Which small raptor is most commonly seen hovering 20 feet above an open field?

The American Kestrel is well-known for its distinctive hunting behavior, particularly the ability to hover while searching for prey. This small falcon often hovers about 20 feet above open fields, using its keen eyesight to spot small mammals and insects below. This characteristic hovering can be readily observed as they adjust their wings to remain stationary in the air, allowing them to survey a large area for potential food.

In contrast, the other raptors listed typically do not exhibit this hovering behavior as prominently. The Sharp-shinned Hawk and Cooper's Hawk are more associated with gliding and agile flight through forested areas to pursue birds. The Merlin, while a small falcon as well, tends to engage in fast, agile flight rather than hovering. Thus, the American Kestrel stands out among these options for its unique and recognizable hovering stance above open landscapes.
