An aircraft lighting system includes a light source and a processing system. The light source is rotationally mounted on an external surface of an aircraft to rotate at least 360-degrees about a rotational axis. The light source is configured, upon being electrically energized, to emit light. The processing system is in operable communication with the light source and is coupled to receive an anti-bird mode activation signal and one or more sensor signals representative of a position and flight path of birds. The processing system is configured, upon receipt of the anti-bird mode activation signal, to process the one or more sensor signals to determine the position and flight path of the birds, electrically energize the light source to emit light, and command the light source to rotate in one or more directions so that the emitted light is directed toward birds.
