Appletree, I love watching them in the streets having their exchanges, great to see nature doing its thing. Laying close to the ground, screeching away, seemingly unbothered by the large dog closing in, as they are far too busy with their exchange.
Love watching a squirrel too, but have to admit there are a growing number recently, especially around Valentine Court.
Great solution for all is just leave each other alone, i.e don't feed or encourage them, works for me.
