Five seabird species, including the Arctic tern and common gull, have been added to the UK's red list, meaning they're at a high risk of disappearing from the UK.
Climate change, overfishing, and invasive predators are putting a lot of pressure on these birds, leading to fewer and fewer of them.
Conservationists are calling for action from the government, like creating more protected areas for seabirds and limiting fishing in certain areas.
The UK is a vital home for many of these birds, so it's important to take action to protect them and their habitats.
