Hawks in Wisconsin – Most Common Species You Can Spot

Wisconsin is filled with magical scenery, luscious forests, planes, and highlands.

How many hawks have you seen in Wisconsin? There are a lot to look at and a lot to identify! See how to identify the hawks in Wisconsin in this article!

Hawks in Wisconsin

According to eBird data, eleven species of hawks are possible in Wisconsin. Most of these hawks are common and easy to see but two species are rare visitors.

It might be easy to see hawks in Wisconsin, but their identification can be a challenge. They have similar characteristics and when the big birds can fly high overhead, it can be tough to get a good look.

To help identify the hawks of Wisconsin, we used eBird data to make a list of eight commonly seen hawks arranged from most common to least common. We also included three rare species that occur in the state and information to help you identify them. We hope this list helps!
