Forbes-Watson's Swift

Apus berliozi

Brownish, mid-sized swift with powerful, direct flight. The wings are uniform, without significantly contrasting paler patches on the inside of the wings. Nest in caves and crevices, but can be seen in flight over many habitats, especially dry, montane areas. The call is a moderately-pitched descending trill. Very similar to Pallid and Common Swift, and separation is difficult in times and places where they overlap. Slightly darker than Pallid Swift and paler than Common Swift, with subtly different vocalizations. Also similar to African and Nyanza Swifts, but can be separated by the uniform wings without contrastingly pale panels at the base.

Cape Teal

Cape Teal

Anas capensis

Medium-sized, pale gray duck with a pink bill. In flight, shows a green patch that is surrounded by white. Prefers saltwater wetlands such as natural saltpans and man-made saltworks but sometimes also uses freshwater wetlands. Similar to Red-billed Duck, but without a dark cap, and with paler overall coloration. Pink bill separates Cape Teal from all other ducks and grebes in the region.

Mikado Pheasant

Mikado Pheasant

Syrmaticus mikado

A stunning pheasant species endemic to Taiwan, the male a rich slaty blue with white markings and red facial skin, the female rich brown with extensive pale feather edges. Generally retiring, foraging quietly in the undergrowth of montane forests, but occasionally seen in the open, particularly in places where fed. Usually seen singly, in pairs, or in small family units (female with young). In breeding season, males drum with wings and give shrill whistling calls. Male lacks white back and tail of Swinhoe’s Pheasant; female has dark bill, grayish legs, pale markings below, and graduated, pointy tail, unlike female Swinhoe’s.

Red-shouldered Vanga

Red-shouldered Vanga

Calicalicus rufocarpalis

Small vanga that is built like a chickadee or tit. Male is colorful and female plain brownish. Madagascar endemic that is found very locally in spiny forest growing on limestone. Only described to science in the 1990s. Most common vocalization is a two- or three-part rising whistle. Separated from much more widespread Red-tailed Vanga by its pale eye and additional red on the shoulder.
