Interesting Evaluation Today

No new nests today, but we evaluated a very unique emergence this morning. The first emergence on this nest occurred on Sunday out of a crab hole. This happens every so often. Some hatchlings, while crawling up through the sand with the group, will enounter a crab’s tunnel and take the “exit” for a much easier crawl to the surface. This crab hole emergence was unusual because the crab hole from which the hatchlings emerged was at least a foot away from where we knew the clutch was. Subsequently, there was a second and larger emergence, right where we knew the clutch would be. We evaluated the nest this morning by digging into the larger, second emergence, first, finding 128 hatched eggs, 11 unhatched eggs, 5 dead hatchlings and 7 live hatchlings. Next, we dug into the crab hole, the site of the first emergence. We opened the tunnel all the way to the clutch area, finding 8 more dead hatchlings and 2 more live ones.
