Corncrakes were once widespread across the British Isles but agricultural intensification has removed suitable nesting habitat.
Corncrakes are now a protected species and a range of environmental measures and designations have been put in place to reverse this decline.
The UK population has increased from 478 in 1993 to 1,067 calling males in 2004.
