Yellow-footed Honeyguide
Melignomon eisentrauti
Medium-sized honeyguide with a plain face, a slim pale bill, yellow legs, and large white patches in the outer tail. Found in the middle levels and canopy of humid forest at low and middle elevations. The distinctive vocalization is a series of around a dozen rising “sveeya” notes. The series slows down and becomes slightly lower-pitched at the end. Very similar to Zenker’s Honeyguide, but there is only minor overlap in range, and Yellow-footed is paler overall with more white in the tail. Similar to other honeyguides, but separated by the slim bill and the yellow legs. Separated from most greenbuls by the white in the tail, and from Honeyguide and Sjöstedt's Greenbuls by the smaller size and shorter tail.
识别特征
This small, unobtrusive bird grows to a length of about 18 cm (7 in). The sexes are similar in this species but females are slightly smaller than males. The head and upper parts are olive green, with the back rather yellower than the head. The flight feathers of the wings and the two central feathers of the tail are brownish-black, as are the bases of the outer four pairs of feathers, the remainder being white, with dark tips. The chin, throat, breast and front of the belly are pale grey, while the rear belly and the under-tail coverts are pure white. The beak is yellowish, the orbital ring greenish-yellow and the iris brown. The legs and feet are yellow. The voice is a sequence of about a dozen clear notes, each rising in pitch, the whole series gradually slowing and descending.

行为
This bird feeds on insects, fruits and seeds, and probably on beeswax as evidenced by a waxy yellow material being found among the stomach contents. Little is known of its breeding behaviour.
保护状况
The yellow-footed honeyguide occupies a total area of around 485,000 km2 (187,000 sq mi) and is described as being rare, although this may be because it is an unobtrusive bird. It is threatened by habitat destruction, as the forests where it is found are being degraded or cleared, but it is tolerant of some degree of habitat disturbance. For these reasons, the International Union for Conservation of Nature suspects that its population is slowly declining and has assessed the species as having a "near threatened" conservation status.

Javan Myna
Acridotheres javanicus
Originally restricted to the Indonesian islands of Java and Bali, this crested myna has since been introduced to Singapore, Taiwan, and various parts of Malaysia and Indonesia. Dark gray overall with a spiffy erect crest and a bright yellowish-orange bill. Darker than Jungle Myna, with which it overlaps in both its native and introduced ranges. Also compare with Crested Myna; note Javan’s brighter bill and white vent. Bold and social, foraging in farms, parks, and gardens. Roosts in large noisy flocks, often close to human habitation.
African Black Duck
Anas sparsa
A chocolate-brown duck with unmarked underparts, a pale-pink-and-black bill, orange legs, and white spots on the back and rump. A secretive and uncommon resident, preferring well-wooded, fast-flowing rivers but also visiting ponds. It forages mainly at dawn and dusk, dabbling for insects and plant matter. Differentiated from the similar Yellow-billed Duck by darker coloration, shorter neck, and dark, not vivid yellow, bill.
Butterfly Coquette
Lophornis verreauxii
Tiny hummingbird with a white rump band and rusty tail. Adult male is stunning, with a flowing, glittering green beard ending in white spots, an iridescent green face, and a small crest. Female and young male are much plainer than male, but they typically have a white throat with dark patch in the middle, and lack the buffy or rusty tones on the underparts shown by females of several similar species. Distinguished from female Peacock Coquette by lack of streaking on the throat. Inhabits humid lowland and foothill forest and is quite scarce in most of its range. It was previously considered to be a subspecies of Festive Coquette.
