Why are our British birds under threat?
The UK is home to more than 200 different species of bird, but it's getting harder for many of them to survive here.
A report by conservationists and animal charities have identified some of our most at risk British birds.
Things like climate change are having an affect on sea birds diets, meaning many of them are not getting enough food.
As the sea warms up the fish they feed on are travelling north to colder water.
However, some birds like the Red Kite are doing much better thanks to conservation efforts to re-introduce them to different parts of the UK.
