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.

Black-bellied Firefinch
Lagonosticta rara
Males are mostly pinkish-red, and females have a brown back, a gray head, and pinkish underparts. Both sexes have a dark bill with a pinkish area at the base, an extensive black belly, and no white spots on the underparts. Found along forest edge and in overgrown cultivation, lush savanna, and scrub. Usually in pairs or small groups, sometimes mixed with other waxbills. Similar to several other firefinches, but separated by the lack of white spots below. Male further separated from similar species by the all-red head. The song is a series of low whistles, and the calls include “chet” notes and a short trill.
Fraser's Eagle-Owl
Ketupa poensis
Medium-sized rufous-brown owl, with long ear tufts. Note the dark eyes, rufous face, and cleanly barred underparts. Found in and around humid forest. The main vocalization is a long, haunting whistle that first rises, then falls and fades. Secondary vocalization is a low, rapid, pulsating series of hoots. Similar in shape to Akun Eagle-Owl, but has dark rather than yellow eyes, more rufous coloration, and cleaner markings on the underparts. Also similar to Spotted Eagle-Owl, but much more richly colored, with darker eyes.
Rufous-bellied Euphonia
Euphonia rufiventris
Small finch-like bird of lowland rainforest. Male is glossy navy blue with a deep red-orange belly, fairly distinctive in its range; female is golden with gray wash on the head, back, and belly, and orange-red undertail coverts. Females similar to females of Orange-bellied Euphonia, but usually have deeper orange or red undertail coverts (not yellow). Found in humid forests, where often one of the most common euphonias. Frequently heard giving a rapid, deep chatter “chree-chree-chree-chree.”
