Osprey numbers are on the up
Rare birds are doing well in Britain, with most of them increasing in number over the past 10 years, according to a new report.
The skylark and kestrel are among the birds helped by conservation projects.
Five types including the osprey and white tailed eagle had become extinct in the UK. They have now been successfully reintroduced.
But most of Britain's common types of bird like the starling, nightingale and cuckoo are going down in number.
This is happening for a number of reasons including farming and changes to the land where the birds live.
Bird expert Dr David Noble says: "What we need to do now is to continue the good work and use some of the lessons we have learned to help our more common birds."
The research has been done by conservation groups.
