Bornean Peacock-Pheasant
Polyplectron schleiermacheri
With his iridescent pale blue crest, bright orange facial skin patch, and luminous blue spots along his wings and broad fan-shaped tail, the eccentric-looking male is unmistakable if seen well. Female is less eye-catching: warm brown all over with smaller, darker spots. Inhabits primary lowland and hill forest, favoring areas with ridges. Typically quiet; occasionally gives loud, harsh calls.
识别特征
The pheasant is up to 50 cm long, rufous brown and black spotted, with an elongated crest and nape feathers, black below and bare red skin around bluish iris eye. The breast sides are metallic blue-green, bordering the white throat and central upper breast. Its twenty-two tail feathers are decorated with large blue-green ocelli, which may be spread fan-like in display. The female is smaller and duller brown than the male. It has a brown iris and no spurs on its feet.
分类信息
Together with the phenotypically similar Malayan peacock-pheasant and Palawan peacock-pheasant it represents a basal group in its genus; their radiation probably took place during the PlioceneBeing very poorly known, the Bornean peacock-pheasant was long considered to be a subspecies of the Malayan peacock-pheasant, but the two species are well-isolated geographically. The highly specialised anterior breast and upper neck plumage of male Bornean peacock-pheasant males are quite distinctive. Females of the two species are more difficult to distinguish. The rectrices of the Bornean species are morphologically and patterned intermediate between Palawan and Malayan peacock-pheasants.

Capped Heron
Pilherodius pileatus
This gorgeous medium-sized heron is uncommon but widespread in lowlands of South America, barely extending into eastern Panama. Not likely to be mistaken: combination of silvery back, buffy neck and belly, black cap, and blue lores (sometimes radiant turquoise!) help distinguish this species from other herons. Also note the long white plumes on the back of the head. Occurs around swamps, forested ponds, and rivers, usually singly.
Pere David's Tit
Poecile davidi
Like a Marsh Tit with a bright orange belly, this lively social bird is restricted to the mid-altitude mixed forests of central China. Usually moves about at middle levels in pairs or small flocks. Generally uncommon throughout its limited range, but once seen, can be tame and confiding. Vocalizations typical of small Poecile tits: various high chips, “tzit”s, and “chit-it-it” or “chit-zee-zee” calls.
Nubian Nightjar
Caprimulgus nubicus
Small and compact nightjar of vegetated semi-desert habitats. Overall rather pale sandy-brown, but note the distinctive rusty hind-collar and buff tips on scapulars and coverts when sitting on the ground. In flight flashes big white patches on wings and tail corners and wings appear relatively short and rounded. Also note the rich rusty underwing. Breeds under bushes, forages in open habitats, and often sits on tracks in the road. Vocalizations sound similar to a distant double-bark, "Kau-kau, kau-kau…"
