Purple Martin House starling resistant covers are made for the wooden style martin house like the popular T-14 or they can be used on other round hole martin housing.
Starlings are Purple Martins largest predator problem. The design makes it difficult for the larger body starling to enter the martin house.
These PVC templates feature rounded corners with punched screw holes. Rivet on metal houses or use small #6 x 1/2" stainless wood screws not included. You may add 56 stainless screws using the drop down box. (Four screws per plate.)
Templates easily attach to the outside of houses with the original round entrance holes. Some modification may be needed to enlarge the width of the original holes to fit the templates.
