Overview

The Manx Shearwater is one of the great seabirds — it migrates from South America each spring, breeds on island burrows in Wales and Scotland, then migrates back. In the Irish Sea, large numbers pass the Sefton Coast, banking and wheeling over the waves with stiff, rigid wings alternating rapid wingbeats with long glides — the 'shearing' flight that gives shearwaters their name. In August, northwesterly winds push good numbers close to the coast at Formby Point.

Where to See It

Offshore from Formby Point. Sometimes in large numbers in northwesterly winds.

Identification

Medium seabird. Jet black above, white below. Stiff-winged shearing flight, alternating flaps and glides, banking to show black then white. Smaller and more contrasting than Fulmar.

Viewing & Photography Tips

Seawatch from Formby Point in August in northwesterly winds. Manx Shearwaters appear in small groups to large flocks, shearing over the wave tops. The black-and-white contrast and shearing flight are distinctive.

Conservation Status

UK Amber List

This species is on the UK Amber List for Birds (BoCC5), indicating moderate concern. Population monitoring and habitat management remain important for its continued recovery.

Frequently Asked Questions

How far does the Manx Shearwater migrate?

Manx Shearwaters undertake one of the longest migrations of any bird — from UK breeding colonies to the South Atlantic (mainly off Brazil and Argentina) and back, a round trip of around 20,000 km. Chicks raised on Welsh islands have been tracked reaching the South Atlantic within weeks of their first flight. They can live for 50+ years and may accumulate over a million kilometres of flying in a lifetime.
