Why Do Crows Chase Hawks and Owls?
If you've ever seen a group of crows swooping after a hawk, you might wonder — why do crows chase hawks? The answer might surprise you.
It’s no secret that backyard birders dislike finding hawks near their feeders. After all, it’s not like the hawks are there for the seed! Crows aren’t regularly winning backyard birder popularity contests either, but after reading this, some might want to re-think their stance on the all-black, highly intelligent birds. Our experts answered the question: Why do crows chase hawks, and is that behavior typical?
Here’s Why Crows Chase Hawks
Birds & Blooms reader Jan Haddrill asks, “Two crows chased a small red-shouldered hawk through my backyard. Is this common?”
Kenn and Kimberly Kaufman: We might expect hawks to be the kings of the air, but other birds regularly harass them. This behavior is called mobbing. Various birds often approach hawks, making alarm calls and even daring to peck at them. No one has come up with a complete explanation for why they do this. It may serve to draw attention to these predators so they can’t take smaller birds by surprise. In the case of crows, which are intelligent and curious birds, it may be partly a tough-guy way of having fun!
Psst—it’s tricky to identify crows vs ravens, but these key details ensure you’ll never get them mixed up again.
During the breeding season, songbirds such as eastern kingbirds and red-winged blackbirds will flutter up to confront hawks that fly too close to their nests. The hawks mostly ignore the efforts of such small birds. Crows, on the other hand, are big enough that they can actually gang up on hawks and chase them away.
“Mobbing” behaviors might run in the brainy corvid family — Steller’s jays and blue jays do it, too.
Why Do Crows Chase Owls?
“Why would crows chase an owl? I have seen four or five crows flying after and around a barred owl, cawing and squawking, on several occasions,”
asks Mary Leffler of Reynoldsburg, Ohio.
Kenn and Kimberly: Many kinds of birds will harass owls that they discover in the daytime, in a behavior called “mobbing.” Even chickadees will mob little screech-owls. Crows focus on bigger targets like barred owls or great horned owls, and they will also chase hawks and eagles.
