Rare bittern population highest in Somerset
- Published
Somerset is home to England's largest bittern population, the Royal Society for the Protection of Birds has said.
In its latest survey, the RSPB said 20 males of the rare species had been recorded "booming" at Ham Wall nature reserve near Glastonbury.
The elusive heron-like bird became extinct in the UK in 1886. The figures show the UK population is now at its highest since the 19th Century.
Experts say the recreation of reedbed habitat has led to the increase.
Bitterns are well camouflaged and hard to spot, but mating males can be counted from their loud, distinctive boom-like call which carries several miles across marshland.
The survey recorded 140 booming males across 61 sites in the UK this year, up from just 11 males at seven sites in 1997.
'Threatened species'
The RSPB's Martin Harper said: "Thanks to protection under European laws and key partners working together, bittern numbers have been gradually climbing since 2000.
"Bitterns needed conservation on a country-wide, landscape scale and without the support of the EU's Birds Directive, which protects all European wild birds and the habitats of listed species like the bittern, this would not have been possible.

"The bittern success story should give hope that it is possible to recover threatened species and that it makes sense to protect the laws that protect nature."
Bitterns recolonised the Norfolk Broads in 1911, but while numbers rose until the 1950s they then plummeted to a 20th Century low in 1997.
Many of the sites where bitterns have been counted this year are current or former gravel pits, brick pits or open coal mines where reedbeds have been restored, the RSPB said.
