Yellow-billed Cacique
Amblycercus holosericeus
Retiring blackbird of thickets and tangles. Heard much more often than seen, as pairs keep in touch with ‘question and answer calling.’ Creeps methodically in vines and tangles, and most frequently seen as it flies low across a trail or quiet road, usually with one member of the pair following shortly after the other. Note the pale ivory-yellow bill and staring yellow eyes, often striking even with a quick flight view.

Lesser Grass-Finch
Emberizoides ypiranganus
Large finch with a long spiky tail and strong yellow bill. It is yellow-brown above with dark lines running down the back and pale buff below with a gray face and a white throat. Differs from Wedge-tailed Grass-finch in having a white rather than buff throat. Usually found in marshes and humid grasslands. The song is a harsh “ch-ch-ch-ch.”

Bristle-nosed Barbet
Gymnobucco peli
Dark, chunky barbet with a conspicuous buff tuft of feathers on its forehead. Usually found in small groups on and around dead trees in rainforest, secondary growth, and plantations, often alongside Naked-faced or Gray-throated Barbets. The vocalizations include nasal “squeaky toy” calls, a dry rattle, and a series of identical hollow hoots. Very similar to Naked-faced Barbet, but has a large tuft above the bill. Also similar to Gray-throated Barbet, but has a mostly unfeathered head and a pale bill.

Orange River Francolin
Scleroptila gutturalis
Medium-sized, beautifully-patterned francolin. Shows rufous patches in the wings in flight. Found on the ground in areas with thick grass, including pure grassland and open savanna. Shy and retiring. Loud call is a quickly repeated “chuk-a-cheiw”. Similar to several other francolin species, which also show rufous in the wing. Lacks the belly barring of Shelley’s Francolin, has a black necklace unlike Red-winged Francolin, and found at lower elevations than the mountain-dwelling Moorland Francolin.
