Green Warbler

A fairly small bustard of thick brush in dry country. The male has a buff crest that is usually hidden, and both sexes have a black belly. Found in dry savanna and thornscrub habitat with lots of bushes, unlike most bustards, which prefer grass-dominated habitats. Similar to Black-bellied and Hartlaub’s Bustards, but smaller, and prefers different habitats. Larger than Little Brown Bustard, with a black belly. The call is a rising and accelerating series of distressed-sounding notes that often precede the display: a quick flight up, then a plummet to the ground.

A nondescript-looking small songbird of arid open areas. Adult brownish above, white below; juvenile similar but has neat white edging to its dark feathers. Crestless, stout-billed appearance distinguishes this species from other larks in the region. The slightly larger Greater Short-toed Lark is similar but has a small black neck stripe, weaker breast streaking, and is paler overall, with a lighter face and belly.

This small duck has a solidly chocolate-brown ‘skull cap’, white cheeks, and a distinctive pink-red bill with a dark saddle. In flight, the buff flight feathers with a black stripe are distinctive on otherwise all-brown wings. It prefers foraging on open fresh water, with seeds and plant matter forming the majority of its diet. The similar Blue-billed Teal differs from Red-billed Duck by being smaller and having a silvery-blue bill and dark smudges on the cheeks. Cape Teal and Bernier’s Teal (the latter endemic to Madagascar) both lack the strongly contrasting face pattern of Red-billed Duck.
