Raptors

Golden Eagle (Kungsörn (Golden Eagle))

The golden eagle is the supreme predator of the Swedish mountains. Pairs occupy large territories across the fjäll (mountain) region and the boreal forest of Norrland, nesting on cliff ledges and in tall pines. They are year-round residents, enduring the Arctic winter when many other species migrate south.

White-tailed Eagle (Havsörn (White-tailed Eagle))

The white-tailed eagle — havsörn (sea eagle) — is among Sweden's most dramatic conservation success stories. Near-extinction from persistent organochlorine pollutants in the 1960s–70s was reversed by banning DDT; the population has since surged to record levels. These enormous eagles are now a regular sight over the archipelagos.

Other Raptors

  • Gyrfalcon (Jaktfalk (Gyrfalcon)) — The world's largest falcon; rare breeder in Sweden's far north mountains
  • Peregrine falcon (Pilgrimsfalk (Peregrine Falcon)) — Recovering after DDT-era decline; nests on cliffs and increasingly on tall buildings in cities
  • Rough-legged buzzard (Fjällvråk (Rough-legged Buzzard)) — Common in mountain birch zone; lemming-dependent
  • Osprey (Fiskgjuse (Osprey)) — ~3,500 pairs; fish-eating; nests atop tall trees near lakes and rivers throughout Sweden

Owls

Great Grey Owl (Lappuggla (Great Grey Owl))

The great grey owl — Lappuggla (Lapland owl) — is the totemic bird of the northern boreal forest. Its enormous, disc-shaped face functions as a parabolic sound collector, giving it extraordinary hearing. In vole peak years, the population booms; in crash years, birds may struggle to breed.

Other Owls

  • Eagle owl (Berguv (Eagle Owl)) — Europe's largest owl; rare breeder on cliffs and rocky outcrops
  • Ural owl (Slaguggla (Ural Owl)) — Forest owl; aggressive nest defender
  • Hawk owl (Hökuggla (Hawk Owl)) — Diurnal; sits atop spruce tips scanning for voles; characteristic of Norrland forest openings
  • Tengmalm's owl (Pärluggla (Tengmalm's Owl)) — Small, nocturnal; nests in woodpecker holes
  • Pygmy owl (Sparvuggla (Pygmy Owl)) — Europe's smallest owl; tiny but fierce predator

The Crane Migration

Common Crane (Trana (Crane))

The crane migration at Hornborgasjön (Lake Hornborga) in western Sweden is one of Europe's great wildlife spectacles. Each spring (late March–April), up to 20,000 cranes gather at the lake to rest and feed before continuing north to breeding grounds. The fields around the lake become a theatre of dancing, calling, and courtship displays.

A smaller but equally atmospheric migration staging occurs at Kvismaren in Närke and at Tåkern in Östergötland.

Grouse and Ptarmigan

  • Capercaillie (Tjäder (Capercaillie)) — Europe's largest grouse; males weigh up to 6 kg; dramatic spring courtship display (tjäderspel (capercaillie lek)) in old-growth forest
  • Black grouse (Orre (Black Grouse)) — Males gather at communal leks on open ground at dawn, displaying and sparring
  • Willow ptarmigan (Dalripa (Willow Ptarmigan)) — Mountain species; white in winter, brown in summer
  • Rock ptarmigan (Fjällripa (Rock Ptarmigan)) — Higher altitude than willow ptarmigan; true alpine specialist

Seabirds

  • Guillemot (Sillgrissla (Common Guillemot)) — Breeds on cliffs at Stora Karlsö off Gotland (Sweden's largest seabird colony; ~40,000 pairs)
  • Razorbill (Tordmule (Razorbill)) — Nests alongside guillemots at Stora Karlsö
  • Eider (Ejder (Common Eider)) — Large sea duck; breeds throughout the archipelagos; females famous for lining nests with supremely insulating eiderdown
  • Arctic tern (Silvertärna (Arctic Tern)) — Migrates from Antarctic to breed in Sweden; the longest migration of any animal
  • Puffin — Small numbers breed on the west coast islands; more common on the Norwegian side
