Genetic Parentage and Mate Guarding in the Arctic-Breeding Western Sandpiper
Abstract Extrapair copulations and fertilizations are common among birds, especially in passerines. So far, however, few studies have examined genetic mating systems in socially monogamous shorebirds. Here, we examine parentage in the Western Sandpiper (Calidris mauri). Given that Western Sandpipers...
