Grosbeak Weaver
Amblyospiza albifrons
A large dark weaver with a massive bill. The male is brown with a dark bill and a white dash on the forehead and wing. The female has a pale bill and is heavily streaked underneath. Pairs are resident, breeding in wetlands and rank areas adjacent to well wooded groves and forest; flocks form in the non-breeding season. The species feeds on fruit and insects in the canopy and on the forest floor. The song is a rapid high-pitched warble that includes multiple sputtering trills, for example “pit-pit-pit-pit chweeer-kuuuurrrr”.

分类信息
The generic name Amblyospiza was coined by Carl Jakob Sundevall in 1850 and means "blunt, finch", referencing the very large bill, while the specific name albifrons refers white forehead of the males. The thick-billed weaver was formally described as Pyrrhula albifrons in 1831 by the Irish zoologist and politician Nicholas Aylward Vigors from the collection of Henry Ellis, the specimens of which were attributed to Algoa Bay and environs in the Eastern Cape.<p>Ten subspecies are currently recognized:

Black-faced Babbler
Turdoides melanops
Dull brownish babbler with a pale eye. Found very locally in areas of thick mixed savanna. Almost always in small groups, which feed by hopping across the ground. Raucous babbling call is frequently given, usually by a whole group in chorus. Similar in shape, size, and overall brown coloration to Arrow-marked Babbler, but easily separated by pale eyes, black lores, and broad and messy markings below. Also easily separated from Hartlaub’s Babbler by the white eye and dark rump.
White-capped Dipper
Cinclus leucocephalus
The only dipper in its range, and thus unlikely to be confused. Chunky and boldly patterned in blackish and white, with obvious white crown and underparts (somewhat variable in different parts of range). Sexes similar. A denizen of fast-moving streams and rivers with plenty of rocks to perch on. Fairly widely distributed in the Andes from Venezuela to Bolivia; can be found from 700–3,500 m. Usually seen singly or in pairs, quite conspicuous as they perch on boulders or fly along the river. Gives a piercing “dzeet!” call, especially in flight.
Pale-yellow Robin
Eopsaltria capito
A rotund little robin, olive above, with gray head, yellow underparts, and white around the base of the bill. Perches on low branches and on the side of tree trunks, from which it drops to the ground to capture prey. Similar Eastern Yellow Robin is brighter yellow below and has gray lores. Inhabits rainforests in the wet tropics of far northern Queensland and eastern Australia.
