One of the earlier visitors to our brand new bird feeder was most definitely not hugely welcome.

On the face of it, I don’t mind feeding the squirrels. (Protecting red squirrels around Nottingham might be a lost game.) The reason they’re so unwelcome is that they’re quite violent, and will shoo off the birds whenever they want access to the nuts.
They take mouthfuls of peanuts and then they bury them in my own garden! The entire container full of nuts disappears in a couple days. They’ve managed to knock off the peanut feeder a number of times (I’ve not seen how they do this, but I’m sure it’s them).
The hunt begins for a squirrel baffle.
