The Bermuda Turtle Project is pleased to announce that three turtles, originally tagged in Bermuda in the 1990s, have been seen on nesting beaches in Costa Rica and Mexico, each bearing titanium tags that were put on them during turtle tagging sessions by the Bermuda Turtle Project.

“These results demonstrate the linkage between young green turtles that grow up in Bermuda waters and Caribbean nesting beaches that are thousands of kilometers away,” explained Dr. Anne Meylan, who, along with husband Dr. Peter Meylan, serve as the project’s scientific directors. “They also show the long period of time it takes for green turtles to reach sexual maturity, some 30 years or more!”

Research into Bermuda’s green turtles began in 1968 by Dr. H.C. Frick, a trustee  of the Caribbean Conservation Corporation, and continues to this day under the Bermuda Turtle Project, which is a joint effort between the Sea Turtle Conservatory, the Atlantic Conservation Partnership, the Bermuda Zoological Society and the Bermuda Aquarium, Museum and Zoo. Through the years, more than 3,500 turtles have been captured, tagged, and released, providing data on the island’s juvenile green sea turtle population. Turtles tagged in Bermuda have also been recovered in Nicaragua, Panama, Cuba, Dominican Republic, Grenada, St. Lucia, and the US.

According to Dr. Meylan: “Few projects have recorded migrations between the habitats that green turtles inhabit when they are immature, and their nesting beaches. Recaptures of this kind present a rare opportunity to test whether theoretical estimates of age-to-maturity are correct. The data are only possible because of the long-term tagging effort in Bermuda and careful beach monitoring at the nesting sites.”

“We have thought for many years that Bermuda serves as an important steward for Caribbean green turtles, providing a safe and healthy environment in which they can mature. These recent recaptures are direct evidence of the link between developmental habitat in Bermuda and nesting beaches in the Caribbean.” 

“The BTP brings students from the Caribbean to Bermuda every year for a course in sea turtle biology and conservation. These three recapture records confirm the relevance of Bermuda to sea turtle conservation in their native countries, including Mexico and Costa Rica, where the recaptures were made.”

Bermuda Turtle Project Coordinator, Jennifer Gray, said: “It takes years of standardized research and an enormous effort by many people to acquire this kind of outstanding and exciting information. Bermuda can and should be very proud of our renowned conservation of this endangered species and a research initiative that is known and applauded by sea turtle scientists around the globe.”
