A plain-Jane BG here, but the pose the gull gave me here was pretty cool I thought. It was flying past in a straight enough line but suddenly manoeuvred in this way to start a sudden dive to chase a fellow gull that had just grabbed a river mussel. The two subsequent frames before letting go the shutter button featured nothing but beautiful blue sky.
