Varmints come in different shapes and sizes. The US style get buried or left out for the buzzards, Coons, foxes, coyotes and skunks I leave for or feathered cleanup crew. Hogs I bury.
Pigeons in Africa are gathered by the local tribes for protein, we were shooting rock pigeons and speckled rock pigeons over the sunflower fields in RSA and the Masai women were picking up birds under the guns, had to shoot only high birds. Their normal diet is a mush made from ground Maze. Doves in Argentina are pretty much the same, orphanages and the poor. The birds carry off 25-30% of the annual grain crop in each country, so, we to shoot and pay to do so, it feeds people in two ways, besides paying the PHs and outfitters. I grew up on a farm, farmers kill the killers. Crows are a special breed of killer, they do not call them a Murder of Crows for nothing.
