Abstract: In captive black-headed gulls (Larus ridibundus L.), immature birds often win encounters with adults. Under natural conditions, immatures win more fights as challenger, but lose more as challengee if no food is involved. Immatures win more fights for food, both as challenger and as challengee. From the results presented here, and after reviewing the literature on aggressive interactions in the black-headed gull, it is concluded that immatures start and win more fights than adults. They are also more daring in interactions with other species. Some of these differences are probably a result of different foraging strategies of immatures and adults. However, fighting itself may have a higher value for immatures than for adults, perhaps as part of a learning strategy.
