Yellow-crowned Elaenia

Medium-sized, long-tailed, long-billed warbler. The back is olive-green and the underparts yellow. Found in montane habitats including bamboo, moist scrub, and forest edge. An active and energetic bird of the undergrowth. The distinctive song is an exuberant mix of downslurred and upslurred whistles and low rattles. Similar to African Yellow-Warbler, but in the areas where they overlap, mostly found at higher elevations, and distinguished by the olive-green, not black cap.

This huge, macabre-looking stork has a massive dagger-like bill and naked pink head and neck that appear severely sunburned. A white ruff and loose inflatable skin on the neck add to its odd appearance. It soars effortlessly at great heights searching for food; note its white belly in flight. Marabous are equally content in wetlands or in dry bush; they are most frequently encountered lurking near carrion, as they attend kills of major predators and will opportunistically snatch scraps. They also readily scavenge around humans and waste dumps.

A nest parasite that lays its eggs in the nests of Rock Firefinches. Breeding males are black with green iridescence and a pale brownish panel in the wings. Females and non-breeding males are streaky and brown on the back and pale below, with a bold facial pattern. The bill is whitish and the legs pale purple. A scarce, local, and poorly known species. Found in rocky areas within savanna. Given current knowledge, can only be confidently identified by vocalizations. Imitates the vocalizations of its host, Rock Firefinch, including soft “teew” whistles, a descending trill, “tep” notes, and “pit-pit-pit” calls. These are often mixed into a scratchy jumble of high-pitched notes.
