Bearded Barbet
Pogonornis dubius
Large, colorful barbet with a huge ivory-colored bill. Note the red underparts with a thick black bar across the middle. Found in a variety of habitats, including moist and dry savanna, woodland, gardens, and secondary growth, often in the vicinity of figs and other fruiting trees. Most often in pairs or small groups. The call is a very rough, explosive “rwauk,” often given in a slow series. Similar to Double-toothed Barbet, but separated by the black chest band and the lack of a red bar on the shoulder.
识别特征
This is a conspicuous, large barbet at 26 centimetres (10 in) in overall length. It is fairly plump, with a short neck, large head and a shortish tail. The adult has a black crown, back, tail and breast band. The throat and belly are red and there is a yellow eye patch. The rump is white. The massive bill is very thick and yellow, and the well developed clump of bristles at its base give the species its name. Sexes are similar. The call is a growling scrawk.
分类信息
The bearded barbet was formally described in 1788 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with the puffbirds in the genus Bucco and coined the binomial name Bucco dubius. The specific epithet is Latin meaning "doubtful" or "dubious". John Latham had earlier included the species in his work A General Synopsis of Birds and had written "This bird inhabits the Coast of Barbary, and if of doubtful genus". Both Gmelin and Latham based their description on "Le Barbican" that had been described and illustrated in 1780 by the French polymath Comte de Buffon. The bearded barbet is now placed with 12 other barbets in the genus Lybius that was introduced in 1783 by the French naturalist Johann Hermann. The species is monotypic: no subspecies are recognised.

Bare-cheeked Trogon
Apaloderma aequatoriale
A trogon of lowland rainforests, almost always found in the forest interior, away from forest edges. Males and females have distinctive bare yellow facial skin below their eyes and between their eyes and bill. Both sexes have green backs and uppertails, red chests and vents, and finely barred wings. The species often calls motionless in the subcanopy, giving a series of 6-10 sad, descending coo notes, repeating these series 2-3 times per minute. Similar to the larger Narina Trogon, but Bare-cheeked Trogon is told apart by its song, its closed-canopy forest habitat, and the purely green tones on its head, back, and uppertail.
Scrub Honeyeater
Meliphaga albonotata
A medium-sized honeyeater of foothill and mid-mountain scrub. Uniform olive green with a white ear spot and indistinct streak in the base of the bill. Some geographical overlap with the similar Forest Honeyeater, the only other similar species with a white ear spot, but Scrub Honeyeater has more green in the wing and is usually in scrub rather than forest interior. Call, a “chup!” similar to other similar species or a rapid series of whistles.
Rufous Babbler
Argya subrufa
Large rufous-brown babbler with a long tail and white eyes. Pale gray forehead evident if seen well. Not as bold and pugnacious as some of its close relatives; typically forages in dense undergrowth in foothill forest and forest edge, often in wetter areas than Jungle, Common, and Large Gray Babblers. Gives distinctive rising rattle-whistles: “trriIIII! trriiiIII!”
