The American Kestrel, a small falcon species, exhibits several notable behaviors that aid in its identification. Hovering is particularly distinctive; Kestrels are often seen hovering in place while searching for prey, a behavior that underscores their hunting technique. This ability to maintain a steady position in the air, often against the wind, is a key visual cue that can help observers recognize them.

Additionally, bobbing of the head is another characteristic behavior. This action can give the Kestrel a lively and alert appearance while it scans its surroundings. The head bobbing often occurs when the bird is assessing its environment or during courtship displays.

Finally, the pumping of the tail up and down upon landing is a behavior that can also be noted in Kestrels. This action is part of their landing sequence and serves to help them adjust their balance as they settle into a position.

Taken together, these behaviors—hovering, head bobbing, and tail pumping—form a comprehensive set of traits that uniquely identify the American Kestrel in the field. Recognizing all of these behaviors allows birdwatchers and falconry enthusiasts to confirm the presence of this species with greater certainty.
