Russ, I had a similar situation with old Ringo in his last years. First I tried a vitamin pill bottle with the bottom cut out as a whistle megaphone. Later I used the method Craig suggested; just a nick to get his attention, not a disciplinary jolt. He worked well with hand signals until the last year when he had sight in but one eye. Of all his sences, his nose held up the best; he was a bird finder to the end. Fred
Calvin, That was a cream can, now an umbrella can.
