Which type of raptor is often associated with hunting in open fields for smaller birds?

The answer is correct because hawks are commonly known for their hunting behavior in open fields, where they primarily seek out smaller birds. They possess keen eyesight and are adept at soaring and gliding, allowing them to effectively scan vast areas for prey. This makes them well-suited for hunting in such environments, where they can spot movement from a distance and swoop down to catch their target.

While falcons are also skilled hunters of birds, they typically hunt in more vertical, aerial pursuits, often taking advantage of their speed rather than focusing on open field hunting. Ospreys primarily fish and are often found near water bodies, while eagles tend to hunt larger prey, such as mammals or fish, rather than small birds in open fields. Thus, the behavior and habitat preferences of hawks align well with the description in the question.
