Original Bird Guardian Birdhouse Protector has a unique and clever design that took years to perfect and is the only product available that protects eggs, baby birds and even the adult bird from both ground and airborne attacks. The length and circumference of the tunnel was perfected by naturalists and ornithologists. Prevents predatory mammals and birds from reaching into the birdhouse and destroying the nest and occupants.

This well engineered product will prevent gray / black squirrels, raccoons, opossum and cats from bending their arms to reach the resident birds. (Note: Red squirrels and chipmunks are small enough to enter.) Crows, bluejays, grackles and others have no room to get their shoulders in your nest box!

The Bird Guardian fits birdhouse openings from 1" through 1-1/2." The Bird Guardian is attached with three supplied wood screws. The typical installation time is about 5 minutes. (If the existing nest box has a wood or metal pipe entrance cover, simply unscrew or gently pry off and attach the Bird Guardian for predator protection.)

Patented in USA, Canada and Europe.
