Enemies Crows have few enemies. Their biggest enemy, aside from man, is the great horned owl. The owl's advantages are its size, its ability to see at night, and the almost total silence with which they fly. Crows will recognize an enemy, call to every crow within hearing, and rush in, literally mobbing it. Farmers are another enemy.
Crows can do thousands of dollars' worth of damage to an orchard in just a few hours.
They love corn and will pull up young plants, eat the seed from the bottom, and throw the rest away. They've also been known to destroy entire fields of watermelon by poking holes in each one to get sips of watermelon juice. Crows can also be a benefit, of course, by eating harmful insects and grub worms. Crows are very cautious. They fly slow and steady, rather than swiftly or in a darting manner.
