Ring Ouzel

The mountain blackbird

The ring ouzel is essentially a blackbird of the high hills — similar in shape and behaviour but darker, with a striking pale crescent across the breast (broader and brighter in the male). The male is sooty black with silvery-edged wing feathers that give a scaled appearance in good light; females are browner with a less distinct bib. Both sexes share the same habitat: the steep, heathery, rocky slopes of upland Britain.

Upland breeding

Ring ouzels arrive back in Britain from Africa in late March and early April, establishing territories on moorland slopes. They build bulky nests of grass and mud on rocky ledges, in heather clumps, or in old mine workings. The species is associated with specific habitat — steep slopes with a mosaic of heather, bilberry, and short grass, often near gullies or crags. British breeding is largely confined to Scotland, the Pennines, Lake District, Snowdonia, and the south-west uplands.

Decline

The ring ouzel has declined significantly in Britain over recent decades. Population estimates suggest a fall of 60–70% since the 1980s, making it a Red List species. The causes are complex — changes to upland management, loss of bilberry (an important food), and possible problems on the African wintering grounds and migration routes. Climate change affecting upland habitat and invertebrate prey availability is also implicated.

Spring passage

Migrating ring ouzels pass through lowland Britain in spring and autumn, sometimes appearing on coastal headlands, downland, and even in gardens during migration. These passage birds are often easier to observe than the secretive upland breeders, stopping to feed on berries and worms before continuing their journey.
