The UK's epic long-distance travellers
Manx shearwaters are long-distance travellers who seek out the warmer climes of South America before returning to the our wild isles every spring to breed. But the future of these heroic explorers is at risk, and we can play a vital role in protecting them.
They might be a bit clumsy on land, but Manx shearwaters are masters of the air. Gliding low over the waves on stiff wings, they’re like little albatrosses – the two are in fact related – travelling a staggering 6,000 miles to the warm coasts of South America. As they’re one of our longest-lived UK birds, some might travel over five million miles in their lifetime – the equivalent of flying to the Moon and back roughly 10 times!
We’re fortunate to have an estimated 80% of the world’s Manx shearwaters. Although they spend a lot of their lives at sea, they return to breed here each spring, reuniting with their lifelong mate to lay a single egg. They’ve learnt to lay these in underground burrows to protect them from most predators but that doesn’t always keep them safe.
Their eggs are vulnerable from invasive predators such as rats, which are sometimes accidentally introduced to islands with devastating consequences to ground-nesting birds. Once the chick has hatched, it’s risky for the adults going to and from the burrow with their food, so they wait until darkness to return.
The eerie sound of these birds calling and cackling in the dark made Norse sailors believe the Scottish island of Rum was inhabited by trolls. Today, what’s alarming is the future of these incredible birds. As well as predators, they’re vulnerable to the spread of disease such as bird flu, as well as threats to food sources along their migration journey.
Sadly, they’re on the Amber List of UK Conservation Concern, meaning they’re moderately at risk. As the largest global host to Manx shearwaters’ nests, we have a significant role in securing their future. We must protect them from predators and disease as well as safeguarding their food sources and migratory pathways so they can continue to share our waters for years to come.

Discover more about where Manx shearwaters live, the threats they face, and some stories of hope that show we can preserve nature if we take action.
We’re surrounded by over 30,000km coastline and some of the most abundant waters on the planet. We must protect our ocean habitats from an uncertain future.
Our nature is being pushed to the brink by the changing climate, pollution, mismanagement and more. Only by knowing the threats can we work to protect our wild isles.
Our wildlife is amazing - but it’s in crisis. WWF, the RSPB and the National Trust are working together to bring nature back from the brink. We need everyone. Find out how you can go wild once a week and together we can save our wild isles.
