Surely there’s a way of vermin proofing considering the birds can fly? I’ve been thinking of a bird feeder, I’ve started with a hummingbird one and was thinking about unwanted creatures at the seed feeder if I get one but i naively assumed this would be a solved problem lol
My observation as that there are ways to prevent the vermin from getting to the feeder and eating directly from it, but that birds are generally pretty messy eaters and will spread seed / feed widely across the ground while eating from the feeder and that this is what the vermin end up mostly eating.
