Description
Phillip Gienapp and Juha Merilä tested in 2010 whether Siberian jays are as faithful as their reputation claims. Extra-pair paternity, chicks fathered outside the pair, is common in birds and varies with ecology and social life. Group-living species often show high rates, which made the group-living jays an interesting case.
Genetic testing found no evidence of extra-pair paternity in the Siberian jays studied. A species that truly keeps pair bonds, with fathers investing in their own young, is a valuable exception for testing theories about why cheating evolves elsewhere. The jays' fidelity also fits their cooperative family life, where trust inside the group is the working currency.
