We have some native red squirrels in parts of America, too. Not like yours, though. Ours are big and fat, slow, and terrible decision makers. They get run over at incredible rates. The greys seem (barely) smarter.

At least your airgunners get some fun. I didn't realize your reds were nearing extinction.

I'm really surprised we haven't figured out better ways of manipulating these invasive populations. Everything seems ineffective, and sometimes disastrous.
