They can identify a worm from 300 feet, why would they not be able to do that.

I had a similar thought. Birds are extremely visual animals. They should be good at noticing changes in patterns and such.

It might seem remarkable that they can do this in a structured setting like humans do, but the more I learn about animals… The less remarkable I think this kind of behaviour is.
