When will a nest hatch? By far it’s the question we’re asked the most, and no matter how many times we get it our answer is still the same: we don’t know. We’re not being maliciously obtuse, it’s the truth. We don’t know when these turtle babies will be “born” any better than you know exactly the date and time of your granddaughter’s birth. They come out whenever they’re ready.
How long do the eggs stay in the sand? The average incubation period is sixty days, but that’s only an average. Air and sand temperature can affect the actual incubation period with hotter sand sometimes speeding up the process. And we’ve had a darn hot summer, so some of our nests might go a bit earlier. As we move into the cooler fall temperatures (we hope they’re cooler, anyway) their time in the sand will probably be closer to the average.
Is there any way to guess when a nest is ready? Sort of. Obviously, the first thing to look at is when the nest was laid and when those sixty days might be getting close. And this year we have a new tool, a hydrophone that we use to monitor the sounds happening down in the sand as the date gets closer. Once the hatchlings break out of their shell, using a special adaptation referred to as their “egg tooth” (technical name caruncle) they start jostling their neighbors out of their slumber. Pretty soon everybody is up and kicking. All of that activity underneath causes the sand on the surface to begin to sink.
If it looks like a nest may hatch what else can I look for? Turtle Project volunteers will create a ramp, a smoothed area with sand “guardrails” that will hopefully guide the little critters safely in the direction of the surf. Hatchlings are so tiny that even a small footprint in the sand can trap them or delay their trip. And since they’ve been living in the dark for months any bright light can disorient them, sending them quickly off-course. They head toward the brightest object around which ideally is the moon and its reflection on the water and waves. A sure sign that a nest is close, at least according to our decades of experience, is the sight of our “nest sitters” huddled around a nest from dusk until the wee hours of the morning – hoping.
What happens during a hatch? It’s a group effort, a real family affair, at least for the turtles. They work together to battle through the broken shells and the constant flipper-in-the-face to make their way toward the surface. It’s dig and rest, dig and rest. As they near the top the group comes to a stop and waits just below the surface. Millions of years of existence as a species have told them that predatory attack is less likely at night, so they’re waiting for the sun to set and the sand temperature at the surface to cool down. At that point, they emerge in mass in what we call a “boil.” If all goes well, they locate the horizon and make a mad dash for the surf.
Why are the Turtle Project volunteers there? From the 1970’s Karen Beasley and her mother, Jean, recognized the increasing stressors of coastal development and the natural affinity we all have for the sea, and the impact on sea turtles. Our volunteers are there to minimize any adverse effects we humans may have on this critical step in the continuation of the species. These are federally protected and critically endangered animals, and when our “nest sitters” are on-the-job they are the final word on protocol. They are there for crowd control and for education and there are specific rules to follow if you are fortunate enough to see a nest hatch.
Sit quietly, away from the nest and ramp area. It may or may not boil, and if it does it may be hours before you see the first flipper. If you become impatient, please step away.
Do not use flash photography or use your phone as a “flashlight.” And do not bring flashlights to the nest. Ideally you should turn your phone off and pay attention to the miracle you’re about to see.
Keep children and yourself away from the nesting area. Do not wander near or in front of the ramp. Do not bring your pets with you.
Do not chase after or touch the hatchlings. Our volunteers are on-hand to redirect any hatchlings who stray off course.
You may ask any questions of our volunteers but please do so respectfully. They operate under federal regulations and what they say goes. This is not a venue for a political or philosophical debate.
I missed the hatch – am I out of luck? Not necessarily. If you’re going to be around for a while you can come to the nest analysis which is done during daylight hours, three days after the hatch. Volunteers will carefully excavate the nest and document their findings. And the “findings” will often include a few late risers who didn’t hear the alarm go off. Data collected will include the total number of eggs (including unhatched,) the number of live hatches and any other things of note. If you missed the boil this is the next best thing and worth your time. Our volunteers are a bit more relaxed you can still ask them any questions you may have.
What do I do if I find a hatchling on the beach? Carefully pick it up and put it in a small container with some sand and a very small amount of water - barely cover the flippers. With this extreme heat, it’s important that the little critter does not bake in the sun for hours. Then call our Director of Beach Operations, Terry Meyer at 910-470-2880. Calls to her number after hours will automatically be forwarded to her. You may also call the hospital during operating hours: 910-329-0222. We will take the information and one of our area coordinators will meet you to retrieve the hatchling and refer it to us for follow-up.
Anything else? Some obvious things: turn off any bright outdoor lights that would send hatchlings in the wrong direction; pick up all beach paraphernalia (chairs, toys, towels) and take it with you when you leave and fill in any holes you dig. Please do not call the hospital to ask about any specific nest – we don’t have any data in front of us and are unable to answer that question. Even with all the coverage by our Topsail Turtle Project volunteers it’s possible to miss nesting or hatching signs for a variety of reasons. That’s why we ask you to be our extra eyes and to report any turtle activity to our Director of Beach Operations, Terry Meyer at 910-470-2880. And we continue to admit many turtles with various injuries or illnesses. Please be on the lookout for any turtle in distress, injured (or dead), and call Terry or our hospital for a quick response. The State of NC hotline for stranded, sick, and injured turtles at 252-241-7367. The state number picks up 24/7. Remember that interfering with or harassing federally protected sea turtles in any way makes you subject to steep fines and possible imprisonment. Our work with sea turtles, at the hospital and on the beach, is authorized by the NC Wildlife Resources Commission, ES Permit 23ST05.
We’re open Monday through Friday in August with tour hours posted on our website: www.seaturtlehospital.org. Please remember that admittance to the hospital is only through pre-paid online reservations for the specific date and time on our website. You can visit the gift shop without taking the tour during those days. We still have patients hoping to see your smiling faces.
