Yes I dont think its that they would disturb the birds though - its that they are worried about collisions
Until recently the nests were simply destroyed or so i read in article. It may have been RAF Waddington or Wittering
Up here the issue is cutting for silage - just as the birds get started the grass gets cut - they lay and its cut again - any that have managed to survive then face yet another cut. Not only the cutting but the absolute monoculture of grass - practices must change - or we will lose so much more.
