Kestrel

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.

The kestrel’s hunting style is a feat of biological engineering. While they often hunt from perches like power lines, they are best known for "kiting"—hovering in mid-air against the wind by rapidly flapping their wings while keeping their heads perfectly still. Kestrel

Their diet is diverse, consisting of insects like grasshoppers and beetles, as well as small mammals, reptiles, and birds. Remarkably, kestrels can see ultraviolet light. This allows them to track the urine trails of voles and mice, which glow under UV rays, essentially giving the falcon a "treasure map" to its next meal.
