AbstractHerring gulls Larus argentatus were observed to kleptoparasitize American black ducks Anas rubripes feeding on fiddler crabs Uca pugnax in coastal New Jersey. Although widespread in Laridae, kleptoparasitism has never been described between these two species. Over two winters of intensive 24-hour behavioral observations, this interaction was observed on two occasions during similar tidal conditions. Although this appears to be a rare interaction with limited energetic consequences, we note that quantifying these uncommon interspecific interactions is a benefit of thorough behavior observations, which may refine estimates of daily energy expenditure.
SponsorThe companion study under which this work occurred was funded by the Black Duck Joint Venture, New Jersey Division of Fish and Wildlife, Edwin B. Forsythe NWR, Cape May NWR, and the University of Delaware. We thank Patrick Devers of the U.S. Fish and Wildlife Service for encouraging this note and two reviewers for providing editorial advice.
