White-throated Robin-Chat
Dessonornis humeralis
A striking medium-sized robin-chat with a slaty gray crown and back separated from the black wings and face mask by a white bar in the shoulder and a white eyebrow, respectively. The throat and breast are white, fading into amber orange on the vent, on the rump, and in the outer tail. Pairs prefer thickets in a variety of woodland types, where they forage secretively on the ground by flicking through leaf litter. They will remain low or sit up on perches to sing their high-pitched melodious song which includes imitations of other species.

Black-and-white Shrike-flycatcher
Bias musicus
Unusual, chunky, short-tailed, crested, yellow-eyed member of the vanga family. Males are strikingly black-and-white, with a small white patch at the front of the wing. Females have a chestnut back, blackish head, and pale underparts. The wings are short and rounded, and the flight is weak. Found in the canopy of humid forest, at low and middle elevations, often along forest edge and clearings. The variable song consists of slurred whistles. Calls include rasps and clearer bulbul-like notes.

Brown-crowned Tchagra
Tchagra australis
A gray-brown bushshrike with rufous wings, a bold pale eyebrow, and a diagnostic brown central crown that is bordered by black stripes. Pairs skulk close to the ground, where they hop and glean for insects in scrub, tangled thickets, and open woodland. The species is more terrestrial than other tchagras. It performs a descending spiral aerial display, making a “prrrrrp” rattle sound with its fluttering wings before singing a rapid descending series of 15–20 musical “chee-ree” notes as the bird returns to the ground. The similar Southern Tchagra differs from the smaller Brown-crowned Tchagra by having a larger, stouter bill and a plain brown central crown lacking black border stripes.

Great Crested Grebe
Podiceps cristatus
Fairly common on lakes, reservoirs, and along larger rivers, mainly with bordering reeds where it builds a floating nest platform. In winter sometimes seen on inshore ocean waters (mainly in freezing weather). Breeding pairs are territorial, but flocks form in winter. Large, elegant, and long-necked grebe. Breeding plumage has beautiful tawny cheeks and black crests (often held flat). In nonbreeding plumage, face and neck bright white with dark line through eye.
