American Kestrel

A small falcon, hovering over a field ... it's a kestrel

The American Kestrel is the smallest, most numerous, and most widespread North American falcon. This bird is built for speed, its long pointed wings often bent back at the tip. While hunting, kestrels hover above an open field. These days, the lack of suitable nesting cavities, which limits American Kestrel populations in some areas, has lead to public interest in installing wooden nest boxes.

American Kestrel
By Frances Wood

This is BirdNote. [American Kestrels calling]

The American Kestrel – small, numerous, and widespread. [More kestrel calls] Watch for one of these North American falcons perched on a utility wire, bobbing its tail.

True to the name “falcon,” this species is built for speed, with long pointed wings, often bent back at the tip. If a suitable perch isn’t available, American Kestrels will hover above an open field. Facing into the wind, they flap their wings and use their tails to hold their position. From aloft, kestrels watch for insects, small mammals, and reptiles, which they overtake and capture. [Call of a kestrel] Don’t be fooled by their small size – equal to that of a robin – these are fierce hunters. Using their notched beaks, kestrels quickly subdue their prey by severing the spinal cord at the neck.

The lack of suitable nesting cavities limits kestrel populations in some areas.  And this has lead people to install wooden nest boxes. Many states now have kestrel nest box programs, placing boxes along interstate highways. On I-35 in Iowa, there’s a kestrel box nearly every mile, from Minnesota to Missouri. [More kestrel calls.]
  
The kestrels readily adapt to these boxes and return each spring to set up housekeeping. You can find more about kestrels – including photos and plans for a nestbox – on our website, BirdNote.org. I’m Michael Stein.
