pros and cons of crows

I was watching a murder of crows chasing a hawk away on my place in the ozarks and i was wondering what yall thought about crows the good and bad.

For the good: I find them to be very entertaining to watch outside. I like how intelligent they are, and I like all the neat things they can do. It is rather intriguing.
For the bad: I guess they can be annoying if they take things that we wanted for ourselves.

Here's a cool documentary about crows from online; I think it is pretty cool.



Ooh, and there is also a neat TedTalk about them, too:



Overall, I think crows are pretty cool animals, and it would be neat if we could find more ways to help them and get help from them.
