If you have permission from the land owner to shoot them you can shoot the birds named under general licences. Rats, rabbits, hares, mice (exept dormice), grey squirels, mink, stoats and weasels. You can shoot game birds but always check with the land owner what he wants you to shoot. Permission need not be written but it is a good idea to carry this incase you are challenged. There is no law which says you may not shoot foxes, but don't as an air rifle is not powerful enough and would be inhumane.
