I have not been to South America but am currently planning a trip there for next summer to shoot Perdiz, quail and duck. From my take on it compared to my South African hunt,it can be way more high volume shooting due to a large percentage of your shooting is dove and duck whereas South Africa can have good dove shooting but not in the volume that a good place in Argentina would have. I enjoy hunting over dogs so that is why I spend very little time hunting doves. Nothing wrong with it, just not where my interests are. I think for strictly uplands Africa has South America beat by a long shot due to the variety of species you can encounter in a given day. I would gladly shoot a few birds of several species in a day than a 1,000 of the same. Much more fun for me to roam the country and see all the other wildlife in addition to shooting a variety of pointed birds. I would and will go back to Africa again, but I want to hunt Perdiz, so I figure I will do it this coming year. Then it is back to Africa and maybe Scotland for a Driven shoot.
