Soft-plumaged Petrel
Pterodroma mollis
Attractive petrel with a black mask, largely gray above and white below, with a diagnostic dark breast band. Note the heavy dark bill. In flight, exhibits gray underwings and gray and dark brown M-pattern on the back. The rare dark morph has dark underparts, but still retains the distinctive complete breast band, which is the most useful mark separating this species from Fea’s and Zino’s Petrels. Usually encountered well offshore, in towering roller-coaster flights; sometimes follows boats.

The soft-plumaged petrel is a medium-sized petrel. Its plumage is dark grey and white, and its wings are narrow and with a pointed tail distinct in flight. It has a dark grey head with prominent white feathers on the cheeks and throat. There is a white speckling on forehead along with a prominent dark eye patch. Its underside is mostly white, which turned dark grey at underwings. The bill is black and about 25–32 mm long and has a sharp hook. Its legs are pink with black on the outer webs and toes. There is also the dark morph, which is another variation of the petrel.<p>Both sexes are noisy, making medium-pitched moans and shrill squeaks.

其他鸟类
Pennant-winged Nightjar
Caprimulgus vexillarius
Breeding males have extraordinary “pennants” growing out of their wings. Non-breeding males are still distinctive due to the huge white patches on the wings. Females are very drab, and lack white in the wing or tail, unlike most nightjars. This is a migratory species that is found in many different habitats on migration and during the non-breeding season. Breeds in moist savanna and broadleaved woodland, especially miombo. Song is a slow, squeaky trill. Female is similar to Standard-winged Nightjar, but is larger and has more barring in the wings.
Long-tailed Minivet
Pericrocotus ethologus
Typical colorful minivet with red-and-black males and gray-and-yellow females. Male is very similar to Scarlet and Short-billed Minivets, but has a lumpy fork on the wing instead of a jagged ‘lightning bolt’ as in those two species. Female can be identified by a similarly simple wing patch and less extensive yellow on the head than Short-billed and Scarlet Minivets. Both sexes average longer-tailed than similar species. Usually found in pairs or small flocks in mid- to high-altitude forests. Gives a pleasant “dee-dee” and a rolling “pr’wee, pr’wee!”.
African Pygmy-Goose
Nettapus auritus
Colorful miniature waterfowl that is smaller than most ducks. Both sexes have rufous underparts, a dark back, white on the face, and white on the wing in flight. Males have a green patch on the back of the head and a yellow bill; females have a black-and-white head and a dark bill. Found in freshwater wetlands with floating vegetation, especially water lilies. Shy and inconspicuous, as it generally avoids open water. Voice is a high-pitched squeaking. Small size and bold and colorful plumage separate it from other waterfowl.
