Spring Wildlife Guide – SWAROVSKI OPTIK Reveals 5 Elusive British Icons Hiding in Plain Sight

March 2026 – As the British countryside awakens, beyond the familiar spring sightings some of Britain’s most remarkable wildlife is also quietly going about its business, often unseen to even experienced nature enthusiasts.

To mark the start of spring, world-leading optics specialist SWAROVSKI OPTIK has unveiled its Spring Wildlife Guide with a shortlist of the UK’s most elusive wildlife icons. From booming bitterns concealed in reedbeds to pine martens moving through Highland forests, their expert camouflage, stillness and often low-light activity mean these species are often overlooked, even in well-visited landscapes.

The ‘Elusive 5’ to look out for this spring include:

  • The Great Bittern – This elusive wetland bird hides deep in reedbeds, its streaked brown plumage blending perfectly into the vegetation, meaning it can stand in full view and remain unseen. Spring is one of the best times to experience the bittern, when males produce their distinctive booming call across wetlands and patient visitors scanning reed edges at dawn or dusk may be rewarded with a rare sighting.

Best location – RSPB Ham Wall (Somerset), RSPB Lakenheath Fen (Suffolk), RSPB nature reserves and wetlands

  • The Eurasian Otter – Although otters have returned to many UK waterways, they remain shy and fast-moving, often slipping past unseen at dawn and dusk. In spring, cubs begin venturing out with adults and early morning walks along quiet rivers or coastal waters offer the best chance of a glimpse.

Best location – Isle of Mull and the Isle of Skye

  • The European Nightjar – Known as one of Britain’s most mysterious birds, nightjars are superbly camouflaged and rarely seen in daylight. Most active at dusk, they are more often heard than seen, with their distinctive churring call carrying across heathland on warm spring evenings. Quiet observers may see them flying low over open heath and woodland edges as they hunt insects.

Best location – New Forest (Hampshire) or Sherwood Forest (Nottinghamshire)

  • The European Pine Marten – Once close to extinction, this agile woodland predator is slowly returning to parts of the UK, yet remains elusive, moving silently through trees and undergrowth, mostly at night. In spring, adults range more widely during the breeding season, slightly increasing the chance of sightings at dawn or dusk.

Best location- Cairngorms National Park, Galloway Forest Park and the Scottish Highlands

  • The Rock Ptarmigan – Found only on Scotland’s highest peaks, this rare mountain bird is so well camouflaged that it blends into rocks in spring, often remaining motionless as people pass nearby. Spring is the breeding season, when ptarmigan are active but still difficult to detect, adding to the reward of a sighting. Careful scanning of rocky slopes offers the best chance of seeing one.

Best location – Ben Macdui and the Cairngorm Plateau in the Scottish Highlands
