interesting to see air gun getting votes as ive often recomended it on here with some critisism, quick, clean ive killed all from quail to geese. got mine from a car boot, if it penatrates a bean tin at 2 feet its good enough. anyone interested ... you hold the bird upside down with its head on the soft ground, pistol into its chin aiming towards brain area, pellet passes though the top of head and into the ground leaving a hole to drain the blood. drop it into a cone to drain reload and give it another one.
