Black-fronted Bushshrike
Chlorophoneus nigrifrons
Pretty bushshrike that has four different morphs. These vary by the color of the underparts: white with a pinkish breast, a black breast and yellow belly, yellow with an orange center of the breast, or red with a yellow belly. Found in forest, mainly at middle and high elevations. Often joins mixed feeding flocks. The most common vocalizations are repeated bell-like notes and low rasps. Variable, but in all morphs, separated from other bushshrikes by black extending above the bill and by the lack of a pale eye stripe.
识别特征
It is 18-19 centimetres long. It is variable in appearance and has several different colour morphs. All birds have green upperparts, grey crown and upper back, yellow tip to the tail and dark bill and legs. The orange morph has a black mask and forehead and orange underparts, shading to yellow under the tail. The red morph is similar but redder on the throat and breast with yellow on the belly and undertail-coverts. The buff form has buff underparts and a pale throat. The black morph has an entirely black face, forehead, throat and breast and green belly and undertail-coverts. Females are duller than the males with less black on the forehead. Juvenile birds have buffish underparts with dark barring and yellow edges to the wing-feathers. The song includes repeated bell-like phrases. Pairs often duet together.

分布与栖息地
It has a patchy distribution and is restricted to montane forests in many areas. It forages in the canopy and middle levels of the forest and joins mixed-species feeding flocks outside the breeding season. There are three subspecies: C. n. nigrifrons occurs from central Kenya southwards through Tanzania to northern Malawi. C. n. manningi is found from the south-eastern part of the Democratic Republic of the Congo to northern Zambia. C. n. sandgroundi occurs in southern Malawi, Mozambique, eastern Zimbabwe and north-eastern South Africa.

St. Lucia Black Finch
Melanospiza richardsoni
A small seed-eating species of forests with dense understory. Commonly found in pairs feeding on the ground. Males are entirely jet-black, whereas females have a largely buff-brown body and a gray head. Females of the similar-looking Lesser Antillean Bullfinch are grayish below with a browner head. The male Lesser Antillean Bullfinch is mostly black but has a small red throat patch that male St. Lucia Black Finches lack. Both sexes of bullfinch also have a smaller bill than that of the black finch. Vocalizations include a high “tseea-ts-ts-tsew” and a slightly squeaky “tsip.”
Bare-eyed Antbird
Rhegmatorhina gymnops
Fantastic-looking antbird with a bold whitish bare eye-ring and a restricted range. Males have a black head and breast, and are otherwise cinnamon-brown; females are duller around the head, but otherwise also cinnamon. Occurs in the understory of humid forest, where almost invariably found attending army-ant swarms. Song is a short series of high descending notes, ending in a harsh “churr.”
American Bittern
Botaurus lentiginosus
Stocky, brown heron found in marshes and bogs. Usually secretive and difficult to see, but occasionally found in the open. Most similar to juvenile night-herons. Note striped neck, plain unspotted wings, and even more secretive behavior of bittern. Most active around dawn and dusk, when it might be seen flying low over extensive marshes. Listen for its incredible vocalization in the spring and summer: a resonant, booming noise produced by air sacs on the neck, “oonk-GA-loonk.” Also gives single low squawks.
