Inventory.....NMB Nest #6

NMB Nest #6 was laid around 58th Ave N, June 28th.  As NMB STP Volunteers Stephen and Melinda started their weekly Sunday morning walk,  they saw a fox digging in the sand, midway down the beach.  A turtle crawl was also visible,  leading up to where the fox was.  They ran up to the body pit, chasing the fox away.  Egg chamber was quickly found by following the digging of the fox, one egg was cracked, and an additional egg was found, abandoned on the beach, up closer to the dunes.  Both shells were used for the DNA sample.

116 eggs were moved to a protected dune area at 59th Ave N.  After contacting, SC Department of Natural Resources, permission was granted to put a cage over the egg cavity as protection from further fox interest.   During the incubation time, fox tracks were seen very often, walking near the cage, checking things out.....

Late Monday night, August 17th, day 50 of incubation, a hole appears near the egg cavity and within an hour the mass exit of hatchlings took place.  Most ran straight to the ocean although a few stragglers seemed to get disorientated by the lights of a multi-story condo complex, the first three floors being an open and brightly lit parking garage.  These few hatchlings turned from the water's edge and headed back up toward the lights.  One hatchling made it all the way up to the side of the condo and was headed toward the street.

Holes do matter on the beach.  One hatchling was being watched as it crawled toward the ocean when it completely disappeared.  Search of the area where the hatchling was last seen, a hole made by a beach umbrella was found and the hatchling was at the bottom of the hole, about 12 inches down.  The hatchling was recovered from the hole and set on it's way to the water.........

Nest early in the evening, May 17th

 Nest on August 18th, after the emergence

Inventory, NMB Nest #5

NMB Nest #5, 15th Ave N.....Laid on June 27.....tracks of mother were first reported by NMB Sanitation at 5:15AM.....Check on the tracks,  a huge mound of sand was quickly seen,  mound turned out to be the nesting female turtle, just starting to dig and lay her eggs.  Mother was watched for over an hour an half....a special treat ...........



Nest depressed on Sunday, Aug 16th  around 10PM and hatchlings boiled out just before 11PM.

Withing 10 minutes all that remained was a nice classic depression




All  seemed to run straight to the ocean and disappear into the waves
but a nest check the next morning, Mary, Stan and Connie found one set of tracks
around the walkway at 15th and then found one, lost hatchling close to the dunes.  
They took the hatchling closer to the water and watched as it revived and swam away






Inventory is scheduled 4 days later, on Thursday.  Storms start to roll through the area just before inventory is scheduled to start.  

A special group, the students from Current Transitions, s a non-profit program providing ongoing life skills classes for individuals with cognitive disorders and intellectual disabilities, arrive just as storm does.







Quick look at the nest, then rain starts






Pause in activity, students go back to bus but rain soon stops
A big rainbow comes out as the students come back to the nest






Stan, Rob and Ingrid start to dig up the egg chamber













A huge thanks to the NMB STP Volunteers who worked with he students, explaining what
we were doing and why
