Thursday, September 25th, Waties Island Nest 08 Inventory

Ariana, Thomas, and I headed out to the island for our last patrol and inventory of Nest 08. We were not disappointed by a beautiful South Carolina sunrise. 

Not surprised by the many bobcat, racoon, and deer tracks, 

We were joined by Leslie, Kim T, and Kathy as well as 15 CCU students for our inventory.  Here they come!

Nest 08 was laid 7/23 by our big girl; 36" lady.  Nest was in situ. This Mama traversed the dunes, navigating around sea oats and grasses until she nested close to the base of a dune.  All during the incubation period, this nest was terrorized by ghost crabs.  We caught and removed 13 of those pesky critters. 

Because this Mama nested so close to dune and grasses, some of the unhatched eggs had roots through them.

The students were all smiles once the work began.  Leslie gave instruction and assigned tasks. Kim and Kathy taught and guided some students in the counting of eggs...

...while Leslie taught and guided other students in how to dig to the nest chamber and gather the eggs.

I was dubbed photographer for the morning.

This nest had 78 eggs hatched; 30 eggs unhatched. This Mamma's hatch success is 71.5% and emergence success also at 71.5%. One unhatched egg was opened and flipper used for the DNA paternity study.

Tuesday, September 23rd Nest 08 - Straggler tracks

 Another beautiful morning on Waties Island.

 

Even though Nest 08 has emerged, it is still checked daily until we do the inventory on Thursday morning.  The Tuesday Volunteers were excited to see that a single hatchling emerged over night.  It was a very determined little one, he had a long way to crawl to get to the ocean.  We tracked him from the nest, lost his tracks in the dry sand and discovered more tracks as we got closer to the wet sand and wrack line - he made it!

Good Luck little one!  

You can see the depression of the nest chamber, and the start of his tracks

The little one took the long way to the ocean.  Did not crawl directly, but a squiggly way

We did lose the tracks in the soft sand, but found them again in the wet sand

Very determined!

You can see how far the little one crawled.

  You can see the DNR post in the background 

 

Our major predator -- but this little one made it to the ocean!

First day of Fall, September 22nd Nest 08 emergence

  You could tell it was the first day of fall on the beach.  It was cool and gloomy, even the ocean was rough.

As Donna and Claudia walked up to our last nest of the season, Donna raised her arms for victory. I couldn’t figure out why they would walk on the hatchlings tracks.  They hadn’t.  All of the hatchlings emerged  to the left of the nest, and once they got out of the dunes they really spread out.  They emerged at high tide, so they had a smooth walk to the water.  This nest emerged on day 61.

Friday, September 19th - Inventory of Nest 07

 It was a great “almost” fall morning on Waties- most likely our last Friday walk of the season with Nest 08 our only remaining incubating nest. We were looking forward to monitoring this last hold out nest, then heading up island to complete the inventory of Nest 07 which emerged on Tuesday, Sept. 16. No signs of of an emergence were present at N08, so we headed up the beach as some early morning fog rolled in softening the landscape and making for another great sunrise.

Nest 7 was discovered by our Sunday team on July 20. It appeared this laying momma had come up on the beach earlier during  the night, but had turned around and returned to the ocean (False Crawl #4) only to return further up the beach and lay her nest at the base of the dune. The body pit was well defined and the nest cavity easily found. Because our momma chose a great location for her nest it was left in situ- in it’s natural position. The nest faced challenges from ghost crabs and one brief wash over due to Hurricane Erin, but there was no evidence of any egg loss during incubation. The nest emerged on day 58 with lots of hatchling tracks observed. 

The Friday team was met at the nest site by Leslie and Barb and Steve with their trucks full of hopeful CCU students and additional patrol volunteers. 

After some on site remarks and procedure review, the history of the nest and it’s incubation was reviewed with the participants.

Leslie provides background information regarding the nest and reviews procedures.

Assignments were made, all were engaged, and a quick and routine inventory was completed.

Sorters

                              

Luckily for the students, 2 live hatchlings were found in the nest. 

After the nest contents were evacuated, sorted and counted, the much anticipated release of the hatchlings was completed to the delight of all.

One of the hatchlings had some difficulty getting himself into the water, so he had a little help from one of the students past the first row of waves.

Results of the inventory: 85 hatched, 23 unhatched, 0 dead, 2 live, 1 wash over. 77.9% hatch success rate, 76.1% emergence success rate. 

A great job by all involved!

Monday, Sept 15th - Nest 09 Inventory

We had a beautiful start to our morning walk with the sun peeking out over a very calm sea.

Nest 09 was originally marked as PN03 at the far end of the island. The crawl, measuring 32” was discovered on Tuesday, July 15. This turtle crawled up and along the face of the dune, then back down again before returning to the water. Much of her track at the dune was obscured by blowing sand. The Tuesday team probed numerous places but did not locate the egg chamber. On Friday, Sept 9, the area appeared quiet with no evidence of activity, just as it had for the previous 58 days. However, just beyond and behind the marked area, numerous hatchling tracks were found leading toward the water from an obvious emergence hole. And just like that, PN03 became Nest 09.

We had 15 CCU Sea Turtle Club members complete the very successful inventory: 91 hatched eggs and 5 unhatched eggs, for a success rate of 94.7% emergence and hatch rate. Duties were assigned for diggers, collectors, and sorters. The process went quickly and smoothly, with the nest found to be 18” deep on one side and 14” on the other.  Unfortunately, we found no live hatchlings

                                             Nest results - 91 hatched, 5 unhatched

Since this was an undetected nest, no earlier DNA sample could be taken. Barb (Waties LOA) carried an unhatched egg down to the water and explained the procedure to the students. Since some biology majors were in the group, she let one of them open the egg, release the contents into the water, and place the shell into a vial to be sent out for research.

After that, all that remained was the removal of the eggs from the site, and then we were ready for the ride back.

                                 Great job by the CCU Sea Turtle Club!
