Loads of Europe's birds are under threat from the damage we are doing to our environment, experts have warned.
A report called Birds In Europe says 43% of the continent's bird species are in danger from climate change, farming methods or building projects.
Conservationists fear that some of the species may die out completely.
British birds at risk include the house sparrow, starling, wood warbler and corn bunting. The report was the first survey of its kind for 10 years.
