There have been a trend in presentation of challenging driven birds, the higher the better the presentation. How high is too high? Is it sporting to use these birds as target practice? ...But to only shoot at high birds and possibly wounding them is not ethical in my humble opinion.
Ethics is in the eyes of the beholder. I just spent the last 6 weeks in
your home state of Texas where deer feeders on timers abound, and near San Antone, in the "Hill County," all the deer and exotics are crammed in behind eight-foot fences where "sports" pay
mucho dinero to shoot their big game on the clock when the feeder spreads its bait. To paraphrase the man from Austin TX, "How challenging is it to shoot at a flock...[of hapless caged deer trained to feed at the appointed hour]...you're bound to knock something down..." Methinks that there are sporting issues closer to home in Texas than worrying about "flocks of hundreds and even thousands" of doves that are farm pests in Argentina. But having a "humble opinion" about shooting in a foreign country half a world away makes me wonder if maybe a little bit of local (Texas state) retrospection (hand wringing?) might not be time better spent...shooting fenced deer at a feeder: Gimme a break! And worrying about pen raised chickens released according to a controlled template and schedule for "sports" pretending to be Lord of the Manor in days of yore...so what. As the old farmer said as he lifted his cow's tail, "It's all a matter of taste." EDM
