Phaethornis yaruqui
Large, dark hermit with an extremely long curved bill. Dark greenish overall with a buffy eyebrow and a white mustache. Also note long graduated tail with a white tip. Generally common in lowland and foothills, up to around 1,300 m. Found within forests and also in second growth and gardens where it visits feeders. Stays low, quickly zipping around flower patches in the understory.

分布与栖息地
The white-whiskered hermit is found from Colombia's northern Chocó Department south through western Ecuador to El Oro Province. It has also been reported in Panama near the Colombian border. It inhabits humid mid-elevation and montane forest, humid secondary forest, dense shrublands, and plantations. In elevation it usually occurs below 1,200 m (3,900 ft) but has been recorded as high as 2,000 m (6,600 ft).<p>

行为
The white-whiskered hermit is primarily sedentary but apparently makes seasonal elevation movements in Ecuador.<p>The white-whiskered hermit is a "trap-line" feeder like other hermit hummingbirds, visiting a circuit of a wide variety of flowering plants for nectar. It also consumes small arthropods.<p>The white-whiskered hermit's breeding season has not been described, though it appears to span from November to July. The nest is a cone-shaped cup suspended from the underside of a drooping leaf. The clutch size is two eggs.<p>The white-whiskered hermit's song is "a continuous series of rather harsh 'kree-u' notes". It also gives a series of "seek" notes while wagging its tail on a low perch at a lek.

White-crowned Shama
Copsychus stricklandii
Black with an orange belly and bright white crown; also note white rump and undertail. Endemic to northern Borneo, where it inhabits lowland and foothill forests, including swamps and around streams. Typically forages on or close to the ground. Loud, vibrant song is beautiful and variable, consisting of a range of whistles, warbles, and harsher notes.
Seychelles Paradise-Flycatcher
Terpsiphone corvina
Unusual and distinctive paradise-flycatcher. Adult males are completely glossy blue-black with extremely long tail streamers. Female has a black head, rufous upperparts, and white underparts, and lacks tail streamers. Both sexes have a blue ring of bare skin around the eye. Endemic to the Seychelles, where it is found mainly on the islands of La Digue and Denis. Habitat is thick indigenous woodland. A restless, active bird of middle levels of the forest. Calls include a tearing “shreeet” and an agitated twittering. The song is a long, musical, slightly descending series of “twee” notes.
Cerulean Warbler
Setophaga cerulea
Brilliant sky-blue warbler of the high canopy. Prefers mature deciduous forest, either in riparian areas or dry mountain ridge-tops. Tends to stay high in the canopy; thus, can be difficult to see blue color. From below, look for white throat and belly, thin necklace, and dark streaks on sides. Female is a unique muted turquoise with pale eyebrow and blurry streaks on sides. Immature birds show yellow wash on underparts. All plumages have bold white wingbars. Easiest to detect in spring and summer by its loud buzzy song, similar to Black-throated Blue but usually richer and more distinctly three-parted; much lower-pitched than Blackburnian Warbler. Winters primarily on the east slope of the Andes from Venezuela to Bolivia.
