Predator guards help prevent jays, cats, and other mammals from reaching into a bird’s nest box. This is a great way to upgrade your existing birdhouse by making it safer for nesting birds. The extra ¾-inch thickness of these predator guards creates a longer tunnel into the nest box to prevent other wildlife from reaching into the nests. They are made from natural wood that is easy for bird’s feet to hold on to. The 1.5-inch diameter hole appeals to Bluebirds and any smaller cavity nester. The 1.25-inch predator guard fits Nuthatches and smaller birds such as Wrens and Chickadees. Made in the USA.
