Breeding Status, Habitat Use, and Management of Threatened and Endangered Wildlife in New Hampshire's Coastal Region

摘要

Historically, Lunging Island at the Isles of Shoals supported New Hampshire's most significant documented tern colony, which peaked at 1500-2000 Common Tern pairs between 1928 and 1938, and also included 50-60 pairs of Roseate Terns ('Sterna dougallii') and 25-30 pairs of Arctic Terns ('Sterna paradisaea'). This colony's decline during the 1940's followed a decrease in human activity on the island and subsequent increases in Herring Gull ('Larus argentatus') AND Great Black-backed Gull ('Larus marinus') numbers. Terns abandoned Lunging Island by 1955. The goals of this project were to maintain the on-going data base on colony size, breeding status, and reasons for failure at existing colonies; continue to experiment with floatable nest platforms to mitigate tidal flooding; and identify important foraging areas.
