Always good to help the wildlife out, just dont attract rats…lol. cameras are good for that. Yup Mike, squirrels live in dreys in the trees, looks like a ball of twigs up high.
As for cameras I use a couple of makes. TPlink are good but not waterproof, i invert a tupperware tub or carry out tub and that can keep it dry. I have a couple of Ali Express waterproof ones, can be hit an miss, sometimes they only last a couple of months.
