If you are worried about hitting birds and their fledglings in the nests it is not the job for you. On average I must hit one a day at least, I have hit sheep, cows, cats, dogs, swans, geese, badgers, red kites, buzzards, a horse and an owl. Only one magpie and one crow though, they are clever birds, the most common is wood pigeons and pheasants, stupid birds, why would an animal try to outrun a 100mph train when it actually has wings I can never work out.
What!? Really?
