There are several subspecies of American Kestrel spread across North America, each adapting to its environment. These differences highlight the kestrel’s ability to thrive in varied landscapes from open fields to urban areas.

By knowing these taxonomy details, I can better appreciate the diversity within this species and share accurate information with fellow bird watchers.


The American Kestrel has three recognized subspecies: the nominate, Falco sparverius sparverius; the western (F.s. paulus); and the southeastern (F.s. peninsularis). Each subspecies exhibits slight variations in size and coloration due to their geographical distribution across North America.

The nominate subspecies is widespread across much of North America, while the western kestrels are found primarily in the western parts of the continent, and southeastern kestrels are located along Florida and its surrounding areas.

These subtle differences can help birders identify local populations and gain a deeper understanding of regional variations within this captivating species.

These distinctions may be particularly useful for birders who want to get involved in conservation efforts as they can help monitor specific populations that could be facing unique threats based on their environment.

Signs to look for

The American Kestrel’s small size, long wings, and distinctive hovering behavior make it easily identifiable. Look for their warm, rusty brown coloration with black spots on the upper side and a pale, spotted underside as they hunt for insects in open country.

Listen for their shrill calls often compared to “klee” or “killy.” Males have slate-colored wings and a single black band near the tip of the tail while females have rufous wings and tail with numerous black bars.

When observing them in flight, notice their rapid wingbeats and frequent hovering as they search for prey.

Kestrel calls

The American Kestrel’s call is a series of rapid, excited klee, klee or killy, killy notes. The male’s call is high-pitched and often ends in a wriggly whistle while the female’s call is similar but harsher.

These calls are distinct and can help identify the presence of kestrels in your vicinity. Birders may also hear them making chattering sounds during courtship or feeding sessions, which adds to their unique vocal repertoire.

Knowing these characteristic calls can be helpful for birders when trying to locate or observe American Kestrels in the wild. Understanding their vocalizations adds another tool to assist in identifying these beautiful birds while out birdwatching.

Conservation Efforts

Learn about the threats to kestrel population and how you can contribute to conservation efforts. Join the cause to protect these magnificent birds and their habitats.

Threats to kestrel population

Loss of nesting sites and habitat destruction are major threats to the American Kestrel population. Pesticides also pose a danger, as kestrels consume insects that may have been exposed to these chemicals, affecting their health and reproductive success.

Additionally, collisions with vehicles and structures such as buildings and wind turbines contribute to mortality among the Kestrel population.

Conservation efforts are crucial in addressing these threats. Providing nesting boxes, preserving open landscapes for hunting grounds, reducing pesticide use, and mitigating collision risks can all help support the recovery of the American Kestrel population.

How to help and contribute to conservation efforts

To help and contribute to conservation efforts for American Kestrels, here’s what you can do:

  1. Set up nesting boxes in open areas with few large trees to provide them with suitable nesting sites.
  2. Participate in citizen science projects that monitor kestrel populations and nesting success.
  3. Support organizations dedicated to raptor conservation through donations or volunteer work.
  4. Advocate for policies that protect open grasslands and farmlands, which are crucial habitats for kestrels.
  5. Educate others about the importance of kestrel conservation and ways they can help support these efforts.
  6. Reduce pesticide and herbicide use to protect the insects that make up a significant portion of the kestrel’s diet.
  7. Collaborate with local landowners to create and maintain suitable habitat for kestrels on private lands.


I’ve always been fascinated by birds, especially the American Kestrel. Their colorful feathers and quick movements catch my eye. Let’s dive into what makes these birds unique.

First off, the American Kestrel is a small but mighty falcon. They belong to a bird family known for their keen hunting skills. Some people call them “sparrow hawks.” These kestrels have different looks depending on if they are male or female.

This difference in appearance between genders is called sexual dimorphism.

Males show off with slate-colored wings and a sharp black band on their tails. Females sport rufous wings and tail with several black bars. When flying or sitting still, both stand out against the sky or trees.

The shape of an American Kestrel is designed for agility in flight. They can hover in mid-air when hunting prey like insects and small mammals. Watching them fly is truly mesmerizing!

Their plumage, or feathers, have warm rusty brown tones with black spots above and paler shades below. Such colors offer perfect camouflage among trees and open fields where they hunt.

For those trying to spot one of these beauties, listen for their distinct calls—a series of sharp klee! klee! klee! Knowing this sound helps birders locate kestrels even without seeing them first.

Kestrels face threats from habitat loss but conservation efforts aim to protect these stunning birds. Installing nesting boxes has become a popular way to help since natural cavities are harder to find due to fewer large dead trees standing around.
