Black-capped Foliage-gleaner
Philydor atricapillus
Medium-sized foliage-gleaner with a strong head pattern. Uniformly warm rufous apart from a black cap and pale check patch framed by two black lines. Found in humid lowland forests where it usually accompanies mixed-species flocks and forages at all levels. The song is a loud descending trill; also gives metallic “priew” notes.
识别特征
The black-capped foliage-gleaner is 16 to 17 cm (6.3 to 6.7 in) long and weighs 17 to 27 g (0.60 to 0.95 oz). The sexes have the same plumage, with a very dramatic facial pattern. Adults have a wide pale buff eyering, a pale buff supercilium that is more orange-rufous to the rear, a blackish-brown band behind the eye, dull buffy rufous lores, and pale buff ear coverts with blackish-brown bands above and below them. Their crown is dark brown with faint spots on the forehead and faint streaks in its center. Their back is rich rufous-brown, their rump slightly paler but more rufous, and their uppertail coverts bright orange-rufous. Their tail is bright rufous. Their wings are mostly rich brown with darker coverts and dark fuscous tips on the flight feathers. Their chin, throat, and malar area are light orange-rufous. Their breast and belly are plain dark orange-rufous; their flanks are slightly duller and their undertail coverts bright rufous. Their iris is brown, their maxilla blackish, their mandible pale gray to greenish gray, and their legs and feet pale ochre-yellow to light olive-gray. Juveniles are much like adults but with dark brown edges on their underparts' feathers.

行为
The black-capped foliage-gleaner is a year-round resident throughout its range.<p>The black-capped foliage-gleaner feeds on a wide variety of adult and larval arthropods with a preference for adult Lepidoptera. Lesser components of its diet include Coleoptera and spiders, and it seldom feeds on ants. Single birds and pairs often join mixed-species foraging flocks, feeding at all levels of the forest from its understory to its canopy. It acrobatically works its way along branches, gleaning and pulling prey live and dead leaves, bark, debris, and bark crevices. It especially favors bromeliads as prey sources.<p>Almost nothing is known about the black-capped foliage-gleaner's breeding biology. Anecdotal reports place its nest in a hole in an earthen bank.<p>The black-capped foliage-gleaners song is "a somewhat musical, whistled, fast, sharply descending trill" described in more detail as a "rapid series of 6-8 very high notes, the 1st 2 lower...the last 2 slightly lower still". Its calls include an "irregular series of squeaky notes, and 'pit-wit' " and a "very high, metallic sounding 'zic' ".

Scarlet-breasted Fruiteater
Pipreola frontalis
Plump, colorful bird of cloud forest along the east slope of the Andes. Plumage is mostly green and yellow, and male has a red throat and breast. Female may have a yellow or orange chin patch, but this feature is often absent on Ecuadorian birds. Female is similar to female Fiery-throated Fruiteater but larger and with an orange (not black) bill. Plucks berries at mid-levels in the forest, and often found in pairs. Gives high-pitched chips and whistles, sometimes followed by a trill.
Large Niltava
Niltava grandis
Typical niltava: male bright blue, female plain brown. Male is bright electric purplish-blue above and very dark blue below. Female is dark brown with rusty tones in the wings and an iridescent blue patch on the neck. Southeast Asian females have a pale powder-blue crown and nape. Lack of a bright white throat patch separates female from female Rufous-bellied and Fujian Niltavas. Small Niltava is similar in plumage, but much smaller and less heavyset. Male White-tailed Robin can be surprisingly similar but is proportionally smaller-headed and larger-bodied and has a wider tail with two bright white patches on it. Inhabits dense submontane forests, where it can be difficult to spot in dense foliage; often encountered making forays from a perch. Song is an ascending series of 3-4 short, highly musical whistled notes.
Philippine Falconet
Microhierax erythrogenys
A small raptor of foothill forest that favors exposed branches on emergent trees, often near rivers. Black above with a bluish sheen and a black base to the undertail that extends to the thighs and sides. The rest of the underparts are white, extending to the white cheeks. Unmistakable, as there are no other raptors of this size or birds with this color scheme. Voice is a descending, mouse-like squeak, “wiiuuu!”
