The American Kestrel cannot excavate its own cavity and depends on finding the larger nest holes of woodpeckers for a nesting place. Since these are in short supply, the kestrel population is often dependent upon nesting boxes. Included is an interior perch so the mother and babies can keep a sharp eye for their next meal. The house should be placed in an open area, such as in a meadow or along a highway. Wood chips are included. As with all our nest boxes, the design includes appropriate ventilation, drainage and opens for easy clean-out. Sustainably grown 1" thick Eastern White Pine provides superior insullation. Hand crafted with pride in Maine. Repair or replacement of any defects in manufacturing or materials upon return of any defective item to Coveside Conservation Products.
