Wildlife of Scotland: Eagles, Red Deer, Wildcats and More

Scotland’s wildlife at a glance

Red deer: monarch of the glen

The red deer is Scotland’s largest land mammal and the biggest native land animal in Britain. Scottish stags average about 1.2 m (4 ft) at the shoulder, and Scotland holds most of Britain’s wild red deer, from the Highlands to the islands of Rùm, Jura and Arran. In summer they climb to high corries to escape biting insects; in hard winters they come down to the glens.

The rut in late September and October is one of Britain’s great wildlife spectacles. Stags roar, parallel-walk and clash antlers to win groups of hinds, and the sound carries across the glens at dusk. Glen Etive, Glen Torridon, Rùm and the Cairngorms are all good places to watch, keeping a safe distance from rutting stags. Our red deer profile covers their life cycle.

Red squirrels, pine martens and mountain hares

Most of the UK’s remaining red squirrels live in Scotland, especially in the Highland pinewoods, Aberdeenshire, Perthshire and Dumfries and Galloway. Gray squirrels have spread into the Central Belt and the south, so conservation projects work to keep grays out of the north.

The pine marten, a chocolate-brown tree-climbing relative of the weasel with a creamy throat patch, has spread back across much of Scotland after a century of persecution. Studies suggest that where pine martens return, gray squirrels decline and red squirrels recover, possibly because grays spend more time on the ground and are easier for martens to catch. Some wildlife hides in the Highlands put out food so visitors can watch martens at dusk.

The mountain hare is Britain’s only native hare. In the Highlands it turns white in winter, a coat that stands out on bare hillsides when the snow is late. Mountain hares have been fully protected in Scotland since 2021.

The Scottish wildcat

The wildcat is Britain’s only native wild cat and one of Scotland’s rarest mammals. It looks like a big, heavy striped tabby with a thick, blunt tail ringed in black. Habitat loss and persecution pushed it back to the Highlands, and the biggest threat today is breeding with domestic and feral cats. So few pure wildcats remain that the wild population is considered functionally extinct. In 2023 the Saving Wildcats project, based at the Highland Wildlife Park near Kincraig, began releasing captive-bred wildcats in the Cairngorms National Park.

Otters, seals and beavers

Scotland is a European stronghold for the Eurasian otter. On the west coast and in the islands, otters live along rocky shores and hunt crabs and fish in the kelp during the day, which makes them much easier to see than river otters further south. Shetland, Mull, Skye and the Outer Hebrides are the best places to look.

Scotland also has large numbers of gray and harbor seals. The Monach Islands off North Uist produce about a fifth of all gray seal pups born in the UK, and the Isle of May in the Firth of Forth sees around 3,000 pups born each autumn. Beavers, hunted out of Britain by the 16th century, were officially released at Knapdale in Argyll in 2009, and a separate population spread along the River Tay. They have been legally protected since 2019, and Scotland had more than 1,500 beavers by 2022.

Golden and white-tailed eagles

Scotland is home to almost all of Britain’s golden eagles. A national survey in 2015 found 508 pairs, up 15 percent since 2003, mostly in the Highlands and islands. Golden eagles hunt mountain hares, red grouse and rabbits, and soar along ridges on wings that span about 2 m (6.5 ft). Read more in our golden eagle profile.

The white-tailed eagle, or sea eagle, is even bigger, with a wingspan of up to about 2.5 m (8 ft). It was persecuted to extinction in Britain, and the last native bird was shot in Shetland in 1918. Chicks from Norway were released on the Isle of Rùm from 1975, and later in Wester Ross and Fife. There are now more than 150 pairs in Scotland, with Mull and Skye the best places to watch them catch fish from the surface of sea lochs.

Ospreys and capercaillie

Ospreys had disappeared as breeding birds in Britain by the early 20th century. In 1954 a pair from Scandinavia nested at Loch Garten in the Cairngorms on their own, and ospreys have nested there in most years since. About 300 pairs now breed in the UK, most of them in Scotland. They arrive from West Africa in late March and April and dive feet first for fish. The Loch Garten Osprey Centre and the Loch of the Lowes reserve in Perthshire have viewing hides. See our osprey profile.

The capercaillie, the world’s largest grouse, died out in Scotland in the 18th century and was reintroduced from Sweden in 1837. It lives only in old Scots pine forest, and numbers have crashed from an estimated 10,000 pairs in the 1960s to only about 530 birds in the 2021–22 national survey, mostly in Strathspey. Capercaillie are extremely sensitive to disturbance, so birdwatchers are asked not to search for them, especially at their spring display grounds. The same pinewoods hold the Scottish crossbill, the only bird species found nowhere else in the world but Scotland.

Puffins, gannets and other seabirds

Scotland’s sea cliffs hold some of the largest seabird colonies in Europe. Atlantic puffins nest in burrows on islands such as the Isle of May, Lunga, Handa and Fair Isle, and at Sumburgh Head and Hermaness in Shetland, while remote St Kilda holds Britain’s largest puffin colony. Learn more in our Atlantic puffin profile.

The Bass Rock in the Firth of Forth is home to more than 150,000 northern gannets and is often described as the largest colony of the species in the world, though bird flu killed thousands of its gannets in 2022. Guillemots, razorbills, kittiwakes and fulmars crowd the ledges of many other cliffs from May to July.

Dolphins and whales

The Moray Firth, near Inverness, has a resident population of bottlenose dolphins, part of a group of around 200 that lives along Scotland’s east coast. Living in cold northern water, they are among the largest bottlenose dolphins in the world, with adults reaching about 4 m (13 ft). Chanonry Point on the Black Isle is one of the best places in the UK to watch them from land, especially on a rising tide when they chase salmon. See our bottlenose dolphin profile.

Off the west coast, minke whales, harbor porpoises, common dolphins and basking sharks feed in the Hebrides in summer, and orcas are seen regularly around Shetland and Orkney.

Where and when to see wildlife in Scotland

• Cairngorms National Park: red squirrels, pine martens, ospreys, red deer, mountain hares and Britain’s only free-ranging reindeer herd, introduced in 1952.
• Isle of Mull: white-tailed and golden eagles, otters and summer whale-watching trips.
• Chanonry Point, Black Isle: bottlenose dolphins on the rising tide, May to September.
• Isle of May, Fife: puffins from April to July and seal pups in autumn.
• Bass Rock, East Lothian: gannets from spring to autumn by boat from North Berwick.
• Isle of Rùm: red deer, white-tailed eagles and a huge colony of Manx shearwaters.

• Knapdale, Argyll: beavers at dusk.

Bring binoculars, keep to paths, keep dogs on a lead near ground-nesting birds and deer, and give eagle nests, seal pups and rutting stags plenty of space. For more on British mammals, see our guide to wild mammals of the UK.
