Five kinds of seabirds, like the Arctic tern and the common gull, are now on a list of birds in danger of disappearing from the UK.
These birds are having a tough time because the weather is changing, people are catching too many fish, and some bad animals are hurting their babies.
People who care about birds are asking the government to help, like making special areas for the birds to live safely.
The UK is home to many of these birds, so it's really important to protect them.
