This is one thing:
With reports of dive-bombings and other crow-human interactions on the rise in Seattle and Vancouver, some have begun wondering why. For starters, say experts, there are simply a lot more of them. Crow populations are up thirtyfold since the 1970s in some cities—what University of Washington zoologist John Marzluff has termed an “urban invasion.” In Victoria, North America’s crow capital, the population is up more than 500 per cent: 10,000 now call the B.C. capital home.
...this is another:
On a recent weekday, Allana Gustafson was pushing an empty mail cart outside the Dutch Harbor post office when she heard the beating of wings like heavy breathing behind her.When a crow dive-bombs you, you have every right to hurl all manner of insults at the vile and arrogant thing; if an eagle does it, you leave the incident in silence and air of profound respect. Indeed, it is something of an honor to be pecked on the head by a mighty eagle.
Next came a sharp pain. A bald eagle nesting on the nearby cliff had swooped down and carved a rice-sized divot in her scalp, she said, leaving a bloody but superficial wound and serving a reminder to eagle-ridden Unalaska: Don't turn your back on big, nesting birds.
One man said eagles dived at him three times this summer and police on Wednesday posted warning signs near high-traffic nesting areas where eagles are known to dive-bomb passersby.
