i use a wall mounted dispatcher, its like a very blunt guillateen, it does all birds easy but with geese turkeys you need someone to hold the bird while you close the jaws with 2 hands. it is also perfectly legal and was in a PP Mag and ive often used it is the use of an air pistol at point blank range under their chin aiming into the brain area, clean quick and works well, the pellet goes in under the chin and out though the top of their head which aids bleeding. you hold the bird so the top of the head is on the soft ground and chin upwards so the pellet ends up in the dirt... theres no pleasant way to kill a bird.
