Although camera traps have historically been used to study endotherms, particularly mammals, recent studies have found them to also be effective for reptile research, given proper conditions. Indeed, Welbourne and colleagues (2015) found them to be as effective as complementary methods for detecting reptiles.

We conducted a study in the Lower Urubamba Region of the Peruvian Amazon using camera traps to monitor mammal use of natural canopy bridges for crossing over a pipeline road between September 2012 and October 2013 (see Gregory et al. 2014 for further description). Unexpectedly, we ended up with numerous records of reptiles, including many of Uracentron flaviceps, which is easy to identify because if its large body size, and records of 17 individuals we have not been able to identify. We suspect many of them to be Anolis species, but they are very difficult to see. We would be grateful for identification assistance from the Anolis researcher community. Below we show pairs of images for each individual: the full camera trap photo and then a cropped image of just the individual. Please e-mail me (GregoryT@si.edu) with the individual number (listed above each photo pair) and any thoughts you have about identifications. Thank you Anolis research community!
