Squirrels are simply tree Rats - if you have never witnessed the carnage they cause to our native Wildlife then you need to get out in the countryside a lot more. We have been shooting 200 ish /year for the last 3-4 years due to a dramatic decline in some bird species - finally we are seeing Nuthatches and Treecreepers returning to our 5k woodland - EVERY opportunity to shoot a grey should be taken.
