Kestrel Now

Unlike many birds, kestrels do not build their own nests. They are "cavity nesters," meaning they rely on old woodpecker holes, hollow trees, or man-made nesting boxes. They are highly territorial during the breeding season and are known for their shrill, repetitive klee-klee-klee call, which they use to ward off intruders or communicate with mates. Conservation Status

Kestrels are easily identified by their vibrant plumage and distinct facial markings. They are one of the few raptor species that exhibit "sexual dimorphism," meaning males and females look different. Males sport slate-blue wings that contrast with a warm, rufous (reddish-brown) back and tail. Females are slightly larger and more uniform, with reddish-brown coloring and dark barring across their wings and tails. Both sexes feature two black "mustache" stripes on their faces, which researchers believe may act like an athlete’s eye black to reduce glare while hunting. Hunting and Diet Kestrel

The American Kestrel ( Falco sparverius ) is a master of contradiction: it is North America’s smallest falcon, yet it is one of the continent’s most fierce and successful predators. Roughly the size of a mourning dove, this colorful raptor brings high-speed aerial precision to open fields, deserts, and even suburban parks. Physical Characteristics Unlike many birds, kestrels do not build their own nests

While the American Kestrel is still widespread, their populations have seen a steady decline over the last several decades. Scientists attribute this to habitat loss, the clearing of "dead" trees they need for nesting, and the use of pesticides which reduces their primary food source (insects). Conservationists have found great success in bolstering local populations by installing "kestrel boxes" in open habitats. Conclusion Conservation Status Kestrels are easily identified by their
