their habitat and range, walking and climbing through vegetation when foraging. Will scavenge bird carcasses. An inquisitive bird, often approaching human visitors. Call is a distinctive deep “kok-kok-kok-kok” chatter. Shares its range with Reischek’s parakeet, but distinguishable by much larger size and lack of a red crown.
识别特征

分类信息
The Antipodes parakeet was depicted in 1831 by the English artist Edward Lear in his Illustrations of the Family of Psittacidae, or Parrots. Lear used the common name "Uniform parakeet" and coined the binomial name Platycercus unicolor. The species is now placed in the genus Cyanoramphus that was introduced in 1854 by the French ornithologist Charles Lucien Bonaparte.<p>Its closest relative is Reischek's parakeet, which also lives on the Antipodes Islands. Other relatives include the Norfolk parakeet, Society parakeet and Chatham parakeet.

分布与栖息地
The Antipodes parakeet is endemic to the Antipodes Islands of New Zealand. They are common on the main Antipodes Island, but are less common on smaller islands in the group such as Bollons Island. They live in very small numbers on Leeward Island, where they only live in a 0.1 square kilometre region of the island. The Antipodes parakeet also live on the 0.1 square kilometre Archway Island as well.

行为
These parakeets eat leaves, buds, grass, and tussock stalks, as well as sometimes feeding on seeds and flowers, and will scavenge dead seabirds. The Antipodes parakeet also preys on grey-backed storm petrels, entering burrows to kill incubating adults, even digging at the entrance if it is too small.<p>Antipodes parakeets spend much of their time on the ground and in very small groups, in pairs or solitary.<p>They are quite inquisitive, territorial, probing and mischievous.<p>Their nest is in a tunnel 2 metres beneath the fibrous peat away from the wind.

Knob-billed Duck
Sarkidiornis melanotos
Large bicolored waterbird. Both sexes are iridescent purplish-green above with a white or buffy breast. Males have a large black lump on the bill, gray flanks and whitish belly, whereas females have a plain bill and gray flanks. Note all dark wings. Occurs throughout much of Africa, India, and Southeast Asia. Found in freshwater rivers, lakes, and marshes where it is usually uncommon. Normally silent.
Variable Hawk
Geranoaetus polyosoma
Common raptor in open spaces in the high Andes and southern South America. Large, relatively broad-winged, and short-tailed raptor. As the name suggests, plumage is quite variable. Adults range from clean white to dark gray and rufous below with a gray or rufous back. Always look for the white tail with a black band near the tip. Juveniles are more confusing, usually dark brown above and buffy below with a variable amount of dark streaking below. Juveniles can also be all dark brown (but this morph is rare). Compare with Black-chested Buzzard-Eagle, which is larger and broader-winged, with young birds usually darker than most Variable Hawks. Occurs from sea level up to over 4,500 m in the Andes, typically in open agricultural land, desert, or paramo, but also ranging over wooded areas.
White-necked Jacobin
Florisuga mellivora
Rather large, spectacular hummingbird of humid tropical lowlands that favors forest edges, adjacent clearings with scattered trees and flowering bushes, and gardens. Feeds at all levels, often in the canopy, hovering with its tail cocked and occasionally opening it to show extensive white. Male has deep blue hood, green upperparts with white collar (often hard to see), white underparts, and mostly white tail. Some females look similar to males while others look very different, with dark spotting below and a mostly green tail with white tips.
