High fidelity--no evidence for extra-pair paternity in Siberian jays (Perisoreus infaustus).

Extra-pair paternity (EPP) in birds is related to a number of ecological and social factors. For example, it has been found to be positively related with breeding density, negatively with the amount of paternal care and especially high rates have been observed in group-living species. Siberian jays...
