Start by Reading the Ground, Not the Horizon

Most heathland mammals are nocturnal, secretive, or both. A walk that produces no sightings at all can still be a walk full of evidence, if you train yourself to look down and sideways rather than scanning the distance. Tracks and signs tell you not only who is about, but what they were doing, roughly when, and how they use the landscape. That is far more informative than a fleeting glimpse of a rump disappearing into bracken.

The best surfaces are soft mud at gateways and stream crossings, silt along track edges, sand on bridleways, and — the gold standard — a light dusting of snow or a crisp frost that holds a print for days. Before you start, note the weather and how long ago it last rained. A sharp-edged print in damp mud is likely from the previous night; one with crumbled edges and a film of dried silt could be a week old.

Footprints: The Clearest Clue

Learn three broad patterns and you can sort most finds on the heath reasonably quickly.

• Cloven hooves. Two neat cleats. Red deer prints run around 7–9 cm long; fallow and sika are similar; roe deer are much smaller at roughly 4–5 cm, and muntjac smaller still at around 3–4 cm. On soft ground the dewclaws may show as two dots behind the hoof, which happens when an animal is running or on heavy going.
• Five toes with a broad pad. Badgers leave a wide kidney-shaped pad and long, blunt claws on the front foot, often with a clear line of prints because they walk with a purposeful, rolling gait. Badger tracks are noticeably wider than a fox's and the claws are much more prominent.
• Four toes with a triangular pad. Foxes show a slim, pointed pad with small claw marks, often in a near-straight line. Dogs are similar but broader and messier. Cats — including feral and domestic — usually leave no claw marks and have a rounder, fuller pad.

Rabbits and brown hares both show four toes on each foot, with hares much larger and often leaving fur impressions around the print. Stoats and weasels bound, producing paired prints in groups of four, with a distinctive gap between each bound.

Droppings: Less Glamorous, More Useful

Scat is honest. It tells you what an animal ate, and often where it habitually travels.

• Badgers dig shallow pits, known as latrines, usually along paths, at sett entrances, or on boundary lines. Fresh droppings are dark, soft and slimy; older ones are crumbly and blackish, often with insect remains and fruit pips.
• Foxes leave tapered, twisted scats with pointed ends, frequently on tussocks, stones, or path junctions — a deliberate marker. Hair, bone fragments, feather and berry pips are common.
• Deer produce dark, glossy pellets, usually pointed at one end. Roe and muntjac pellets are small and neat; red deer pellets are larger and can clump into a mass in winter when they eat more browse.
• Rabbits drop round, mid-brown pellets that look sticky and shiny when fresh. Hares leave larger, flatter, more fibrous pellets, often scattered rather than in one place.
• Hedgehogs produce shiny, dark, roughly cylindrical droppings that usually contain visible insect fragments and beetle cases — often found on lawns and path edges.

Burrows, Setts and Runs

A badger sett is unmistakable once you have seen one: a series of large, oval holes, roughly 25–30 cm across, with spoil heaps of freshly dug earth outside. Well-worn paths connect the entrances, and you will often find latrines and bedding material nearby. Setts are legally protected, so observe from a distance, keep dogs away, and never block or enter a hole.

Fox earths are usually smaller and often an enlarged rabbit burrow, sometimes with a faint, sharp smell and remains of prey at the entrance. Rabbit warrens show many smaller holes with scraped earth and cropped vegetation close by. Field voles and bank voles leave telltale runs: narrow, flattened tunnels through grass, with small piles of green droppings and clipped stems along the route.

Feeding Signs and Other Clues

Look for the aftermath of a meal rather than the eater.

• Nibbled vegetation. Voles crop grass short and leave neat piles of clippings. Deer browse creates a ragged, torn edge on shoots and leaves; rabbits bite cleanly at an angle.
• Cones and nuts. Squirrels strip conifer cones down to a bare core and leave the scales in a scatter. Mice and voles gnaw hazelnuts into neat round holes with tooth marks around the rim.
• Bark and antler damage. Deer fray young trees and saplings with their antlers in late summer and autumn, leaving shredded bark and exposed pale wood. Look for rut scrapes in the ground in October.
• Snuffle holes. Patches of turf turned over in small, shallow plugs are classic badger work, often where they have been after leatherjackets or wasp nests.

Getting Your Eye In Through the Seasons

Winter and early spring are the best months for tracking. Bare mud, flooded gateways and frost hold detail beautifully, and vegetation is low enough to reveal runs and latrines. Spring brings burrow activity, with rabbits and foxes cleaning out holes and freshly dug soil at entrances. Summer is weakest for prints but excellent for feeding signs, tracks through bracken and droppings. Autumn is deer season: rut scrapes, frayed saplings and thrashed vegetation appear everywhere.

Carry a notebook, a small tape measure and a torch. Photograph each find alongside something for scale — a coin, a boot, a hand — and note the date, grid reference and surface. Keep to established paths on fragile heathland, give resting and nesting wildlife plenty of room, and treat every set and burrow as someone's home. Do that, and a silent walk becomes a conversation with the whole heath.
