Grackles are also very territorial, so having large groups of these birds in trees where there is a lot of foot traffic could cause them to swoop down and attack people on the sidewalks.

Are grackles dangerous?

Grackles like agricultural fields and are more of a threat to crops than crows. As much as they like open spaces, they also live in urban areas, making them abundant virtually everywhere. For homeowners, crop farmers, and property managers, these birds can be extremely dominant and harmful.

How do you stop grackles from attacking?

As we might have mentioned, grackle birds tend to avoid nesting and roosting in areas where they know that there are grackle predators that could attack them. Using a sound repellent is a great idea as it can tell a grackle bird that it's time to move to another place if it doesn't want to lose its life.
