Inventory NMB Nest #5-Windy HIll

Donna, Marilyn and Elmer came across NMB Nest #5 around 43rd Ave S, Windy Hill on July 10th.
103 eggs were in the nest, 102 eggs moved back to the dunes.  1 egg taken for DNA Study.

53 days later, Sunday, Sept 1st, very windy on the beach.  Only evidence of an emergence were a few tracks on the lower section of the beach and reports from beach walkers of hatchlings on the beach around 11;30PM.  No depression, no hole and no tracks were ever seen inside the nest area of at the egg chamber.  Margaret reporting seeing a small hole and one lone set of tracks on Labor Day, Monday, Sept. 12 around 10AM.  These were not here when she passed the nest area about 1/2 hour earlier.  Very hot on the beach, sand was very hot but tracks seemed to go straight to the water.

Egg chamber Monday Morning, small, very slight depression not enough to indicate an major emergence


 Single track deep in the sand, very hard to see, bird tracks cross over it

Another view of single track

Few tracks on the wetter sand, again very hard to see

One hatchling appeared to walk up into the dunes, before turning back to the ocean
 Time to Inventory
No evidence of nest, no hole, no depression

Crowd starts to gather

We have shells
Margaret and Candy have been digging
and found 4 live hatchlings deep in the egg chamber. 
Donna shows everyone the hatchlings
And she shows everyone what a whole egg looks like

One last check of the egg chamber to make sure no hatchlings or shells are left behind
Hatched and unhatched eggs rim the hole

The Fab Four waiting to start their journey 

These kids were fascinated and kept coming back for "one more" look

Maddy  releases  the  hatchlings
And the race is on....

Yes, cool sand

OOPS!!!  Now how do I crawl?

Do I have to go there?
Holt makes sure all made it to the water and disappear
