Birdhouse Predator Guard 1-1/2" suitable for Bluebirds / House Finches / Hairy Woodpeckers

This item is 3D Printed using fusible thermoplastic (polymer) filament.

Color:  Gray

Both internal and external surfaces are textured to allow native cavity nesting birds to easily grip the surface...

The predator guard serves to prevent chewing/gnawing predators from enlarging the entrance hole to gain access to the nesting cavity... it also assures proper entrance hole diameter...

The extended entrance tube provides added distance between the predator(s) and the nest box occupants (eggs/young/parents).

The absence of a perch discourages predatory birds such as sparrows / starlings from easily perching themselves at the entrance of the nest box.

Tube length (depth) approximately 1-1/4"

Three wood screws included...


This is an original design... often imitated, never duplicated...

Designed by a birder to be shared with fellow birders and our feathered friends...
