Yellow-billed Blue-Magpie
Urocissa flavirostris
The southwestern counterpart of the Red-billed Blue-Magpie, this colorful long-tailed corvid also forages in noisy flocks. Similar in coloration to Red-billed, but Yellow-billed is paler blue overall, with a small white patch at the back of the crown instead of an extensive white stripe, and a bright yellow bill instead of a scarlet one. Primarily found in Himalayan hill forest, with disjunct populations in northwestern Myanmar and northern Vietnam.

分布与栖息地
The yellow-billed blue magpie is found throughout the Himalayas from Hazara to the Brahmaputra. It is divided into two sub-species. Of these, U. f. cucullata is the more common and is found from the Western boundary of the range to Western Nepal, being common through most of the hill stations of the Western Himalayas, breeding in a zone from 1,500 to 3,000 m (4,900 to 9,800 ft). The eastern form is found from Eastern Nepal eastwards and differs in that the under parts have a darker lilac tinge; its zone is slightly higher than that of the Western form, and it seldom occurs as low as 1,830 m (6,000 ft). It is a resident species, but during the winter months it usually moves to lower elevations. From Simla eastwards, the closely related red-billed blue magpie (Urocissa erythroryncha) is often found in the same areas as the yellow-billed species; it is particularly common about Mussoorie, Tehri-Garhwal, -Kumaon, and in Nepal, and may be easily distinguished by its red beak and the greater extent of the white nape-patch.

行为
The blue magpies are primarily arboreal birds. While most common in areas of dense jungle, they can also be found in agriculture areas and bare mountain sides at higher elevation. They frequently feed on the ground and adopt a hopping gait with the tail held high to prevent it coming into contact with the ground. They live in parties of seven or eight birds and are highly territorial. The flight is slow and undulating once the bird comes into the open. The food consists of small mammals, the eggs and young of other birds, insects, wild fruits and berries. This bird is very vocal with a variety of vocalizations.<p>The magpies build their nests in the forks of trees in areas of heavy foliage. The large nests are constructed out of sticks and lined with grass and other fibers. The clutch consists of three or four eggs. The base-colour varies from a pale, dingy yellowish-stone colour to a darkish rather reddish-stone colour, and there is very occasionally a faint greenish tinge. The markings consist of small specks, blotches, streaks, and mottlings of various shades of brown, sienna 1 or purple, and they generally tend to collect in a cap or zone about the broad end of the egg.

Stripe-breasted Tit
Melaniparus fasciiventer
Typical tit with a black, white, and gray pattern. The black hood continues as a dark stripe down the center of the underparts. There are white edgings on much of the wing and the outer tail. Found in middle and high-elevation humid forest of the Albertine Rift. Usually in pairs or small groups, readily joining mixed-species flocks. Gives typical tit vocalizations including the classic “dree di-di-di” call and other whistled and chatty calls.
Emerald-chinned Hummingbird
Abeillia abeillei
Very small, short-billed hummingbird of humid evergreen and pine-evergreen forest in highlands and upper foothills; uncommon. Usually feeds low, often at banks of flowers along edges and roadsides. Feeding flight is usually quick and hard to follow. Best identified by small size, big white spot behind eye, and rather liquid twittering call (similar to Stripe-tailed Hummingbird, which occurs in the same areas but looks quite different).
Red-hooded Tanager
Piranga rubriceps
Striking bird of high elevation Andean cloud forest. Plumage is yellow with a strawberry red hood and dark wings; nothing similar occurs within its range. Male has a more extensive red hood than female. Uncommon and infrequently encountered. Pairs or small groups usually stay high in the forest canopy and may occasionally join mixed-species flocks. Gives short bursts of clear, high-pitched notes that can carry surprisingly far over mountain slopes.
