Outside my window are three oaks. In autumn jays arrive here on acorns. In the morning I noticed a jay on a nearby old apple trees and a young neighbour’s cat stalking her. Bird did not run away, but approached the cat. Then jump to the neighbouring branch and the cat went down to the trunk and walked into the branch. This is repeated. I went to get the camera and photographed from the balcony. Jay still clearly play with the cat, allowing him to approach quite close. Cat abandoned after about 15 minutes.
