It probably is just you because my first thought was how do you tame pigeons? That's like saying a barnyard rooster is tame. This article is blatantly slanted propaganda.
They are tame in that they come running when it is time to eat.
It says they were doves, not pigeons. And you’re right in that they aren’t “tame”. But they are caged then let out and shot as they fly away.
To me it’s no different than putting corn out then hiding up in a tree and shooting the deer after they’ve become accustomed to the free meal. It’s not what I call hunting. I don’t ever remember reading anything about Daniel Boone or Davy Crockett setting up deer feeders. Maybe they did.
I think one day you’ll be able to buy a deer in a cage then let it out and shoot it as it tries to run away.
I’m looking for a lake that has scuba divers placing fish on hooks. I’m sure I could catch my limit real fast.
