I used to hang out with behavioral psychology grad students (BF Skinner types) who did a lot of research with pigeons. They transported the birds head-down in juice pitchers with air holes punched at the bottom; they just held the pitcher up to the cage and the bird would jump into it, sometimes so hard they would knock themselves out. They loved that lever-pressing shit - it helped that they were kept at 80% of their normal food intake to maximize the reinforcing effect of the pellets.
I knew an ornithologist that would stuff the birds into old socks because it kept them calm.
Yes. They were washed….
Maybe kitty is helping with banding?

So they were starving the birds? Kinda messed up.
