The American Kestrel is North America's smallest falcon, and unlike its larger cousins, this beautiful little bird chooses to nest in cavities (i.e., holes in trees or other objects, such as utility poles and buildings). They will also accept artificial nest boxes placed in suitable habitat, which is open areas such as pastures and hay fields. This Instructable will hopefully help you construct your own safe and secure nest box that will also be easy to clean and maintain. The design is based on plans refined by Dr. John Smallwood and Richard Melvin for use in the difficult environment of Florida, and should be suitable for use everywhere.

This box is also suitable as is for screech owls, and could be scaled appropriately for a variety of other species (wood duck, bluebird, swallows, etc.).

Step 1: Box Plans

Here are the dimensions of the cuts that you will need to make - feel free to reorder them in order to accommodate the quality of your lumber. You'd be wise to make sure important parts, such as the back, front, and top, are cut from board sections lacking cracks or knots.

This Instructable follows the order of steps that I used to construct my boxes, but you are free to mix things up in any way you choose. What seems like a logical and efficient workflow to me might not suit you well, and there are many ways to end up with a functioning nest box.
<p>I actually laid this out as a vector graphic, to scale. So that it can be imported into CNC software (like Vcarve for the Shopbot Alpha). I placed the pieces 0.3&quot; apart so a 1/4 inch bit can be used. This way all the holes and pieces are cut out for you and all you have to do is glue/staple them together. You just need a piece of wood that is larger than 90&quot;x11&quot;.</p>
loved this instructable. My family is starting a vineyard, so encouraging kestrel's is highly recommended. so I had a palette that was the right size to make two from. SO I did.
Well done and a great instructable. I was initially wondering if the size wasn't fairly big but then I realized what a 'Kestrel' was in my langiage ;-)<br><br>I gotto make one like this
I love kestrels!!!
crap, I live in Australia and we only have Australian kestrels here. guess I'll have to wait for an instructable about building an Australian kestrel birdhouse.
Like it! I often see these birds when I'm up working on rooftops and such. I was fixing a water tank (sprinkler system type) about 100' up one day and one of them "hovered" about 10' away for a short while, prob wondering what was I doing up there....they seem to thrive here in the city.
Great work! I may make one for screech owls, there are a fair number in my area. Thanks very much!
Please do! For screech owls, try putting the box up wherever you might see or hear them - they don't mind going into thicker cover than a kestrel would stand, so a box put into a stand of trees might well be used. Kestrels will just pass that sort of situation by if they have to maneuver too much to access the box opening. Good luck!
Nice!<br/><br/>Kestrels are awesome, by the way - they just hover there, facing into the wind, staying stationary relative to the ground to watch for prey. Then they <em>dive.</em><br/>
