Yellow-browed Bulbul
Acritillas indica
Yellow-green bulbul with a clean face and dark eyes. Inhabits foothill and lower montane forests; often in moist areas. Commonly encountered in pairs or small flocks, but will also join mixed-species flocks. Typically sticks to cover. Song is comprised of cheery whistles mixed with slurred warbles. Calls include warbles, clear “weeeep” notes, and short nasal notes.
识别特征
This bulbul is about 20 cm (7.9 in) long, lacks a crest and has the upperparts olive-green with a prominent yellow brow and goggle with the underparts being all yellow. The sexes do not differ in plumage. The bill is black and the iris is reddish brown. The population in the northern Western Ghats (ssp. icterica) is paler yellow than the populations further south (ssp. indica). A somewhat disjunct population is found in the Eastern Ghats. Southwestern Sri Lankan populations (ssp. gugliemi) are greener while the northern populations are included in the nominate subspecies.
分类信息
The yellow-browed bulbul was originally described in the genus Trichophorus (a synonym for Criniger) in 1839 by T. C. Jerdon on the basis of specimens from the Wynaad region and given the original binomial (or protonym) of Trichophorus indicus. Formerly, the yellow-browed bulbul was classified in the genus Iole as two separate species but a study determined that this species is exceptional and it is now placed in the monotypic genus Acritillas. Some authorities have included the yellow-browed bulbul in the genus Hypsipetes but a 2018 molecular phylogenetic study indicated the nearest living relative as Hemixos flavala.<p>Three subspecies are currently recognized:

分布与栖息地
The yellow-browed bulbul has been considered as the wet-zone counterpart of the dry-zone white-browed bulbul. It is found mainly below the forest canopy of the hill forests and plantations in the Western Ghats and Sri Lanka. They also occur in parts of the Eastern Ghats including the Kolli hills, Nallamalas and parts of Tirupathi and Mamandur regions in Andhra Pradesh.

行为
Yellow-browed bulbuls are found in pairs or small groups and call loudly. They feed mainly on berries and insects. The breeding season is during the dry spell before the monsoons, mainly January to May. The nest is a cup built in a low fork covered with moss and cobwebs on the outside, giving the appearance of a large white-eye nest, and lined with fine root fibres. The typical clutch size in India is three eggs and in Sri Lanka two. A study of 153 nests in Silent Valley National Park of India found 92% of nests had two eggs. Peak breeding in the Silent Valley National Park of Kerala was found in January and February. About a week is taken for building the nest and the eggs are incubated for about 13 days. The eggs are pale pink or white with reddish brown speckling. The eggs hatch synchronously and the nestlings fledge after about 13 days. Nestlings are fed with caterpillars, soft insects and berries.

Somali Courser
Cursorius somalensis
A plain, pale courser with black lines behind the eyes that make a “V” when seen from behind. In flight, the wings are partially black with a white trailing edge. Found in dry savanna, thornscrub, and desert. Usually in small groups, which tend to flee from disturbance on foot. Very similar to Cream-colored Courser, but browner and shorter-winged, with partially pale rather than completely black underwings in flight. Fairly similar to Temminck’s Courser, but paler overall, lacks chestnut in the crown, and has a paler underwing. Calls include a quiet “whit” and a louder “trow.”
Zimmer's Tapaculo
Scytalopus zimmeri
Distinctive tapaculo of humid montane forest adjacent to treeline and Polylepis forest in the high Andes in NW Argentina and S Bolivia. Striking white throat distinctive from other tapaculos except White-browed, from which it differs by voice and gray (not brown) hind crown. Generally observed in the open more than other tapaculos, often perching on rocks and ground-level vegetation. Song a quick series two dry notes spaced out, then 3-4 quick dry notes: “pik-pik pr-tr-tr”.
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.
