This beach is getting busy

It’s that time of year again! Right now, on Juno Beach, we have all three species nesting on any given night. Leatherbacks are starting to slow down but loggerheads are going steady and green turtles are starting to pick up.

In addition to all three species taking over Juno Beach, our leatherback nests are starting to hatch! This past week we had our first two leatherback nests hatch. After seeing these big mamas for a few months it’s always amazing to see how small they are when they start. Although some recent studies have begun to shed insight into where little loggerheads and green turtles go once they leave the beach, what young leatherbacks do remains one of the biggest questions in sea turtle biology.

This past week we did have a few ladies make their first appearance on Juno Beach but we’ve primarily seen repeat mamas. Xena and Sally nested on Juno Beach for the first time this season. Sally was originally tagged in 2005 and Xena was originally tagged in 2010.

We also saw three-peat nesters Bimbi and May, as well as second time nesters Scarpetta, Opal, Kelly Clarkson, Lima, and Spica. Of the turtles we’ve seen this past week Spica has been tagged the longest, since 2002. Kelly Clarkson was first tagged this year. Kelly Clarkson was the smallest, measuring 143.3 cm in minimum cured carapace length (CCL) and Lima was the largest at 157.2 cm in minimum CCL.

Generally, when we see a nesting leatherback we notice scarring or injuries. It is very rare that we see a female without any scarring. We often seen females that are missing parts of their flippers. Most of these appear to have been bitten off by sharks. In addition to predatory injuries, some females have notches missing from their carapace, propeller wounds, or extensive scratches on their carapace from boat strikes. Many females have scarring in their shoulder area where they were likely entangled in fishing gear.

It is amazing to see how much these animals endure during their migrations and yet how resilient they are. Animals that are literally missing limbs are still able to survive, migrate, and reproduce. Still, it is so important that we try to minimize our impacts on wildlife like marine turtles. Efforts such as safe and careful boating practices, proper disposal of fishing gear and other trash, and reduction of single-use plastics are all ways that you can help to minimize the impacts that humans have on these magnificent animals.


Our 2018 leatherback nesting season is winding down but make sure to keep following along for the rest of our updates!
