James Hooper, Dictionary of National Biography… (1912)
“ The bittern was so common in Feltwell Fen that a keeper there has shot five in one day, and his father used to have one roasted for dinner every Sunday. I have found the eggs of Montagu's harrier, and know those who remember the time when the hen harrier and short-eared owl bred regularly in Roydon Fen, and who have taken the eggs of the water-rail in what was once Whittlesea Mere.' He devoted much attention to the preservation of birds. ”
