Gonatodes humeralis — Bridled Forest Gecko
Some other names for this species:
Orange-spotted Gecko, Trinidad Gecko
These small geckos were the most commonly-seen lizards in the flooded forest, but that only means that I saw as many as ten or so in the four days that we were at Mamirauá. Partly this was because the weather and geography meant that we only hiked in the forest while it wasn't raining for a total of perhaps four hours, and some of that was earlier in the morning than the lizard's daily activity period. But even so, these lizards were hard to notice, because they are small, well-camouflaged, and shy. The males have red-orange spots and yellow collars, but you have to get quite close to notice these colors in the dappled forest light, and the geckos didn't really want you quite that close.
Here is an account of the four days we spent at Uakari Floating Lodge in the Mamirauá Sustainable Development Reserve.
This species is very adaptable to changes caused by human disturbances; they can be found in nearly every clearing or human habitation in the Amazon basin. This was one of the first ones seen on our trip, living in some trees at a local rum factory along the Amazon river, at which we stopped not so much for the rum but to admire some gigantic blooming water lilies.
This little guy was enjoying the warmth of a light gap caused by a fallen tree.
The next day both a male and a female posed for me on small trees.
A particularly colorful male sleeping on a leaf at night.
This is a particularly bland female sleeping on a leaf at night. A poor photo of a very uninteresting gecko. Nothing to see hear. Move along.
Also a poor photo, but at least this sleeping male is considerably prettier than the previous sleeping female.
