Rufous-sided Broadbill
Smithornis rufolateralis
A small broadbill of lowland wet forests, often found near water in thick vines and tangles. Note the compact shape, the white throat, the rufous chest, the thin black streaking on the underparts, and the white spangling on the wings. Males have dark heads and backs. Like other African broadbills, has a white patch on the back that can be concealed by other feathers. Overlaps locally with both African Broadbill and Gray-headed Broadbill, but note Rufous-sided Broadbill’s habitat, the rufous on its chest, and the white spots on the wings. Most often located by its display sound, a decidedly frog-like trilling “brrrt” that lasts up to half a second, rising in pitch.

Southern Banded Snake-Eagle
Circaetus fasciolatus
Chunky dark brown raptor with barred underparts. Found in and adjacent to forest, thick woodland, and exotic tree plantations, often near water. Sits for long periods and doesn’t often soar. Generally scarce and uncommon across its range. Call is a weird, strangled “whaaat ho-ho-ho-haaa”. Very similar to Banded Snake-Eagle, but no overlap in range. Somewhat similar to African Cuckoo-Hawk, but larger and chunkier, with a dark brown rather than gray head.
Canvasback
Aythya valisineria
Attractive duck with distinctive triangular head; forehead slopes seamlessly into the long bill. Males are white-bodied with black chest, reddish-brown head, and red eye. Females are dull grayish-brown with unique head profile and dark brown eye. Breeds in lakes and marshes. Winters in any large body of water with submerged aquatic vegetation on which to feed. Dives frequently, searching for vegetation and invertebrates. Often gathers in large flocks in nonbreeding season.
Sooty Gull
Ichthyaetus hemprichii
Medium-sized elongated gull. Brown-gray overall with a long bill and dark underwings. Similar to White-eyed Gull, but with dark underwings. Slightly larger and heavier with browner adult plumage than White-eyed Gull. The bill on Sooty Gull is also thicker and clearly two-toned in all ages compared to White-eyed Gull. Coastal, breeds on islands and coral reefs.
