Breeding Arctic Terns Kill Lemmings

Arctic terns (Sterna paradisaea) are well known for exhibiting vigorous defense of nests at their breeding colonies. However, in 2008 we observed a previously unreported behavior by terns. We watched chick-rearing adult terns attacking collared lemmings (Dicrostonyx groenlandicus), which included re...
