Black-and-yellow Tanager
Chrysothlypis chrysomelas
Small warblerlike tanager with striking color pattern: male brilliant golden-yellow with black back, wings, and tail. Female much duller and more olive-green with dirty whitish belly. Note bill shape: relatively long, slender, and pointed. A canopy bird, pairs or small groups are most often seen following mixed flocks in forests and edges.
识别特征
The adult black-and-yellow tanager is about 12 centimetres (4.7 in) long and weighs 12.5 grams (0.44 oz). The adult male has a bright yellow head, rump and underparts, and a black back, wings and tail. The wing linings are white. The male of C. c. ocularis differs in having a black spot on the lores. The female has olive upperparts and yellow underparts, but in Costa Rica and extreme western Panama (the sometimes recognized C. c. titanota) the throat and lower belly is whitish. She could be mistaken for a warbler or a female yellow-backed tanager. Immatures resemble the adult female.<p>The black-and-yellow tanager's call is a scratchy single or repeated tsew, higher and faster than that of the silver-throated tanager.
分类信息
Most authorities recognize two subspecies: The nominate in Costa Rica and western Panama and C. c. ocularis in eastern Panama, but some recognize the population in Costa Rican and extreme western Panama as a third subspecies, C. c. titanota (then limiting the nominate to the remaining part of western Panama). Some taxonomic lists modified the original name based on gender and use the specific name of chrysomelaena and this emendation is not considered correct.

分布与栖息地
In Panama it has been recorded as far east as the border-region with Colombia. In Costa Rica, the black-and-yellow tanager is found in the foothills and slopes on the Caribbean side of the central mountain ranges, typically from 600 to 1,200 metres (2,000 to 3,900 ft) altitude, and occasionally down to 400 metres (1,300 ft). In Panama, it is found on both the Caribbean and Pacific slope from 450 to 1,200 metres (1,480 to 3,940 ft). The preferred habitat is the canopy of wet forest and tall second growth, but it will feed lower at woodland edges and clearing. A family of black-and-yellow tanagers was reported in 2010 in Colombia's Chocó department, near the Panamanian border.

Pink Cockatoo
Cacatua leadbeateri
Distinctive cockatoo found in a wide variety of habitats across inland Australia, typically favoring dry woodlands, where it feeds on seeds. Relatively small, with pink underparts and white upperparts. Magnificent, long white crest has colorful band of red at base, in subspecies leadbeateri inset with another band of yellow. In flight, pink underwings evident. Often observed feeding on the ground beside roads. Call a wavering, high-pitched note.
Montane Double-collared Sunbird
Cinnyris ludovicensis
A medium-sized typical ‘double-collared’ sunbird with a long bill. Male has a very broad red breast band, bluish-violet rump patch, and a dusky belly. Female is dull gray-brown. Pairs and singles are common but extremely local in highland forests and thicket edges, restricted to distinct regions that perhaps represent three separate species: the Angolan scarp; Nyika Plateau of Malawi; and the Eastern Arc, Tanzania. Larger, with a broader red breast band on the male, than either Eastern Miombo or Forest Double-collared sunbirds; the latter also has an olive (not dusky) belly. Has a typical jumbled sunbird song.
Littoral Rock-Thrush
Monticola imerina
Chunky, mid-sized robin-like bird. Males are pale gray and orange, while females are gray-brown. Madagascar endemic that is found in coastal spiny forest and scrub in the southwest. Perches up conspicuously. Song is a variable mix of thin whistles and raspy notes. Paler than Forest Rock-Thrush, with little or no overlap in range. Female similar to female Madagascar Magpie-Robin, but smaller and grayer, without white patch in the wing.
