Introduction. Monogamy is thought to be the usual mating system in dabbling ducks and documented cases of bigamy are very rare for any Anas species (Lebret 1961). The following observations on wild-caught Cape Teal Anas capensis, breeding in flight pens, show that bigamy is possible in this species and suggest that it may be expected to occur in wild birds.
Keywords. Cape Teal, Anas capensis, dabbling ducks
