Black-capped Bulbul
Rubigula melanictera
Medium-sized greenish bird with a bright yellow underside and black head. Occurs in a variety of habitats, wherever there are trees, including forest, open woodlands, and gardens, in the lowlands and foothills. Usually encountered in pairs or small groups. Yellow throat and lack of black in the wing separates this species from Black-hooded Oriole. Unmarked, black head identifies Black-capped Bulbul from Yellow-eared and Yellow-browed Bulbuls. Song is series of warbling whistles, rising at the end, “wet-wet-wet-wer-wer-wer-weer.” Also gives churring calls.
识别特征
The black-capped bulbul is virtually crestless and has a yellow throat and brownish eyes. It is yellowish green above and yellow below. The tail is brownish and ends in a white tip. The male has red irides and the female has brown irides. Calls include a broad repertoire of sweet, mellow, minor-key piping whistles and sharper calls. Breeding records are from March to September.
分类信息
The black-capped bulbul was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with the flycatchers in the genus Muscicapa and coined the binomial name Muscicapa melanictera. The specific epithet combines the Ancient Greek melas meaning "black" with ikteros meaning "jaundice-yellow". Gmelin based his description on the "yellow-breasted fly-catcher" from Sri Lanka that had been described and illustrated in 1776 by the English naturalist Peter Brown.<p>The black-capped bulbul was formerly placed in the genus Pycnonotus. A molecular phylogenetic study of the bulbul family published in 2017 found that Pycnonotus was polyphyletic. In the revision to the generic classification the black-capped bulbul and four other species were moved from Pycnonotus to Rubigula.Until 2008, the black-capped bulbul was considered as conspecific with the black-crested, ruby-throated, flame-throated and Bornean bulbuls. Some authorities have considered the ruby-throated, flame-throated and Bornean bulbuls to be subspecies of the black-capped bulbul.

Yellow-billed Egret
Ardea brachyrhyncha
A stocky egret that is larger than Western Cattle and Little Egrets, but smaller than the Great Egret. Often confusing and difficult to identify, this bird is truly intermediate between potential confusion species. Things to look for include a yellow bill (brighter during breeding season) that is shorter than Great Egret but longer than Cattle Egret, a relatively rounded head, and shorter legs than Great Egret, approaching Cattle Egret. Like most egret species, associates with all types of water bodies including wet fields, often flocking with other egrets.
Stripe-cheeked Greenbul
Arizelocichla milanjensis
Large chunky, olive-green greenbul. The crown is gray, and there is a white arc above the eye, and a dark cheek with fine white stripes, though these can be hard to see. Found in humid foothill and montane forest. The song is a chatty, up-and-down series of low “chowp” notes and higher nasal notes. Similar to Black-browed Mountain Greenbul, but has cheek striping, and greenish rather than grayish underparts.
Blue Jay
Cyanocitta cristata
Familiar but stunning jay found year-round throughout most of eastern North America. Bright blue above and pale gray below with a fluffy crest. Also look for black necklace and black and white markings on the wings and tail. Pairs or small groups travel through mature deciduous or coniferous woodlands, often revealing their presence with loud, harsh “jay” calls. Frequently visits bird feeders, where it is often aggressive towards other birds.
