Topic
identification
Identification is the skill that makes everything else possible, and it is mostly about knowing which three features to check rather than trying to take in the whole animal. Most sightings last a few seconds, in poor light, with nothing to give you scale.
These articles work through the reliable marks — the white tail tip, the black ear backs, the low silhouette — and the ones that mislead, starting with coat colour. They also cover the animals foxes get confused with, which varies enormously depending on which continent you are standing on.
What these articles will let you do
- Separate a red fox from a coyote, a grey fox, a dog and a cat at a glance
- Judge size honestly, allowing for the winter coat that fools almost everyone
- Use eyeshine, gait and tail carriage when the light has gone

Identification: common questions
- What is the difference between a fox and a coyote?
- Size, mainly: a coyote weighs 9–20 kg against a fox's 5–8 kg and stands roughly twice as tall. Coyotes are grizzled grey with a black-tipped tail carried low.
- Are all foxes red?
- No. Red foxes occur in red, sandy, grey-brown 'cross', silver and near-black forms. Coat colour is the least reliable identifier; the tail tip is the most reliable.
- How do I identify a fox at night?
- Greenish-white eyeshine, a low body carried close to the ground, and a purposeful trot along a line — a wall, hedge or kerb — rather than a dog's wandering.
