Nature's Voice

The results of this year’s Big Garden Birdwatch sees the lovely long tailed tit making it back into the number 10 spot on the chart. On this edition of Nature’s Voice Jane Markham examines the results with RSPB conservation scientist Dr Daniel Hayhow.  Nowadays most entries arrive online but in 1979, when it all started, they arrived by post. We hear from Peter Holden who had the task of sifting through and recording the results from huge sacks of mail.
