Mammal Watching in the Lake District

Red deer

Red deer are the largest wild land mammal in Britain and the Lake District holds one of England's better populations. Martindale in the eastern Lakes is the main stronghold — the Dalemain Estate has managed a deer forest here for centuries and the herd is significant. Grizedale Forest in the south holds deer throughout the year. The Caldbeck Fells and parts of the western fells also hold deer.

The October rut is the event. Stags roar, fight, and herd hinds throughout the month. Martindale at dawn in the second week of October is one of the great wildlife experiences in northern England. The stags are visible on the open hillside, the roaring carries across the valley, and the light at that time of year makes every photograph worth taking.

Outside the rut, red deer are most visible at dawn and dusk. They move onto open ground from cover in low light. On the fell tops above Grizedale in November, a herd of hinds on the skyline at first light is a regular sight. Binoculars are enough for most views; a telescope is worth it for the Martindale rut if you want detail at distance.

Otter

Otters are resident on most of the major rivers and lake systems in the Lake District. They were absent or very scarce in the 1970s and 1980s due to organochlorine pesticide contamination of river systems. The recovery since the 1990s has been substantial and otter sightings are now regular across the county.

Leighton Moss RSPB (LA5 0SW) near Silverdale is the most reliable otter site in the region. The open water lagoon hide — the Alan Turing hide — overlooks good otter habitat and sightings at dawn and dusk are consistent through the year, more so in winter when lower water levels concentrate fish. The otters here are used to the hides and will hunt through the viewing area.

On the rivers, look for otters along the Rothay between Grasmere and Ambleside, the Brathay near Skelwith Bridge, and the Kent near Kendal. Dawn on a quiet stretch of river in April or May, when the otter family is active and the light is coming up, is exactly as good as it sounds. Look for spraints (droppings) on prominent rocks at the water's edge as an indicator of regular otter use.

Red squirrel

The Lake District holds the largest red squirrel population in England. Grizedale Forest (LA22 0QJ) and Whinlatter Forest (CA12 5TW) are the two main visitor sites with managed feeders. Haweswater, the Forestry England woodlands above Thirlmere, and the National Trust woodlands around Ullswater all hold squirrels.

Morning is reliably the best time at the feeders. The squirrels are most active in the first few hours after dawn. In autumn they are busy caching food and seen more frequently on the forest floor. In summer they spend more time at height in the canopy, so early morning when they descend to feed is the opportunity.

Pine marten

Pine martens were functionally extinct in England for most of the 20th century. The Vincent Wildlife Trust launched a reintroduction programme in England in 2019 and 2020, translocating animals from Scotland. The Lake District is part of the recovery area and confirmed sightings are increasing in the conifer-rich central fells.

Pine martens are most active at night and at dusk. They are cat-sized, dark brown with a pale yellow-cream chest patch (the bib), and move through the tree canopy with remarkable speed. They are opportunistic feeders — berries, birds, small mammals, eggs, carrion. A bird feeder in the right woodland edge habitat can attract pine martens to close range.

Trail cameras are the most effective way to confirm pine marten presence in an area. If you are staying in a woodland property in the central Lakes, a camera trap placed near the woodland edge or near a bird feeder in September or October stands a reasonable chance. Report confirmed sightings to the Vincent Wildlife Trust to contribute to the monitoring programme.

Badger

Badgers are widespread across the Lake District in suitable lowland habitat. The classic habitat is a sloping woodland edge with well-drained earthworm-rich soil. Badger setts are substantial earthworks with multiple entrance tunnels, recognisable by the spoil heaps of excavated soil and the well-worn paths radiating from the entrance.

The National Trust runs badger watching events at several properties in spring and early summer when badger cubs are emerging from the sett for the first time. These guided events are the most reliable way to guarantee a sighting without having to find and watch a sett independently. April and May are the best months for cubs.

Independent sett watching requires finding an active sett, then sitting quietly downwind of the entrance before dusk. The badgers emerge at varying times depending on season and disturbance, but May to August gives the longest evenings and the best chance of cubs playing outside the sett before dark.

Smaller mammals

The Lake District uplands hold mountain hare in small numbers on the highest fells — mainly Skiddaw and the northern fells above 600 metres. These are animals near the southern edge of their English range and sightings require patience and altitude. They turn white in winter, which makes them easier to spot against snow-free ground.

Water voles are present in some beck systems in the lower valleys. The Eden Rivers Trust runs active water vole reintroduction and monitoring programmes. They are well-camouflaged and require deliberate searching of bankside vegetation on sunny days in the middle of the day when they are most active. The characteristic feeding stations — nibbled grass stems and food scraps on flat rocks at the water's edge — are a reliable indicator.

Stoats and weasels are present throughout the fells, though rarely seen. Stoats can be more visible in winter when they turn white (ermine). Short-tailed voles and wood mice are abundant and draw in the predators, so a quiet sit in moorland or woodland edge habitat at dusk often produces stoat or weasel activity.
