Back in the 60s, there was a study done with pigeons being able to inspect pills on an assembly line[1]. Didn't end up being implemented in a real world scenario, but pigeons are extremely good at recognizing patterns without losing attentiveness over time. There's a pretty good book[2] on pigeon intelligence for anyone wanting to know more about their abilities. I've an amateur ornithologist (it's a hobby), but never been a huge rock pigeon fan. However, I respect their abilities and how much we underestimate them.
