Blackbird populations in southern England and Greater London have plummeted in recent years. The Usutu virus, first detected in the UK in London in summer 2020, is thought to be a factor behind their decline.
The British Trust for Ornithology (BTO) has asked the British public to contribute to their Blackbirds in Gardens survey to help understand how they are faring.
How are the blackbirds where you are? Have you noticed any changes in their number compared to previous years? Have they declined, increased, or stayed the same?
