Britain’s loudest bird has had a very successful breeding year, with 24% more male bitterns recorded doing their mating “booming” noise in 2023 compared with five years ago.
Conservationists for the RSPB recorded 234 males across England and Wales including at 11 new sites. The member of the heron family was mating in areas of new habitat created at the RSPB site Leighton Moss and on the Isle of Sheppey.
