Turtle nesting season update by Annabelle

The patrols days for the nesting turtle beaches are quite busy lately as we are now finding a lot of tracks, new nests and have more encounters. We also noticed that the first nests of the season are actually hatching and we had a few opportunities to dig the nests that already hatched in order to collect data for our database and learn more about sea turtles hatchlings behavior.

We dug a nest last Monday that was of a great interest with a lot of information. The turtle nested on September 18th  and we can tell that the hatchlings came out 65 days later. Unfortunately we found dead hatchlings, but also intact eggs with several kinds of embryos, black, grey and white, depending of the maturation stage, and of course rotten eggs as well as eggs predated by crabs. Luckily about 135 young turtles managed to go out of the nest and hopefully went into the ocean!!

Another nice event was to encounter twice the same turtle, the same day, on 2 different beaches: in the morning on one beach, that she left without nesting and in the afternoon on an other one where she layed her eggs: Thanks to the photo identification software! Nina and Michael, who are volunteers from Germany, joined us last week, and were of great help during these days. They took awesome pictures and videos of our everyday work as well as for the turtle identification. Isabella and Keith, students from the Seychelles Maritime School, helped us as well: Keith especially enjoyed staying for 2 hours with a nesting turtle on a sunny beach!! Isabella was strongly interested in collecting data from a hatched nest! Thanks to the team!!
