Abstract
    On 19th January 1975, at New Brighton, Merseyside, the author watched an adult Iceland gull Larus glaucoides persistently stealing food from oystercatchers Haematopus ostralegus. As soon as one of the waders had food in its bill, it was attacked by the gull and forced to drop the food, which the gull then consumed. The method of attack was a simple, straight dive at the oystercatcher, which offered no resistance. The process was repeated at least ten times during the hour-long observation.
