Wolff, University of Newcastle, School of Biology, Ridley Building, Newcastle NE1 7RU, UnitedKingdom.Extra-pair paternity is common in many socially monogamous bird species. Increasing evidence suggests that extra-paircopulations are female-driven, but benefits for females mating outside social pair-bonds are still poorly understood. Themost influential explanation, ‘‘good genes’’ hypothesis, states that females mated socially with low quality males, engagein extra-pair copulations to obtain genetic benefits for their progeny. According to this model, enhanced performance ofextra-pair offspring is expected. Here, based on 4-year study of collared flycatcher Ficedula albicollis, we compared thecondition of extra-pair and within-pair young. We found no difference in immune response and body size betweenmaternal half-siblings raised in the same nests. Additionally sex ratio was not biased among extra-pair nestlings, andpaternity was not associated with hatching rank. Our results failed to reveal ‘‘good genes’’ effects in the studiedpopulation. These effects might be hard to detect, but other hypotheses should also be studied more thoroughly in thefuture. |
