Hi Colum:
The hatchlings of green are easy to detect compared with olivacea, by size, morphology and color.
The split in two nests is good when the nest is over 120 eggs, and improve the survival because the weight of the upper eggs in the nests is decreased, also the size of the hole of the nest must be of apropriate size.
Change of nesting place is justified when the nest is in a wrong place like near to the high tide or in very dry or very wet place.
So you can improve your results if you do a wise choose.
Buena suerte

> Greetings from ARCAS in Guatemala. Roughly a week ago, we had a green turtle nest near our main hatchery in Hawaii, on the Pacific coast of Guatemala. I´m usually skeptical about such reports, but a local fisherman, who was one of the people who found it recognized it as a green as he had seen them when he fished in the open ocean, claimed that it was much larger than an olive ridley with a smaller head. Apparently, the green was hesitating about nesting there and the people who found it "helped" her up the beach by pushing her. Usually when this happens, with olive ridleys, one person usually just picks the turtle up and carries it into the dunes; but this turtle was too heavy for even two people to carry, so it must have been much larger, presumably a green, though I suppose it could also be a loggerhead.
>
> As far as we know, this is the first recorded nesting of a green or loggerhead in Guatemala! Greens come into and are residents of the Pozo del Nance mangrove estuary 73 kms to the west, and fishermen report incidental catches of greens far out to sea, but we have never had a report of a green nesting in Guatemala.
>
> We collected the eggs and reburied them in our Hawaii hatchery. There were 96 eggs in total. According to our staff at the project, they were larger and tougher than olive ridley eggs, but smaller than leatherback eggs.
>
> We are planning on photographing the hatchlings and taking DNA samples of the hatchlings when they hatch. We have several questions:
>
> - We´ve already buried the eggs in two nests of 48 eggs. How deep should they be (have been) buried?
>
> - How should we take DNA samples? Can we take them of eggs that don´t hatch? Or partially formed hatchlings?
>
> - What is the incubation period for Pacific greens?
>
> - Can greens be identified by photographing hatchlings, or just by DNA?

> Saludos de ARCAS en Guatemala. Aproximadamente hace una semana, nidó una tortuga verde cerca de nuestro tortugario (vivero) principal en Hawaii, en la costa pacífica de Guatemala. Soy generalmente escéptico acerca de tales reportes, pero un pescador local, que fue uno de las personas que la encontró, la reconocía como un verde como él los había visto cuando él pescaba en el océano abierto, reclamó que fue mucho más grande que una parlama (L.o.) con una cabeza más pequeña. Aparentemente, el verde vacilaba acerca de la nidificación allí y las personas que encontró que la "ayudaba" arriba la playa empujandola. Con las parlamas, una persona generalmente la recogen y los llevan a las dunas, así que debe haber sido mucho más grande que una parlama, presumiblemente un verde, aunque supongo que también podría ser una cabezona.

> ¡Por lo que sepamos, esto es la primera nidificación registrada de una tortuga verde o cabezona en Guatemala! Las verdes entra en y son residentes del estuario de manglar conocido como el Pozo del Nance a 73 km al oeste, y los pescadores informan la pesca incidental de verdes mar adentro, pero nosotros nunca hemos tenido un informe de una anidación de una verde en Guatemala.
>
> Colectamos los huevos y los sembramos en nuestro tortugario en Hawaii. Habían 96 huevos en total. Según nuestro personal en el proyecto, los huevos fueron más grande y más duros que los huevos de parlama, pero más pequeño que los huevos de la baule (laúd). Planeamos fotografiar los neonatos y tomar muestras de ADN cuando eclosionan.
