Where should a american kestrel house go?
Open fields, pasture and farmland with a view. Mount on a smooth metal pole where possible, fit a predator guard, and face the entrance away from prevailing wind. Leave the box up through winter as a roost, and clean it out after each brood.
Watch the nest without disturbing it
Nest box cameras let you follow eggs and chicks without opening the box.

What size hole does a american kestrel need?
The published figure is 3 in, drilled 9 to 12 inches above the floor. Holes this large admit starlings, so monitor the box and remove starling nests, which are not protected. Keep the edge smooth and never add a perch.
How high should a american kestrel house be mounted?
Mount it 10 to 30 feet above the ground. Open fields, pasture and farmland with a view. A smooth metal pole with a predator guard or baffle is safer than a tree trunk or wooden fence post, which cats, raccoons and snakes can climb. Face the entrance away from prevailing wind and afternoon sun where you can.
Where do american kestrels live?
All of North America. Open fields, pasture and farmland with a view. A box put up outside the species' range or in the wrong habitat will simply be taken by whatever local cavity nester does fit, which is often a wren, chickadee or house sparrow.
When should I put up a american kestrel house?
Late winter, before birds start choosing sites in early spring, is ideal. Boxes put up later still attract second nesting attempts and late arrivals. Clean old nesting material out after each brood fledges and again before the next season; many small birds also use empty boxes as winter night roosts.
What should go inside a american kestrel box?
Add 2 to 3 inches of untreated wood shavings. These species bring no nest material of their own, so eggs would roll on a bare floor. Never use cedar shavings treated with oils, sawdust that packs wet, or hay that moulds.
