Little Spotted Kiwi
Apteryx owenii
New Zealand’s smallest kiwi species. Light grayish brown with white horizontal banding or “spotting” along the length of the body. Restricted to offshore predator-free island sanctuaries and to the mainland Zealandia sanctuary in Wellington. More often heard than seen, including loud sniffling as it forages for invertebrates. Male produces a series of burry, rising high-pitched whistles. Female has a lower ascending burry whistle. Both sexes repeat their call many times, often duetting. Could be confused with Weka by voice and shape; look for the kiwi’s much longer bill and lack of tail, and listen for its multisyllabic call.
识别特征
The little spotted kiwi has a length of 35 to 45 cm (14–18 in) and the weight of the male is 0.88 to 1.36 kg (1 lb 15 oz – 3 lb 0 oz) and the female weighs 1 to 1.95 kg (2+1⁄4–4+1⁄4 lb), making it the smallest species of kiwi. Their feathers are pale-mottled grey, with fine white mottling, and are shaggy looking. They lack aftershafts and barbules. They have large vibrissae feathers around the gape. They lack a tail, but have a small pygostyle. Their bill is ivory and long and their legs are pale.
分类信息
The little spotted kiwi is a ratite and belongs to the Apterygiformes order, and the Apterygidae family. The genus name Apteryx means 'without wings' and the species is named owenii after Sir Richard Owen. Only the nominate subspecies A. o. owenii survives. The subspecies A. o. iredalei from the North Island became extinct in the late 19th century; its status as a subspecies is not universally accepted as valid though.<p>The little spotted kiwi was first described in 1847 by John Gould from a specimen obtained by Frederick Strange and sent to England. The locality is not recorded but it probably came from Nelson or Marlborough. In 1873, Henry Potts published an account of its habitats, and about this time specimens were collected in South Westland and sent to England.

分布与栖息地
Studies on Kapiti Island show that they prefer flax, seral, and older forest habitats. Lower numbers are found in rough grassland and scrub, indicating that either they prefer other habitats or they simply need a larger territory to support themselves in these areas.

Austral Negrito
Lessonia rufa
Tiny little terrestrial flycatcher, common in open habitats of southern South America in summer, migrates north in winter. Feeds mainly by hopping on the ground, but perches readily on posts, fences, and low bushes. During migration times, sometimes found in small flocks mixed with other migrants of open country. No similar species in range: male is black with bright rusty back. The much plainer female is easily overlooked, but size, shape, and behavior distinctive, and is often with males.
Stiles's Tapaculo
Scytalopus stilesi
A standard Scytalopus tapaculo: plain dark gray with browner flanks and rump. Acts like a mouse, scurrying around on or near the ground within montane forest. Extremely limited range in the central Andes of Colombia. Far more often heard than seen. Listen for froglike churring song, given as a long series of short bursts.
Black-faced Cormorant
Phalacrocorax fuscescens
Large black and white cormorant with dark face, white flanks, and black "trousers." Very similar to Pied Cormorant; note present species' black lores and chin. Almost exclusively found in marine environments, and unlikely to be seen away from the ocean.
