In Punta Sur park, we have observed an increase and decrease that seems to be constant, that can be explained by this biannual migration. Odd numbered years have more nests and even numbered years have less. This is because a population of breeding females seems to be bigger and the other smaller. The number of nests in 2017 were 1500 aprox, this year we tagged 655 nests. in 2016 they were around 500. We are expecting to double or triple in 2019. But something for sure we will also double and triple our efforts.

Did you know that sea turtles only lay eggs every 2 to 4 years?

That is because the female sea turtles do a lot of work in order to have their babies.


To begin with, the only animals to come out of the sea are females, males never leave the water. Secondly the sea turtles have to drag their bodies that weight sometimes between 400 and 440 pounds (depending of the species) on the sandy beach. They sometimes walk several meters looking for a suitable place, normally away from the shore, with usable sand with enough humidity and no rocks. If the female founds a wrong spot she will stop and start over somewhere else.

Thirdly, after she manages to successfully reach a suitable destination she has to bury the clutch, throwing sand behind her back covering a depth of 2 to 3 feet. The whole process may take 1 to 2 and half hours.

Fourth, the turtle doesn’t just make a single nest – in fact, in one season they can make between 2 to 8 nests, with 80 to 150 eggs in each one!!  That means that a female turtle creates  a new nest every 2 weeks in average. After all this work, the turtle retreats to the sea looking for a well deserved meal and a resting spot.

En el Parque Punta Sur hemos observado un aumento y disminución que parce ser constante, que puede explicarse por esta migración bimestral. Hay mayor cantidad de nidos en los años impares, en tanto que durante los años pares vemos más. Ello se debe a que un año la población de hembras reproductoras parece ser mayor, y  en el otro, menor. El total aproximado de nidos del año 2017 fue 1500, este año marcamos 655 nidos. En el 2016 fueron alrededor de 500. Esperamos se que dupliquen o tripliquen en el 2019. Y es muy seguro que también debamos duplicar o triplicar nuestros esfuerzos.


¿Sabían que las tortugas marinas sólo anidan cada 2 a 4 años?


Ello se debe a que las hembras se esfuerzan mucho para tener a sus bebés.


Para comenzar, los únicos animales que salen del mar son hembras; los machos nunca salen del mar. En sgundo lugar,

las tortugas marinas necesitan arrastrar sus cuerpos a través de la arena de la playa que en ocasiones pesan entre 400 y 440 libras (dependiendo de la especie). En ocasiones recorren varios metros en busca de un sitio adecuado para anidar; por lo genera alejado de la orilla de la playa, con arena utilizable que contenga suficiente humedad y sin rocas. Si la hembra se topa con un sitio equivocado, se detiene y comienza de nuevo en otro sitio.


En tercer lugar, después de haber llegado exitosamente a su destino debe colocar la nidada, echando arena sobre su espalda, cubriendo una profundidad de 2 a 3 pies. El proceso completo puede tardar de 1 a 2 y media horas.


En cuarto lugar, la tortuga no coloca sólo un nido. De hecho, en una temporada pueden colocar de 2 a 8 nidos, ¡con 80 a 150 huevos cada uno! Eso significa que una tortuga hembra en promedio crea un nido nuevo cada 2 semanas. Después de todo este trabajo, la tortuga regresa al mar en busca de una buena comida y un sitio para descansar.
