Vorstman's guide
to the
mammals
of Europe

A guide for the field: features, similar species, tracks and signs, and the best moments to look — arranged by order, family and genus.

Scope and method

Mammals are seldom seen and almost never heard; what you find is the sign. Each account in this guide therefore carries not a recording but a block of tracks and signs: the footprint, the droppings and the feeding, digging or nesting traces the animal leaves behind. Each account sets those signs alongside the field marks, the species with which confusion genuinely occurs, and the conditions under which the animal is to be expected: activity, time of day, habitat and range.

The species follow the order of the family tree: by clade, order, family and genus. It shows at a glance why a hare does not sit with the rodents, a hedgehog not with the shrews, and a bat closer to the carnivores than to the mice.

The family tree of Europe's mammals

14 clades, 11 orders, 46 families, 336 species

The tree works down layer by layer: from the main branches of the mammal tree through ever smaller clades to orders, families and species. Every clade has a name — some familiar, some coined only recently. Where the genetic support is weak, it says so.

Source of the arrangement: The arrangement and sequence of orders, families, genera and species follow the Mammal Diversity Database v2.5 (ASM, 28 July 2026); the clades above them follow the accepted phylogeny of the placental mammals.

About this site

Mammals of Europe is an educational site about the mammals of the European continent, made for people who want to go beyond a first identification. It is deliberately lightweight: static HTML, no trackers, no cookies.

Every photograph on this site is under a Creative Commons licence or in the public domain and credited to its author with the licence stated.

On your phone

This site can also be used as an app: with its own icon on your home screen, and without the browser's address bar around it. Nothing comes from an app store — it is the same site, just opened differently, with no install step and no account.

On iPhone and iPad (Safari)
  1. Open this site in Safari.
  2. Tap the share icon at the bottom — the square with an arrow pointing up.
  3. Scroll down to “Add to Home Screen” and tap it.
  4. Change the name if you like, then tap “Add” in the top right.
On Android (Chrome)
  1. Chrome usually shows an “Install app” bar at the bottom — tap it.
  2. If that bar doesn't appear, tap the three-dot menu in the top right instead.
  3. Choose “Install app” or “Add to Home screen” and confirm with “Install”.

Samsung Internet phrases this slightly differently: “Add page to”, then “Home screen”.

The language you get is whichever one you were reading the site in when you added it — for a different language, open the site in that language first and add it from there.

Nothing else changes: the same pages, the same content, still over the internet, just without the browser's own bar around it.

Taking it off again
  • iPhone/iPad: press and hold the icon, choose “Delete App”, then “Remove from Home Screen”.
  • Android: press and hold the icon and drag it to “Remove”, or choose “Uninstall”.
