Having become extinct as a breeding bird in Britain once before during the late Victorian era, the bittern, a member of the heron family, slowly began to recolonise wetlands in the 20th Century. By the late 1990's however the bittern population was once again in decline and reduced to just 11 males. Once more the bird was facing its second extinction in the British Isles. Today as habitats are improved and wetlands created its fortunes are much improved with well over 100 males now booming their calls across wetlands in spring. Which delights nature writer Stephen Moss, Matthew Clapper from the RSPB and presenter Kate Humble in this extended version of Tweet of the Day.
