A hole in a hedge bank rarely announces itself. You spot a dark opening, a scatter of soil, a well-worn path — then the question: badger sett or rabbit warren? The two species often live within a few metres of each other, and rabbits will happily dig alongside badgers. Getting the identification right matters, because setts are legally protected and a disturbed sett may be abandoned. Fortunately, badgers and rabbits leave very different marks on the ground, and most holes can be identified inside a minute once you know what to look at.
A rabbit hole is built for a rabbit. Most entrances measure roughly 10–15 cm across, and a big one might just reach 18 cm. A badger sett entrance is a different order of magnitude: typically 25–35 cm wide and 20–30 cm high, with main sett doorways large enough that you could push a boot in without touching the sides. If you could post a rugby ball through the opening, think badger. If it is barely wider than your two fists, think rabbit.
A quick field test: hold a hand against the opening. Rabbit holes are small enough that one hand covers most of the entrance, your fingertips reaching the rim. A badger hole swallows a spread hand with room to spare — you would need both hands, thumbs touching, to span the width of it. This is the moment most identifications are made, and it is usually enough.
Size alone can mislead at the margins, though. A burrow dug by an adult rabbit in soft, sandy soil may open at close to 20 cm, and a freshly dug badger entrance in loose earth can start smaller than you would expect before it is worn out to its full width. Treat size as a filter rather than a verdict: if the hole looks borderline, the next clues decide it.
Badgers produce a very particular doorway. The entrance is usually wider than it is tall, with a flat or gently dished floor and an arched roof — a squashed arch, or a "D" lying on its back. Years of the same animals pushing through the same gap polish the floor and lower sides smooth, and the base is often visibly worn, sometimes with a shallow trough running out of the mouth where countless feet have scuffed the soil. Look for that tell-tale smear of clean, compacted earth on the floor lip.
Rabbit holes are the opposite: round to oval, frequently taller than wide, with crisp, crumbling edges and no sign of wear. A rabbit does not funnel through the same line year after year in the same way, so its burrow mouth usually looks fresh, fragile and slightly ragged, often tucked under a tussock, a root plate or the lip of a ditch.
The spoil heap tells the same story. Badgers excavate in earnest and push out fan-shaped mounds that can spread a metre or more from the entrance, studded with stones, roots and clods of subsoil. Rabbit spoil is a modest scatter, rarely more than an arm's length across, usually finer and dumped close to the hole.
Entrances are only half the evidence. Step back and read the neighbourhood.
Single holes are rarely the whole picture, and the way holes cluster is itself a clue. Badger setts come in recognisable ranks:
Rabbit warrens can be just as large, with dozens of entrances in a single bank, and they are used in a similarly busy, communal way. Counting holes will not save you here. What separates a warren is that every one of those entrances is small, the spoil is slight, and the ground between them is laced with narrow, well-trodden runs. A warren reads as a honeycomb of small doorways; a sett reads as a handful of big ones.
Fox earths are the usual impostor. They are similar in size to a smaller badger entrance and often sit in the same kind of bank, but a fox earth usually has a single untidy entrance, a strong sweet musky smell, and a scatter of bones, feathers and prey remains nearby. Badgers keep their doorsteps remarkably clean by comparison. Rabbits sometimes enlarge old burrows, and badgers sometimes take over old warrens, so genuinely mixed ground does exist — look for the largest, most worn openings and judge those.
Use the two-out-of-three rule. If the opening is large, the spoil is generous and there are latrines, call it a badger sett. If the hole is small, the spoil is thin and there are pellets strewn about, call it rabbits. When the evidence is genuinely mixed, do not guess in the field — return at dusk and watch quietly from a distance, or set a trail camera for a night or two. Both species are creatures of habit, and a single night will settle the question.
Never put your hand into a hole, never dig one open, and never block or obstruct an entrance. Whatever dug it, something is living there.
The legal position is worth knowing before you survey anywhere. In the UK, badger setts are protected under the Protection of Badgers Act 1992: it is an offence to damage, destroy or obstruct a sett, or to disturb a badger while it is in one. Rabbits carry no equivalent protection, but that does not make it acceptable to dig out a warren on land where you have no permission — and if you are even slightly unsure which species you are looking at, treat the hole as a sett and leave it alone. Record what you see, note the grid reference, and pass it on to your county mammal recorder or local badger group. Those records do real conservation work; a hole dug open out of curiosity does not.
