Have you heard Britain’s loudest bird? Bitterns are beginning to boom at many of our nature reserves. 😃 At Lancashire’s RSPB Leighton Moss, which boasts the largest reedbed in North West England, these elusive heron-like birds can be already be heard booming across the reserve and Morecambe Bay. Did you know the female Bittern can hear the male’s mating call from up to 3 km away? Let us know if you’ve heard any booming Bitterns at RSPB Leighton Moss or your local reserve!

Their ‘booming’ has been described as a giant gulping or the sound of blowing on the top of a glass bottle (aka a very strange noise).
