How to choose
Start with the subject in the photo
Wild animals often leave clearer evidence than sightings. A footprint, nest, feather, opening in the ground, or other field sign can narrow the possibilities when the right visible details are compared.
Start with the identifier that describes the subject itself. Each tool uses a dedicated set of clues, so a track photo is evaluated differently from a nest, egg, feather, bone, or burrow photo.
Include scale
A ruler or familiar object near the subject can make size and proportions easier to compare.
Avoid disturbance
Photograph wildlife evidence in place and keep a safe distance from nests, eggs, dens, and waste.
