Senegal Eremomela

A nest parasite that lays its eggs in the nests of Purple Grenadiers. As with other whydahs, breeding males are spectacular, whereas non-breeding males and females are drab. Breeding males are mostly black, with golden-buff coloring on the cap, the belly, and the elongated central tail feathers. Non-breeding males and females have a brownish back, a golden-buff head, and a red bill. Found in rather dry savanna and cultivated areas. Non-breeding male and female can be identified by their red bill and their almost unmarked plain buff head. Not very vocal, but does imitate Purple Grenadier, and gives a quick jumble of high-pitched whistled notes. 

One of several medium-sized, kiskadee-like flycatchers that are bright yellow below, with bold black-and-white head pattern. Rusty-margined is one of the smaller ones, with a smaller bill than Great Kiskadee. Most similar to Social and White-ringed Flycatchers; look for combination of black cheek (not gray) and especially obvious rufous in the wings. Shorter bill than White-ringed. Voice is helpful: listen for lazy-sounding, slightly burry “wheeer” call. Found in a variety of open wooded habitats such as forest edge and second growth, often around water.

A small, fork-tailed, sooty-brown swallow with different plumages for the sexes: distinctive male has a pure white head and narrow black eye stripe; female has a mostly ashy head with white throat. Immature lacks white on the head. Pairs use clearings and edges of evergreen forest, open woodland, and cultivation. Resident in East Africa, but an intra-African breeding migrant in Zambia and Malawi between October and May. Superficially more similar to swifts than other swallows. Note the differences in flight style: flightier with deep wing beats and rapid changes of direction, as opposed to the more stiff-winged flight of swifts.
