First observation of African tigerfish <i>Hydrocynus vittatus</i> predating on barn swallows <i>Hirundo rustica</i> in flight

Abstract

A population of African tigerfish Hydrocynus vittatus from the Schroda Dam, actively prey on barn swallows Hirundo rustica in flight. This behaviour was discovered during a radio telemetry study and documented using a motion picture video camera. These results show that an avivorous diet is a part of the feeding biology of H. vittatus, and may occur in other populations.
