| Résumé : | The frequency of extra-pair paternity was studied in a population of Coal Tits Parus ater using DNA fingerprinting technique. High values were obtained: 15 of the 20 broods investigated (75%) contained at least one nestling sired by an extra-pair male and overall 40 of 158 nestlings (25.3%) were extra-pair young. Inter- and intraspecific comparisons revealed that breeding density cannot explain this high frequency of extra-pair paternity in Coal Tits. |
