It's funny that people fail to see the "big picture" with events like these, specifically with crows. I see more and more instances where these medium-range predators are becoming more and more brazen in their attacks.
What I really see is a form of evolution. When any animal, be it bird, reptile, amphibian, fish or mammal exhibits traits of higher intelligence, it's a form of evolving. Crows have a higher level of intelligence than a sparrow, maybe not as much as a parrot.
When the birds show signs like the use of a tool to help them obtain food, that's an example.
When an animal bands together with others to fend off a common foe, that's another.
If only humans would start showing some signs of intelligence, it would be more interesting, but we may have peaked as a species.
Oh well, at least we have "Honey Boo-Boo" and "Moonshiners" and the "Housewives of (fill in the mental sesspool) County" to keep us entertained!
