AFRICAN BLACK DUCK
While most waterfowl prefer the stagnant waters of large lakes and open wetlands, the African Black Duck (Anas sparsa) is a true specialist of the high-altitude mountains. This incredibly shy and secretive bird is a permanent resident of the fast-flowing, rocky streams and rivers that cascade down the slopes of the Rwenzori Mountains. Spotting one of these elusive ducks expertly navigating the white-water rapids of the Mubuku or Nyamwamba rivers is a rare and highly rewarding experience for birdwatchers trekking the lower montane zones.
Visually, they are striking yet perfectly camouflaged for their shadowed, rocky environment. Their plumage is predominantly a deep, sooty blackish-brown, heavily speckled with conspicuous white spots across their backs. They possess bright yellow to orange legs and a distinctive metallic blue-green patch on their wings, known as a speculum, which is bordered by bright white stripes. Unlike many duck species where the males are vibrantly colored to attract mates, both the male and female African Black Duck look nearly identical, though the male is generally slightly larger.
Their habitat in the Rwenzoris is fiercely defended. They are highly territorial year-round, with a single monogamous pair often claiming a considerable stretch of river as their exclusive domain. They are rarely seen in large flocks. Instead, they spend their days quietly foraging along the wooded banks of shallow riverbeds. As omnivores, their diet consists of aquatic plants, wild berries, insects, crustaceans, and small fish eggs, which they filter from the rushing mountain water.
For trekkers on the Central Circuit or Kilembe trails, the best time to spot them is during the early dawn or late dusk when they are most active. You will rarely find them on the high-altitude crater lakes like Lake Bujuku or Kitandara, as they strictly prefer the heavily oxygenated, moving waters of the lower rivers that drain into Lake George and Lake Edward. If startled by hikers, they are known to rarely take flight. Instead, they will instinctively dive underwater or swim rapidly downstream, using the dense overhanging vegetation and river boulders to disappear completely from sight.
