Rodent ID

Identifying small mammals in hand can be tricky. Identifying small mammals in blurry camera trap images can be near impossible and can require a different set of characteristics. Some species are glaringly obvious, others are a mix of knowing what occurs in the area and getting the feel for how different species pose or how different flash types reflect off of subtly different fur.

I’ve compiled a selection of sample images of small mammal species that I commonly encounter in Gippsland, the Grampians, and the Otways. Accompanying the images are a few notes to help identify each species.
