African Skimmer

The African Skimmer is the African representative of the small skimmer family, a group of birds defined by their extraordinary asymmetrical bills. It is a bird of large, undisturbed rivers and lakes rather than ocean coastlines.

Appearance

Adults show black upperparts, white underparts and forehead, and a distinctive bill that is orange-yellow with a black tip, slightly shorter and slimmer than the Black Skimmer's. The legs are short and orange-red.

Key field marks

• Orange-yellow bill with a black tip and elongated lower mandible
• Black upperparts, white underparts and forehead
• Short orange-red legs
• Slim build and pointed wings, with graceful low flight over water while foraging

Similar species

The African Skimmer is the only skimmer species found in mainland Africa, so range alone usually confirms identification; it differs from the Black Skimmer (Americas) and Indian Skimmer (South Asia) primarily by geography and subtle bill coloration.

Habitat and range

African Skimmers are found along large, sandy-banked rivers, lakes, and wetlands across sub-Saharan Africa, from the Sahel south to parts of southern Africa, typically favoring undisturbed stretches of water with exposed sandbars. They are largely sedentary or make local seasonal movements tied to water levels and sandbar availability.

The species depends heavily on stable river systems with exposed sandbanks for breeding, making it sensitive to river regulation, damming, and disturbance.

Behavior

Like other skimmers, African Skimmers feed by flying low over calm water with the lower mandible cutting the surface, snapping the bill shut on contact with small fish. They often forage in the cooler hours of early morning and late afternoon.

Voice

The call is a sharp, tern-like "kip" or "keerp," given in flight, particularly when alarmed near nesting sandbars.

Nesting and breeding

African Skimmers nest colonially on exposed river sandbars and islands, timing breeding to coincide with seasonal low water levels when sandbars are exposed. They lay two to three eggs in a shallow scrape, and nests are vulnerable to sudden flooding as well as disturbance from river traffic and livestock.
