Oh, I remember this video! It's really amazing.
I love crows but my heart will always lay with ravens. Corvids in general are highly intelligent and capable of some amazing things! I think you can find some videos and articles on BBC's news site about recorded lab tests with these birds showing off how impressive their bird brain really is. In fact I am reading a book about raven intelligence (Mind of the Raven
), it's really interesting and not too full of technical mumbo-jumbo, if you're curious about them it's a really good book.
