Enemy Mine

The gull stared into the beady, gold-rimmed eyes of its foe, its own expression one of intense disgust. It dove forward, beak slicing the air with pinpoint precision - but the blow, meant to pierce white feathers, clinked loudly and slid aside at the last moment. The gull stabbed again and again, infuriated by the realization that its target was doing the same, but each time its attacks were repelled by an unseen force. Despite its bravery the gull feared it might never succeed, and was only heartened by the fact that its hated enemy looked just as crestfallen.
