Bar-tailed Trogon
Apaloderma vittatum
Typically beautiful green-and-red trogon. The bottom of the tail is heavily barred black-and-white, and this pattern can also be seen along the edges of the top of the tail. Found in moist montane forest. Usually seen singly or in pairs. Quiet and inconspicuous bird of the mid-story. Usually detected by song: a series of 6-15 downslurred “teew” notes, which becomes louder as the series progresses. Separated from other African trogons by the barred tail.
识别特征
The bar-tailed trogon averages about 28 centimetres (11 in) long. The bill and feet are yellow, and the tail, long and broad as usual for trogons, has the underside narrowly barred with black and white. The male's head is blue-black with bronze iridescence. Below the eye are two yellow or orange patches of bare skin; above the eye is a yellow or grey patch. The upper breast is iridescent from violet to blue-green; the rest of the underparts are red. The back is green and the upper surface of the tail is blue-black or purple-black. The female's head is brown with less ornamental bare skin and its throat and breast are light cinnamon; otherwise it resembles the male. The immature is similar to the female, but has a white belly and pale spots on the wings formed by the tips of the wing coverts and inner secondaries.<p>The vocalisations are described as a yelping crescendo, "yaow, yow, yow, yow… or wuk-wuk-wuk-wuk…." The female gives "a whining chee-uu".

Gray-winged Blackbird
Turdus boulboul
A large forest thrush whose name describes its key feature; males are black and females are brown, but both have flashing silvery wings. Bright orange bill and eyering are eye-catching in dark forests. Forages quietly in the understory of montane and submontane broadleaf evergreen forests. Often solitary, occasionally in flocks in the winter. Tends not to visit gardens and parks like Tibetan and Chinese blackbirds, but does occasionally visit feeders at hides. Sweet, “thrushy” song consists of warbled phrases, sometimes with a slightly scratchy quality.
Chinspot Batis
Batis molitor
A cute, dumpy, colorful flycatcher-like bird lacking chestnut in the wings. Sexes differ: the male has a broad black chest band and a white throat; the female has a chestnut band and a large chestnut throat spot that gives the species its name. The Chinspot Batis is common in savanna, broadleaf woodland, and edges of montane forest, where it can be found solitarily or in pairs, often joining mixed-species flocks. It flits actively between trees, gleaning and hawking insects. Gives a characteristic downslurred three-note “three-blind-mice” call, which is occasionally accompanied by clicking and bill-snapping.
White-bellied Minivet
Pericrocotus erythropygius
A beautiful minivet inhabiting open, dry scrub and savanna with scattered acacia (Prosopis) growth. The male has a glossy black upper body, face, and neck. The breast region has a round orange patch, with the rest of the underparts white. The tail is black, with an orange rump and white markings on the wings. The plumage of the male of this bird is reminiscent of breeding male stonechats. The female is duller in appearance, with dark gray upperparts, black wings, a black tail, and dark black lores. The wings have white markings similar to the males’, and the rump is orange. The species usually moves in small groups, feeding mainly on insects.
