Bearded Woodpecker
Chloropicus namaquus
A large and long-billed woodpecker with a pale-barred gray-olive belly and a bold facial pattern: the crown is black in the female and black (forecrown) and red (hindcrown) in the male. It forages solitarily or in pairs, preferring dead and decaying trunks where it can excavate for beetle larvae and other insects within savanna and riverine forest. It calls a sharp “kwip-kwip-kwip” and gives a characteristic drum that lasts about 5 seconds, beginning fast and then slowing. The similar Golden-crowned Woodpecker differs by occupying rainforest, having spotted (not barred) underparts, and having a yellow hindcrown patch in the male.
识别特征
The bearded woodpecker is one of the largest woodpeckers in Africa growing to a length of about 25 cm (10 in). The head is distinctive with a black moustache, a broad black eye-stripe and black crown contrasting with a white supercilium, face, chin and throat. The male has a red hind crown which the female lacks. The mantle is black and the rest of the upper parts are yellowish-brown with narrow white barring. The tail is brown, barred white, the feathers having yellowish shafts. The underparts are grey with narrow white barring. The beak is large and greyish-black, the legs grey and the eyes red. Juveniles are similar to adults but the upper parts have a greenish tinge and more diffuse barring, and both sexes have some red colouring on the crown and nape.

行为
The bearded woodpecker often forages in pairs which communicate with each other vocally, flicking their wings as they call. Each bird will spend a long time on a single tree, hammering, probing and pecking with its beak and gleaning any stray insects it encounters, before flying off to another, often distant, tree. The diet consists of insects and their larvae, spiders, caterpillars and ants. It has been known to catch geckos and small lizards. This bird often drums loudly on branches, finishing each drum-roll with four taps. The nest hole is drilled in dead wood, up to 20 m (70 ft) above the ground. A clutch averaging three eggs is laid and incubation, by both parents, lasts thirteen days. The chicks are cared for by both birds and remain in the nest for about four weeks.

Black-bellied Bustard
Lissotis melanogaster
A lithe, medium-sized bustard with black daubs on a mostly tan-colored back. The male has a black belly, neck stripe, throat, and face patch. The female is uniform buff-brown from the belly to the head. In flight, both sexes have white windows in the wings. Singles and pairs inhabit tall grassland and grassy savanna. Its strange display involves the male stretching his neck and making a frog-like “kwoork” croak, and as he retracts his head to the shoulders, follows with a “grrrr” growl and champagne-cork-like “pop” while his head lifts again. He also performs an aerial display with the wings held back rigidly and with a puffed throat exposed.
Black-cheeked Mountain Tanager
Anisognathus melanogenys
Large, colorful tanager found only in the Santa Marta Mountains of Colombia. Note the black mask, yellow dot behind eye, and azure crown; plumage is otherwise blue and yellow. Usually seen in the canopy of cloud forest, often in pairs, and regularly joins mixed species flocks. It is rather quiet for a mountain-tanager, and typically just gives soft chip notes. Quite common in the upper parts of El Dorado Nature Reserve.
Blue-gray Robin
Melanodryas cyanus
A fairly small bird of montane forest. Blue-gray plumage, with contrasting blackish wings and tail. Perches low down, often on diagonal branches or vertical mossy trunks, flicking its tail and scanning the ground for insects. Very similar to Smoky Robin, but Blue-gray has a distinct bluish tinge to the gray, lacks the paler belly and has more contrasting black wing feathers. Several different vocalizations, including mournful, monotonous whistles, an up-and-down, whistled jumble and a rasp.
