The Sanibel-Captiva Conservation Foundation reported that a lot of excitement has been happening on the beaches of Sanibel and Captiva over the last few weeks, with new sea turtle nests being laid and existing nests hatching every night.

As of July 20, the SCCF was monitoring 757 nests and had conducted inventories on 112 already hatched nests. It reported that the hatching season is off to a great start with about 7,600 hatchlings successfully hatching and emerging from their respective nests. Nest counts are slightly lower than 2021’s nest count of 845 on July 20.

Loggerhead nesting season will begin to wind down in a few weeks, and the nighttime research team is also nearing the end of its surveys, with an official last day of July 31. As of July 20 for the season, the night crew had 204 sea turtle encounters, including 119 unique individuals.

Humphrey Wentletrap is a familiar loggerhead that the SCCF has seen nesting frequently since 2016, which was also its first year conducting nighttime sea turtle surveys. She was documented on three separate occasions by the night crew that year and has been seen nesting every other year since. In 2018, it encountered her twice — one crawl was a nest, and the other was a false crawl (when no eggs are laid). In 2020, she was encountered five times with three documented nests. This year, Humphrey Wentletrap has been observed five times, and all five occasions were documented as nests.

“Since loggerheads lay about three to five nests per season, it’s possible that we saw her for every nest she laid in 2022,” Coastal Wildlife Director and Sea Turtle Program Coordinator Kelly Sloan said, noting that the team measured Humphrey Wentletrap’s carapace (shell) at 3.4 feet long. “None of her nests from this season have hatched yet, but the four nests she laid in 2018 and 2020 produced 553 hatchlings.”

“She has never been reported on a beach other than Sanibel, suggesting strong site fidelity to our island, so we look forward to seeing her again during her next visit, likely in 2024 based on her historical inter-nesting interval,” she added.
