Yesterday it rained
most of the day. So it was a nice lazy day of watching Netflix (which is way
better in Costa Rica, so many new movies) and catching up on sleep and
paperwork.
At night we hit the
beach at 8, but find the tide was too high and still increasing. So we postpone
the patrol for an hour or so. Before heading back to the house, we check the
hatchery to see if the nest that was brought to us had hatched. Good thing we
did because there was one baby out of the nest dead and a crab hole going under
the basket and into the nest. I began to dig cautiously into the crab hole
hoping to remove the crab, so the nest could hatch normally. The only problem
was the babies had crawled into the crab hole and the crab was nowhere to be
seen. After quick deliberation, I
decided it was better to take the babies out of the nest and place them in a
bucket than to leave anymore to die from the crab. We found 38 babies out of
the 60 eggs and placed them in a bucket of sand and waited to release them
until they were awake and ready.
An hour later, we
carried the bucket of turtles out to the beach and watched as they ran for the
whites of the waves. It never ceases to
amaze me how such small animals charge the waves with such force and no apparent
fear! After we were sure they had made it to the water safe, we carried on with
patrol not seeing a single turtle or poacher.
Today Lotti came in
at 10:30 to remind me of all the
specifics of how to classify development of a turtle and gave the boys a quick
lesson.
Here are the steps
taken when conducting an exhumation…
- Dig out all the sand above the eggs and return it to the beach.
- Place all the eggs in the bucket and carry the bucket to the beach.
- Dump the bucket out.
- Start sorting the un-hatched eggs from the egg shells
- Count the hatched shells, which should match the number of babies hatched.
- Open all un- hatched eggs and record stage of development.
- Return to the hatchery to dig out another bucket of sand to ensure that all the dirty sand was touching the eggs.
- 2-3 days later re-fill hole with new sand.

Stage 1A: Only sign of development is blood. |
Stage 1B: Small fetal turtle |
Stage 2: Fetus still half the size of a baby turtle. |
Stage 3: Would have been just about ready to hatch |
During our
exhumation, we found one more live baby which we released after dark. We also
determined that all 18 un-hatched eggs had arrived to a late stage of
development and had the nest not faced so much trauma, it probably would have
had a fantastic success rate.
