Molecular evidence for extra-pair paternity and intraspecific blood parasitism in the black-headed gull
Social monogamy is common among birds, while gen etic monogamy is supposed to be rare. I investigated th e genetic mating system of the Black-headed Gull Larus ridibundus, where, as in seabirds and most other long-lived and socially monogamous birds, extra-pair paternity (EPP) is typically rather in...
