Unwelcome intruder

A Pigeon has been roosting  in a tangle of Cotoneaster branches at just over head height above the path which runs beside the garage. It will sit quietly and not move when we walk underneath it, so we end up shooing it away - but it keeps returning. Had it been any of our normal garden birds we would have welcomed it, but the local pigeon population is rapidly multiplying, so our efforts to deter it will continue.
