I use an old Red Rock caller based on the old Johnny Stewart cassette deck. About a dozen dekes. I painted the owl decoys shoulder with a splash of bright red so he’d look crippled. Death cry, reveille, & fight are the only tapes I use. Take care with the first one coming in if they come as a flock. You shoot and miss that one and it will carry them all away or go land 100 yds away or so and warn them off. It’s why I usually use the death cry first to try to get them in a few at a time.
