Abstract
Male sunfishes build nests and provide care for eggs spawned therein. It is shown here that small non-nesting male pumpkinseed (Lepomis gibbosus) and bluegill (L. macrochirus) will intrude during conspecific spawnings, to fertilize eggs. Such behaviour cuckolds the males which care for the brood.
