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?
In England it's illigal to keep a squirrel in captivity, but it's also illigal to release a captured squirrel back into the wild, so the only option is to (humanely) kill the poor fucker.
Did you know both are invasive? I read a study once that our native species of squirrels are extinct and went extinct some time ago.
At roughly the same time rich landowners imported both the Eurasian reds and the American greys. We have decided to conserve the reds as they’re closest to our native reds but it’s very subjective.
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.
