In 1997, just 11 male Bitterns boomed around the UK. The RSPB’s members have been instrumental in bringing this bird back from the brink by supporting the creation of new reedbeds. Over the past thirty years, this species has bounced back.
It’s been another record-breaking year for Bitterns in the UK with 283 booming males recorded in the latest results from the RSPB and Natural England, a 20% increase from the previous survey and the biggest jump since monitoring began in 1990.
On the fringes of a reedbed, a buff-brown heron skulks at the water’s edge. His plumage is the perfect camouflage against the golden vegetation. He’s a stealth hunter and on the lookout for Eels, fish and amphibians. After catching his prey, he disappears into the dense reeds.
Despite being so difficult to see, the male Bittern is the loudest bird in the UK. His deep booms rumble through the reeds and can be heard up to three miles away! This foghorn-like call is a serenade to passing female birds and is an effective way of marking his territory.
The peak time to hear Bitterns booming is from March through to May, but early birds can be heard staking out their patch throughout February.
