Breeding Range Update for Three Seabird Species in Labrador

Recent data (1998–2003) collected during field surveys for nesting Common Eider (Somateria mollissima L.) along the Labrador coast have confirmed nesting by Black-headed Gulls (Larus ridibundus L.) and Double-crested Cormorants (Phalacrocorax auritus Lesson), and suggest possible nesting by Caspian Terns (Sterna caspia Pallas). It appears that both Double-crested Cormorants and Caspian Terns have previously nested in Labrador, whereas nesting by the Black-headed Gull represents a recent range extension.
