Pallid Cuckoo
Heteroscenes pallidus
Large pale cuckoo, which lacks the warmer tones of both Fan-tailed and Brush cuckoos. Yellow eyering, and a dark indistinct stripe across the cheek. Has a distinctive call that has several notes, and tends to perch in prominent places or fence-posts while calling.
识别特征
Characteristics of the appearance of the pallid cuckoo include: a dark bill, a dark eye with a gold eye-ring, a shadowy dark mark from the eye down the neck, a white (or buff) mark on the nape, olive grey feet and prominent white (or buff) toothing along the tail. In flight, there are conspicuous white and dark bars across the long tail. Its silhouette resembles a falcon and often triggers alarm calls from passerines. The pallid cuckoo can have various morphs including light rufous morph or dark rufous morph. <p>In adult males the upperparts including head and neck are grey-brown and have large spots on wing-coverts. In adult females the light-rufous morph is similar to the adult male however with the dark rufous morph the hind neck patch extends onto mantle and it has barring on the chest.<p>A distinguishing feature of the family Cuculidae are the feet, which are zygodactyl, meaning that the two inner toes point forward and the two outer point backward.[citation needed]
分类信息
English ornithologist John Latham described the pallid cuckoo in 1801 as Columba pallida "pale pigeon".<p>Sources differ in the genera placement of this species. It is commonly placed in Cuculus, but genetic evidence and its song support its placement in Cacomantis, with its closest relative the white-crowned cuckoo (Cacomantis leucolophus).<p>"Pallid cuckoo" has been designated the official name by the International Ornithological Committee (IOC). Other common names include unadorned cuckoo, semitone-bird, scale-bird, and brain-fever bird—from its monotonous repetitive call.

分布与栖息地
The pallid cuckoo is widely distributed throughout mainland Australia and Tasmania. It spends the winter months in central inland Australia and the Northern Territory. The cuckoo then migrates to South East Australia's coastal region and Tasmania, arriving generally around September or October, sometimes earlier. It has also been observed that migration occasionally occurs to the islands of Timor and Papua New Guinea in the winter months. It is a rare vagrant to New Zealand.<p>The pallid cuckoo has been observed in various different habitats such as in woodland, shrubland, mangrove forest, pastoral country, farmland, golf courses and gardens. However it prefers lightly timbered country with trees and shrubs and a sparse under-story where it can best hunt for prey.

Gray-green Scrubwren
Aethomyias arfakianus
A small bird of lower montane forest interior. Whitish belly, pale gray head and greenish wing. Pale grayish wash on the chest with faint streaking, offsetting the whitish throat. Actively searches leaves and branches for insects in small groups. Co-occurs at elevations with other scrubwrens including Vogelkop, Pale-billed and Perplexing, but Gray-green has olive rather than warm brown upperparts. Song, a scratchy jumble of notes followed by an up and down “chi-doo! chi-doo! chi-doo!”. Calls, various raspy, nasal notes and chattering.
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.
Gray Junglefowl
Gallus sonneratii
Common relative of the domestic chicken. Endemic to peninsular India where it occurs in deciduous and evergreen forest. Males are grayish with golden markings on the wings, whitish spotting around the neck, a long glossy-black tail, pinkish feet. Red comb and wattle are smaller than the widespread Red Junglefowl. Females are rather plain, lacking the long tail, comb and wattle; yellowish legs and bold white spotting on underparts separate them from similar looking female Red Junglefowl. Quite noisy, their “kuk-ku-kuwuk-ku” calls are heard almost year-round.
