Résumé :	The maintenance of an effective immune system may entail physiological costs only affordable by individuals in good condition. Some species, like Black-legged Kittiwakes (Rissa tridactyla) in the high arctic, experience important physiological changes during breeding in order to fulfil their reproductive goals. We studied the effects of breeding effort on the cell-mediated immunity (CMI) of adult breeding Kittiwakes. Parent Kittiwakes showed a significant decrease in CMI from hatching to
