Résumé :	During the breeding season of 1998, small mammals were found on four occasions in the menu of the Black-headed Gull. A dead, but intact Mole and Common/French Shrew were found in two empty nests of the Black-headed Gull. A three weeks old gull chick regurgitated a Wood Mouse, and finally, it was observed how a Black-headed Gull tried to feed a mouse to its youngest offspring. The chick was unable to eat the mouse since it was too big. These observations and an earlier one in 1997 suggest that small mammals may occur more often in the diet of coastal Black-headed Gulls than hitherto assumed.
