Rynchops flavirostris
The African Skimmer, *Rynchops flavirostris*, is an elegant and uniquely adapted waterbird, instantly recognizable by its distinctive bill structure. Measuring 36-40 cm in length with a wingspan of 106-116 cm, adults sport a sleek black plumage dorsally, contrasting sharply with their pristine white underparts. Its most striking feature is the bright orange-red bill with a yellow tip, where the lower mandible is conspicuously longer than the upper, a specialized adaptation for its unique fora...
Found exclusively in freshwater and brackish aquatic environments, African Skimmers prefer large, slow-moving rivers, lakes, lagoons, and estuaries, particularly those with extensive sandbanks or mudflats for nesting and roosting. They primarily inhabit lowland areas, avoiding heavily forested or...
Their diet consists almost exclusively of small fish, particularly cichlids and minnows, supplemented by aquatic invertebrates, which they catch by skimming the water's surface with their unique bill.

Their foraging strategy is iconic: flying low over calm waters, they dip their elongated lower mandible just beneath the surface, snapp...
The African Skimmer has a wide but fragmented distribution across sub-Saharan Africa, typically avoiding the arid interior and dense rainforests. Its breeding range spans from Senegal and Gambia in the west, eastward through the Sahel countries, to Ethiopia and Somalia, and southwards through Eas...
