This year the Big Garden Birdwatch is 40 years old and to celebrate Jane Markham will be meeting Ian Barthorpe who took part in the very first count when he was seven years old. He is now visitor experience officer at RSPB Minsmere. She’ll also talk to Green Fingered George – a young blogger - who is one of the new generation of Big Garden Birdwatchers. He took part in the RSPB’s latest TV ad which gave him the chance to meet his wildlife hero Chris Packham.
