Satellite transmitters now on three loggerheads

By Staff | Jul 22, 2020


The Sanibel-Captiva Conservation Foundation’s turtle team is seeking to learn more about nesting loggerhead sea turtles.

“We are excited to share that we have placed a third satellite transmitter on a loggerhead sea turtle this season,” Research Associate Andrew Glinsky said today. “This turtle is named Periwinkle and she had been previously encountered on Sanibel in 2016 and 2018.”

Since Periwinkle was nesting during the 2018 red tide bloom, the data will also contribute to a research project investigating the long-term impacts of red tide events on the health and reproductive success of nesting sea turtles. The project is being funded by the Florida RESTORE Act Centers of Excellence. Additionally, tracking Periwinkle will help the SCCF learn more about the post-nesting movements, migratory pathways and foraging grounds of loggerheads that nest on the Gulf coast of Florida.

“So far, over the course of six days, Periwinkle has maintained a southern trajectory and traveled over 100 miles towards the Florida Keys,” biologist Jack Brzoza. “We are excited to see where she will go and look forward to tracking her.”

Earlier in the season, SCCF’s sea turtle team placed satellite transmitters on two other loggerheads, Junonia and Pepper; the AWC Family Foundation funded the satellite tagging. Also, in collaboration with Florida Leatherbacks, the SCCF is satellite tracking a rare leatherback named Juniper that nested on the islands’ beaches for the first time this season.
