Earlier this month, Sea Turtle Conservancy (STC) was contacted by turtle colleagues in Mexico who had spotted a green turtle with a satellite transmitter on her back nesting in Quintana Roo, Mexico. It was our Esperanza from Cuba! After receiving photos from Mexico, STC was able to identify Esperanza by her flipper tag number (which is unique to only her) and her satellite transmitter.

This discovery is very important because it helps confirm a pattern our partners with the Cuban Marine Turtle Conservation Program have been observing recently based on flipper tags and genetics. It was the same area where they had seen several previous nesters from Cuba go.
But wait…
What are sea turtles that nested in CUBA doing nesting in MEXICO?? This is very unusual, and it suggests that sea turtles may not be as loyal to one beach as we thought! Most females return faithfully to the same beach each time they are ready to nest. Not only do they appear on the same beach, they often emerge within a few hundred yards of where they last nested!
One of the benefits of using satellite transmitters to track sea turtles is that it helps us determine turtles’ nesting site fidelity. Or in this case, lack of fidelity.
We will continue to watch Esperanza closely over these next few months and so can you! As part of the Tour de Turtles program, you can visit Esperanza’s tracking map to see where she travels next! /trackingmap.php?id=144
Esperanza is a beautiful adult green sea turtle who was released with a satellite transmitter after nesting in Guanahacabibes Natural Park, Cuba on June 29, 2016. This turtle mama laid 152 eggs! She measured 107 cm in curved carapace (shell) length and 93 cm in curved carapace width. Esperanza, which means “hope in Spanish,” was named by her sponsors at SEA LIFE Trust and is participating in the 2016 Tour de Turtles migration marathon.
