Black Sunbird
Leptocoma aspasia
A small songbird with a long downcurved bill. Male is blackish with iridescent areas: crown glossed greenish or blue, and shoulders, rump, and tail glossed with blue. Throat iridescent reddish-purple in most of range, but blueish in the north Moluccas and Kai islands. Female is nondescript, with a grayish head, white throat, olive upperparts, and yellowish underparts over much of range. In the south Moluccas and Aru islands, underparts are grayish. Juvenile resembles female, but yellower on throat. Inhabits forest edge, open forest, gardens, and scrub in lowlands and hills. Male can be separated from dark-bellied forms of male Olive-backed Sunbird by glossy, iridescent crown and black back. Females differ from Olive-backed Sunbird by absence of eyebrow, absence of white tail tip, white throat, grayish head, and duller yellow underparts. Females lack eye-ring, unlike larger female Brown-throated Sunbird, and are less uniform underneath than female Elegant Sunbird.
识别特征
It is a small songbird with a long down-curved bill and iridescent body. The black sunbird has a lifespan of approximately 3.6 years. The coloring of the birds differentiate between male and female. The male black sunbird is midnight black in color with an iridescent blue-purple stripe across the upper chest. There is a crown of lustrous green on the head, while the wings and tail are glossed blue. In many regions, the throat area is iridescent reddish-purple; however, moving northward it shifts towards a bluish sparkle (Moluccas and Kai Islands). The female black sunbird has a completely different color complex than her male counterpart. Her coloration across the chest and body is dusted greenish-yellow. The wings are smothered brown as well as the head. In northern areas, the color of the female black sunbird is "nondescript", with a charcoal colored head, with an olive-green upper-body and yellow underbody. The juvenile black sunbird resembles the female sunbird with more of a distinct yellow throat.

Rufous-winged Tanager
Tangara lavinia
Mostly green tanager, male deeper emerald with yellow back, mostly rufous head, and rufous wings. Female duller yellow-greenish but still with obvious rufous wings.

Common Firecrest
Regulus ignicapilla
Tiny bird, smaller than a warbler, with distinctive combination of boldly striped head, white wingbars, and bronzy-golden patch on sides of neck. Male has a fiery orange crown stripe; female's is yellow. Inhabits mixed forests, plantations, and gardens, usually in areas with conifers. In autumn and winter, often travels with foraging flocks of tits and other small woodland birds. Inconspicuous but active, often high in the canopy, giving high, thin, lisping vocalizations.
Great Gray Shrike
Lanius excubitor
Thrush-sized bird; pale gray overall with black mask. In flight, watch for white patches in the wings. In areas of overlap, compare with other gray shrikes. Inhabits open habitats with scattered vegetation, from open forests to bogs and brushy meadows. Often seen on prominent perches, including power lines and short treetops, that offer perfect vantages for from which to spot prey. Carnivorous habits make shrikes unique among passerines, feeding on rodents and small birds. Vocalizations include bright short liquid trills and “gargling” phrases, often strung together into a repetitive song.
