It’s the Big garden Bordwatch – organised by the RSPB – from Friday, January 28 to Sunday, January 30.
Last year more than a million people took part, recording birds from the comfort of their own widow. And this year the organisation hopes for a similar response.
Whatever you see – even if nothing at all – you can share your findings with the RSPB.
