I've just spotted this gem in the new GL26 taken from the 'Diversionary Feeding' section of preventing damage to gamebirds.
Animal by-products legislation does not allow food to be used that would otherwise be used for human consumption, and therefore excludes any animal that has been kept by man, including any fallen stock. Wild animals such as rabbits, game birds, grey squirrels or deer can be used (unless any have been reared for human consumption).
To protect gamebirds (in NE's eyes) it is better to kill a gamebird and then to use the carcass to feed crows rather than to shoot
