Using magnification lenses on camera traps to improve small mammal identification

Abstract

Detection of small mammals and reptiles using camera traps can be imperfect, and for some species it is almost impossible to confirm species identification using monochrome images because the animals are not sharply focused or distinguishing features cannot be deciphered. We have proof-of-concept evidence that generic reading glass lenses can be used to reduce the focal distance between camera trap and target animal. Adding these lenses to the existing intact camera trap improves image quality and better highlights distinguishing features necessary for accurate species identification and close-up observations.
