Rare 'Booming' Bird Breeds North in 70 Years
28 Sep
Summary
- Bitterns bred at Gosforth Nature Reserve, a first since 1956.
- Male bitterns produce a loud mating call that can travel three miles.
- These rare birds faced extinction twice in Britain's history.
One of Britain's rarest and loudest avian species, the bittern, is believed to have successfully bred at Gosforth Nature Reserve. This event is significant as it represents the furthest north breeding recorded for the species in 70 years, with historical records indicating the last breeding at this specific site occurred in 1956.
The male bittern is renowned for its exceptionally loud and booming mating call, a sound capable of traveling up to three miles. The species has a precarious history in Britain, having been driven to extinction in the 1870s and narrowly avoiding a second extinction in the 1990s. NHSH director Clare Freeman described the breeding as "fantastic news" and one of the most exciting developments for the reserve.
Currently amber-listed due to conservation concerns, the bittern population is showing positive signs. A recent RSPB survey from 2025 recorded 283 males, indicating an upward trend. Because bitterns are highly secretive and remain hidden within reed beds, they are predominantly counted by experts listening for their distinct mating calls.
