Nesting Leatherback Sea Turtles

We had the opportunity to go on our own beach walks to look for nesting leatherback turtles. I've never seen leatherbacks, and I've always wanted to since the moment i started getting interested in sea turtles. They're massive. They dive deeper than the whales in search of food. They head into the oceans as babies and go where??????? They're fascinating and I think just pure magic.

So when I heard that there were good numbers of leatherbacks beginning to nest on the beach down south, I happily gave up a turkey weekend to go down to wander the beaches at night looking for one of these big creatures. Hoping that I could get even a glimpse of my first leatherback.
The weather was spitting rain sometimes and BLOWING wind all the time. You'd not think you'd get chilly on an almost summer time night out at the beach in south florida but I sure did get cold the first night.

As luck would have it, our first night down there, we found one leatherback. We were able to sit and watch her for about 30 minutes before she headed back into the water. She was MASSIVE!!! Her shell was as long as I am tall. Her head was as large as a soccerball at least. When we found her, she was in the process of covering her nest. You could stand 20 feet away from her and feel the impact of her big flippers hitting the sand as she brought them down just before flinging sand back behind her. By the time she was back in the water, it was beginning to rain some more and we decided we'd rather not search the beach in the rain. The next morning we went out to see if we could get pictures of the tracks of her coming up the beach.

This is how big a leatherback nest is.

The second night we went out the weather had at least quit spitting rain, but LOOOORDY the wind was really kickin it up.

One of our first stops yielded the first Leatherback of the evening. And she'd just gotten there. Her name is Jupiter and her shell is longer than I am tall (I'm 5'5") and she's been nesting on that beach since at least 2002. We got to watch as she dug her nest, her back flippers working as gently and dexterously as if we were using our hands to pull sand out. She'd alternate one scoop of sand with her left flipper then one with her right, and so on and so on until she could no longer reach sand with her back flippers. At that point, she started laying. AMAZING. with each push two or three, sometimes four eggs would come out. Once she was done laying she ever so gently began covering her eggs, using her back flippers to make a rounded top, packing the sand tightly, until eventually she began using her front flippers to cover everything up. When she's decided that she is done, she lumbers back to the ocean, to disappear beneath the waves. From start to finish it takes about an hour and a half or so for her to lay her eggs.

With the gorgeous night and excitement of seeing her actually lay, we decided that we'd continue looking for more turtles...so we continued north up the beach. We got to the very north part of the beach and using our night scope look down the beach and we actually see a leatherback coming out of the water, up the beach! As we head down that way, we encounter a set of tracks. A turtle had already come up the beach. Not wanting to scare that leatherback that was coming up the beach we followed those tracks up to a nesting Loggerhead! A bonus turtle for the weekend since they don't typically start nesting til May.

We watched her until she went back into the water, she was in the process of covering up her nest but even that took about 30 minutes. Afterwards we headed up to where the other Leatherback was and got there in time to see her dropping her eggs into her nest. This lady was quite a bit smaller, more streamlined looking, than the other two. Her shell was probably 5 inches shorter than me....so that would put her shell at about 5 foot long. We got to watch her, until she eventually decided to go back into the ocean. She however, took probably close to two -two and a half hours to finish her nesting.

For whatever reasons, Leatherbacks prefer to nest on coarse sandy beaches, often that are hit with a good deal of erosion. Here's a nest that makes one wonder how high the slope was when the lady came out to nest. Clearly a good deal of the sand has washed away, though the nest had not done so.

And there was a turtle that came up in the night, looking to nest somewhere and hit the cliff of sand and just could not get over it. so she followed the cliff until she decided to pick a spot to nest. It looks like a tractor went through there...

I look forward to going back down to hopefully see some babies hatch and see more turtles coming out of the water ....

Dani, loved the story and the pics. That had to be a life time type experience that you had. Lucky You! Thanks for posting. I enjoyed it all so much. Hopefully the baby turtles will hatch out at night and have a better chance of getting back to the ocean.

great experience Dani, thanks for sharing it. I was able to experience much the same thing on a small island off of the Dry Tortauga. They are so smooth in the water.

Just got back from Florida near Stuart. We went fishing offshore a few days in a row and saw many, many turtles. I guess they were getting ready to start making their way to start nesting. Had no idea their nests were that huge, thanks for the pics.
 
WOW! That is awesome! I never knew Loggerheads nested in Florida. I untangled one once in the 80's offshore of R.I. when I was lobstering. It had the buoyline around his neck. It was very docile until I let him go. It was pretty spooky reaching around his HUGE head. Not like a snapping turtle luckily
Thanks for the cool story!

Thanks guys....it was quite an amazing weekend. Honestly I'm not sure which is more fun, amazing or what not....helping to release the little babies and send them off to the sea (though i've never seen or held a baby leatherback....I've seen and held the baby loggerheads and greens....I'm hoping this year I'll get to see baby leatherbacks), or watch as a close to one ton creature labors out of her watery world and becomes for a moment, a land animal, the closest thing to a dinosaur there is, digging and laying eggs in the sand, only to return back to the watery world and disappear until who knows when.

Brian, I'm heading offshore this weekend in the Gulf so "perhaps" I'll be lucky enough to get some pictures of turtles out there. The turtles tend to hang out near the beaches when they're between nestings. Most turtles will nest several times a season, some of the leatherbacks as many as nine times in one season, with about ten days between each laying. How'd you do fishing?

Wiz, I was amazed at how smooth those ladies were. I felt their shells and flippers and I was totally unprepared for how smooth they were. So different from Loggerheads that I see that are covered in barnacles...these ladies were very clean of "hitchhikers".

There is one turtle who has the tendency to nest in the early morning hours and extend past dawn, so perhaps i'll be able to make a trip down to get some pictures of her on the beach to add to this post...

William, last season its estimated that there were 1 million turtle eggs laid on the 13 miles of beaches monitored by the Loggerhead Foundation....the majority of those were Loggerheads....double that to the North on the Archie Carr Refuge and then maybe another half million in the rest of Florida....again most of those Loggerheads....we do get a good deal of Loggerheads....and a bucket full of them are PURE CUTENESS....and it's nice to hear that you stopped to help a turtle out...some good juju if you ask me...

Dani - Very interesting and informative. Is that last nest marked n the beach ? What keeps predators from digging them up for the eggs ?
I gotta see one of these big turtles so I am headed over to google.
thanks -

all the nests that are found while the turtles are laying are marked with a golf ball with a receiver inside so that using a machine of some sort they can find exactly where the nest is the next morning. There are turtles, like the one that left the tracks in the picture, that go up and nest without anyones knowledge so they don't know EXACTLY where the nest is. The golf ball is placed as the turtle is burying the nest and their little remoctes can sense it so theat the next day someone can put up a stake where the nest is exactly. There were very few down south in Juno that were cordoned off with tape like in the picture. Mostly it's just a stake with a sign. But that is done the next morning.

Up here in Jax, they are ALL surrounded by orange chicken wire to keep people, and to some degree predators out of the nest.

As far as I'm aware, there's nothing to keep predators away from the nest. Though the night we saw our first layng, there was a skunk that was sniffing around, hoping to get close enough so that it could get to the eggs, but with the people there, it wouldn't come over to get eggs. The next morning it was not dug up, so "perhaps" people being there helped? There are raccoons as well, but they don't seem to be a big issue. The biggest predator is dogs, though at least on that beach they seem to be very well controlled.

The "idea" I guess for turtles is to overwhelm the predators with pure volume of hatchlings so that "some" of them could make it. If a Leatherback lays about 100 eggs per nests and nests 4-7 times a season, that is 400-700 babies per season per turtle....so "some" would make it through all the predators. It really sucks to be a baby turtle....I think quite possibly worse than a mullet. But perhaps not.

Light pollution is a big issue for hatchlings, but Juno has been "pretty good" about darkening their lights during the turtle season. It "costs" to have a light that is too bright these days.

There are plenty of "issues" for hatchlings....predators aren't as "bad" these days in FL b/c of "civilization" but then civilization does present its own problems

Hi Dani - Thanks for that. When I went on google and found images, I could not believe how big some of these turtles get.........massive........ and the other thing I saw were shots of hatchlings on their way to the water...........many, many at a time. I think you were smart not to try to take pics with a flash but it must have been tempting. Thanks again for a super post !
