Inventory--NMB Nest #6, 11th Ave North
The last nest on NMB for the 2013 nesting season was located on a very rainy morning by Donna and Sherry on Saturday, July 13th. 124 eggs, 123 are relocated back from the middle of the beach to the dunes.
45 days later, surface of the nest cracks, soon a crack is completely outlining the circumference of the egg chamber. Sand starts of cave in by day 48 and day 49...
But no evidence of hatchings. Day 50, Early morning check of the beach...
There is evidence that up to 10 hatchlings have emerged. No tracks around nest but further down the beach, closer to the water. Very windy on the beach, large hole from day before is filled in
Sept. 2, Labor Day, nest is checked around 6PM. Bubble has formed, just beyond upper left corner of egg chamber
Soon heads and eyes are visible
But hatchling wait until darkness falls before completely emerging
and racing straight to the water
Next night, nest is again checked around 6PM. Bubble again forms, sand moves
and the outline of a hatchling appears
One hatchlings lays on top of the sand as the sun sets, colors over the ocean
It waits and waits until just as the sun is setting, makes it move and runs to the ocean. Still faint light so pictures were allowed
First Inventory of nest begins at 6:30 on Friday, Sept 6th
Hatchling have dribbled out all week. Wind has continuously filled in all exit holes
Two slight depressions are visible
But inventory is quickly halted when numerous hatchlings are found near the top of the egg chamber. At least 8 hatchlings emerged later that night. The next evening, two more were found around 6PM on the top of the egg cavity.
Three days later, one lone hatchling emerges in the early pre-dawn hours.
and crawls directly to the ocean
Second Inventory starts at 6:30 that evening
Crowd gathers. Connie and Mary dig for the second time
Rob helps dig while Linda explains what is going on
Egg shells are quickly found along with live and dead hatchlings
Holt show the crowd a whole egg
Sharon brings the live hatchlings around so everyone can see. Pictures allowed
but NO Flash
NMB STP Volunteers watch
This little girl loved the hatchlings
This little guy was deformed but had plenty of spirit and
was anxious to crawl
Time to release...Sherry carefully places each one on the sand
The race is on
You go that way, I'll go this way
