FRUIT PICKING GIBRALTAR ATLANTIC GULLS

While on top of the Rock on 20th December 2006 during late afternoon I noticed an increasing number of mainly immature Atlantic Gulls Larus atlantis gibraltariensis soaring over the western slope and hovering above the bushes. It turned out that the gulls were picking olives from the abundant Olea europaea bushes. Gulls are known to eat vegetarian food, Herring Gulls in the Port of Rotterdam f.i. forage on spilt Soya beans while Thayer's Gulls eat spilt grain during spring in Churchill on the Hudson Bay coast. However I never saw gulls actively picking fruit before.

That does not necessarily mean that the phenomenon is unknown: Chuck Carlson, Montana USA, sent me a photo from olive picking gulls.
