We have a hanging bird feeding dish just off of our back porch, approximately 4 1/2 yds.
Chick-a-dee’s, Cardinals etc. My wife didn’t mind the Chipmunk scrounging for seed on the ground beneath but drew the line when he figured out how to climb the arch pole (Shepard’s Hook) and get directly into the dish. A learning error on his part. Sometimes survival of the fittest may require caution when using a new skill set.
Slowly opening the sliding glass door and with an isosceles position, I shot said sunflower seed thief.
Daisy Powerline Model XT15 CO2 BB pistol. Smooth bore approximately 420fps
Not exactly a hunting tool but, nonetheless, apparently adequate for close quarter feeding dish defense.
