When he was younger and healthier he sat some motion detectors in his yard that alerted him to their presence and went out and shot them. He’s not in any shape to do that now.Good luck! My dad had a major problem with them and tried everything. He even stayed up one night and shot one with his 20-gauge! Ammo was 40 years old so the birdshot bounced off him.
