Great Gull Island
Great Gull Island is a 17-acre (6.9 ha) island separating Long Island and Block Island sounds, located approximately Lua error in Module:Convert at line 1851: attempt to index local 'en_value' (a nil value). southwest of Little Gull Island. Both islands are located in Suffolk County, New York, and lie roughly midway between Plum Island and Fishers Island.
History
A major stopover for birds following the Atlantic Flyway, Great Gull Island was the home of large colonies of nesting terns up until the end of the 19th century, when many birds were killed as a result of the millinery trade and the construction of military fortifications on the island. In 1897, Fort Michie was constructed on Great Gull Island to guard the entrance to Long Island Sound. The military base was operational from the Spanish–American War until World War II.[1]
Great Gull Island was acquired by the American Museum of Natural History on March 31, 1949.[2] It marked the beginning of the Great Gull Island Project, a long-term effort by staff from the museum and other volunteers to restore the island's ecosystem. Gradually, terns began returning to the island to nest, and the population grew into one of the largest colonies in the world for two species of terns.[3][4]
Terns
The dominant faunal feature of the island during the summer months is the active Common Tern (Sterna hirundo) colony spread across the flatter areas of the island that are not taken over by bittersweet (Celastrus) or common reed (Phragmites australis). A tentative estimation of the S. hirundo mating pairs present on the island places their number at 10,000, though this has not been confirmed, due to the inavailability of a complete and authoritative census.
The other major avian on Great Gull Island is the Roseate Tern (Sterna dougallii), which mostly inhabit the ring of boulders that cover the edges of the island. Originally, these boulders were arranged to prevent erosion and were placed there by the US Army. However, the Roseates are well suited to the narrow crevices and hard-to-reach spaces created in this environment, with their young quite adept at vanishing in between the rocks, only becoming accessible when a parent calls to summon them. The population of S. douglii populating the island is estimated to hover somewhere around 1,000 mating pairs, though no complete census is available.
Personnel
The first and former director of the program was Helen Hays, who had been managing the island since the 1960s. Joe Dicostanzo is responsible for running the database detailing the family history, hatching records, locations of nests and DOB of many of the birds born on or visiting the island.
The Great Gull Island Program has an ongoing partnership with several Argentine projects that monitor the terns during the winter and spring months. Occasionally, as a show of support, an Argentine delegation will arrive to assist in preparation work for "peak week", when hatchings-per-day can range into the thousands. In recognition of their contribution, the west end of the island is thus named "Little Argentina".
