This reminds me of another experiment. This one to prove crows could hold a grudge:
A scientists went into a forest and began trapping, tacking and releasing 7-15 crows.
Him and his colleague took turns doing this while wearing identicsl masks, at 5 different locations.
Once released each crowd would "scold" the scientist and thereby gather a crowd of crows to drive him away.
Suffice to say, if the scientist, his colleague or anyone else goes into that forest or even near it wearing that mask, the crows go bananas.
Haha, good for them to remember that and keep them out. No one likes crazy birds coming after them. Thanks for sharing.
There's a good doc on this very subject.
Have you ever looked into the eyes of a crow or raven? When they blink it looks like the lens of a camera snapping a photo.
Basically, Crows are a candidate for next "accepted" Intelligent Species XD
Watching the beginning... They were lucky the crows didn't attack the shooters en masse XS
And I think the guy underestimates crows a bit... give them time and they'll be able to associate his presence with the presence of his hunting bird, possibly even which vehicle is his.
