Expedición 2013 - Nueva Caledonia / Expedición del Gecko Crestado
The yellow crested geckos of the Isle of Pines...
As already mentioned in other posts, basically all the Crested Geckos found on the Isle of Pines where yellow and very little pattern. Only the juveniles or semi adult animals had stripes or a marbled pattern on the back and flanks. We noticed this in all populations on the island.

Crested Geckos, a little history...
The crested gecko was first described in 1866 as Correlophus ciliatus by the French, zoologist Alphone Guichenot in an article entitled "Notice sur un nouveau genre de sauriens de la famille des geckotiens du Muséum de Paris " in the Mémoires de la Société Scientifique Naturelle de Chérbourg.
In 1883 crested geckos was re-classified as Rhacodactylus ciliatus by Boulenger which was undone by Bauer et all in 2012. Very little was known about these geckos at the time and only a few specimen were collected. In 1993 Bauer and Sadlier listed Correlophus ciliatus as probably extinct. This gecko was only known from 16 specimens collected from a single locality on Grand Terre, it was presumed crested geckos were extinct as they had not been seen or collected for over a century (Bauer & Sadlier 1993).

Only in 1994 the gecko was rediscovered on the Isle of Pines by German herpetologists. From only a few specimen Correlopus cilliatus became very well established in captivity over the past few years, and is now one of the most kept gecko species in terrarium today!
Crested Geckos at last!
One of the first Crested Geckos we found was this tailless female. So far we found about six animals which are all remarkably similar in coloration and pattern.
Although the animal appears brownish in the pictures - all animals found had a yellowish appearance.
The red spot on the flank is a characteristic of all animals found thus far.
All adult animals found so far were without a tail. It is known that crested geckos, unlike most geckos, do not regenerate their tails.
In the wild, crested geckos are found balancing on lianas or on top of leaves, at a height of about 2 - 3 meters. They seem to avoid larger trees.
Amazing geckos!
The next gecko we found on of the more mature trees in the forest was a mossy gecko (Mniarogekko chahoua), a large female that unfortunately was missing her tail entirely. This however did not take away of the beauty of this animal.

Even while this female gecko is missing its tale, it remains a stunning animal. The animal is extremely well camouflaged against the mossy bark.

The island reveals its treasures
After several nights searching the remaining primary rainforest of the Isle of Pines thoroughly, we finally found some remarkable geckos.
Remaining patch of primary rainforest in the background.
We scouted the rainforest by daytime and the habitat seemed to be perfect for the Crested Gecko (Correlophus ciliatus) because of the many lianas and lower bushes where these animals are reported to hunt at nighttime. But the many higher and mature trees of the forest made it the ideal habitat for two other members of New Caledonian diplodactylids.

At night, on of the first geckos to be discovered was Rhacodactylus leachianus. The New Caledonian Giant Gecko or Leach's Giant Gecko, is the largest species of gecko on the Isle of Pines and used to be a subspecies (Rhacodactylus leachianus henkeli). It is often commonly referred to as a Leachie gecko (plural Leachies). It is the largest extant gecko in the world.
First Rhacodactylus leachianus spotted high in the trees is an adult female.

Still no sign of Crested Geckos
After two nights of extensive searching for the Crested Gecko we still were unable to find any. This is an indication how rare this gecko really is in its natural habitat!
So far we found several leachies (Rhacodactylus leachianus) and one female mossy giant geckos (Mniarogekko chahoua). These giant geckos live in the taller and more mature trees of the forest, whereas the Crested Gecko (Correlophus ciliatus) occupies the lower trees and bushes.

Finally arrived on the Isle of Pines
Today we will prepare all material and make sure our equipment is ready. We will film the Crested Gecko in the wild and hopefully will come back with never seen footage.
We will keep you posted!
In New Caledonia
We just arrived in Noumea, the capital of New Caledonia.
One more flight this afternoon to the Isle of Pines! It has been a long journey so far...
Almost there
It will take another 10 hours before we land in the capital Noumea. From there it is only a short flight to the Isle of Pines, our final destination.
I will keep you posted!
Two more days!
Right now the Exo Terra team is preparing for the "Crested Gecko Expedition" to the Isle of Pines in New Caledonia. In only two days the team will leave from Brussels, Belgium to the other side of the globe in the South Pacific.
Once on the small island, south of the main island, the team will search for the illusive Crested Gecko. A common name in herpetoculture today, but note that the Crested Gecko was only rediscovered in 1995 after it was presumed extinct for nearly a century.

Expedición del Gecko Crestado
En enero de 2013, el equipo de la Expedición Exo Terra se dirige a Nueva Caledonia, una nación insular en el Océano Pacífico, aún gobernada por Francia. Es el hogar del famoso Gecko Crestado, una de las especies de geckos que hoy en día más se cría en cautiverio.
Hasta hace muy poco el Gecko Crestado se presumía extinto hace más de un siglo después de haber sido descrito en 1866 como Correlophus ciliatus por un zoólogo francés. Fue redescubierto por el herpetólogo alemán Friedrich Wilhelm Henkel y su equipo en 1994.
El Sr. Henkel se unirá al equipo de Exo Terra brevemente en la isla de Île Des Pins, donde el gecko fue redescubierto. El único objetivo de esta expedición es la historia natural del Gecko Crestado y recopilar datos pertinentes para dar una mejor perspectiva sobre cómo mantener y criar con éxito estos geckos únicos.
