Excluder 2 Ultimate Purple Martin Gourd Modified Crescent
Protect your Purple Martins from owls, hawks & starlings! The Excluder Gourd offers two patented entrance holes (U.S. Patent number 6513454) and the crescent to exclude the European Starling from nesting.
The easy closure cap is a necessity for doing nest inspections. The two center line hole punches on the gourd recommends 5/8 inch distance from the porch to the bottom of the entrance hole, however, the porches may be attached at different levels at the landlords discretion.
All Excluder entrance shapes work well for discouraging the European Starling.
