White-thighed Hornbill
Bycanistes albotibialis
A large canopy hornbill with a distinct white-tipped tail, a broad white outerwing with white patches within the black forewing, a white belly and vent, and a pale bill. Often seen in the canopy and subcanopy of lowland forest feeding on fruit. Call is a harsh series of caws, “hyr hyr hyr,” with occasional longer wails. Most likely to be confused with Black-and-white-casqued Hornbill, but White-thighed Hornbill has white on the vent and rump and on the tail tip, giving its tail a black-banded appearance, and its bill is pale.

Fruit-hunter
Chlamydochaera jefferyi
Handsome and unmistakable thrush. Male is gray overall, whereas female is suffused with rusty cinnamon-brown. On both sexes, note prominent black bib, slender black mask which wraps around the back of the head, and black wingtips. Endemic to Borneo’s highlands, where it wanders nomadically through submontane and montane forests in search of fruiting trees. Often encountered in pairs or small groups, foraging at middle and lower storeys of forest. Generally quiet; gives high thin “tsiiiii.”

Purple Sunbird
Cinnyris asiaticus
The breeding male is a metallic blue and purple overall with maroon feathers on the breast. The female is olive above and yellow below. The nonbreeding male of this species is primarily olive-brown with blackish upperparts and yellow underparts with blue-black band running down the throat and chest. Females can be distinguished from female Purple-rumped Sunbirds by its yellow (not grayish) throat. Seen in pairs, feeding chiefly on nectar, but they also take insects. Breeding males display by fluttering their wings in front of females while singing. They are found in gardens, cultivated areas, and forests.

Boyer's Cuckooshrike
Coracina boyeri
A medium-sized bird of lowland forest canopy. Blue-gray plumage with darker wings and tail, and slightly paler head. Male has a black face. Similar to male Common and Gray-headed, plus female Papuan and Black-bellied Cicadabirds, but Boyer’s has a paler head, stubbier bill and rufous underwings. Also similar to Stout-billed Cuckooshrike, but much smaller and shorter-tailed. Voice, long, piercing, nasal “kiiieeeuuu!”, which can be either upslurred or downslurred.
