When a flock of crows began antagonizing an owl in my neighborhood, we could hear the commotion from blocks away. It was late morning, a time when owls typically sleep.
Dozens of crows swarmed the owl as it moved from a tree branch to a rooftop to a fence post. The owl seemed old and was missing an eye, and at times it seemed as though it was bracing itself when the crows darted close.
The crows antagonizing the owl were exhibiting mobbing behavior. In the past 50 years, more scientists have become interested in researching mobbing behavior, and they say it can be an important defense against predators.
What Is Mobbing Behavior in Birds?
Mobbing typically occurs when prey realize a predator is dangerously close. They work together to harass the predator and drive it from their territory. Mobbing can occur among other species including mammals.
