I know this would vary from locale to locale, but, presumably, there are some animals that do not require a permit to kill (mice in mouse traps, for example). How does this work? Is there a list of “always OK to kill” species?
Edit: Thank you everybody for the replies!
In the 18th and 19th centuries big fancy estates in the countryside would import ‘exotic’ animals to have on their land to show off their wealth. It’s where a few of our deer species come from, pheasants, partridge, the little owl, and the squirrels.
Some others were popular but didn’t naturalise, like peacocks, it’s interesting to think how life would be if peacocks were as prolific as pigeons.
