Wild Animal Welfare

Wild Arctic Tern Welfare UK

Arctic terns undertake the longest migration of any animal - their UK breeding welfare requires undisturbed colony sites and adequate fish prey.

Key Facts

Arctic terns migrate 70,000+ km annually between Arctic and Antarctic regions
UK colonies breed primarily in northern Scotland, Orkney, and Shetland
Fish availability particularly sand eels determines breeding success in poor fish years
Colony disturbance causes nest abandonment and chick exposure - disturbance-free zones are essential
Climate change is affecting sand eel distribution with direct welfare consequences for breeding terns

Welfare Considerations

Individual arctic terns breeding in UK colonies require undisturbed nesting, abundant fish prey, and appropriate weather conditions for chick rearing. Each disturbance-free breeding colony represents direct welfare benefit for thousands of breeding pairs completing one stage of the world's longest migration.

What You Can Do

Respect arctic tern colony exclusion zones during the breeding season
Support organisations monitoring arctic tern breeding success and fish prey availability
Advocate for sustainable fisheries management that maintains sand eel populations
