After the complete destruction of a Sterna antillarum (Least Lern) nesting colony on Lovells Island in Boston Harbor in 2007, we set remote-sensing cameras over artificial tern nests in an effort to identify potential nest predators. In addition to Corvus brachyrhynchos (American Crows) and Rattus norvegicus (Brown Rats), Oryctolagus cuniculus (European Rabbits) were photographed burying eggs and destroying artificial nests. These observations indicate that introduced European Rabbits on islands may have a direct impact on nesting terns.
