Method for making an SREH on a Horizontal Natural GourdFrom: Peter Clement CommentsA solution to those of us who have concluded that large natural horizontal gourds with their deep , dark cavities would be the best way to attract martins to our unestablished sites, but who want SREH s, because of serious competition from starlings. I used a 3 ½ long piece of schedule 40 PVC pipe, which has an exact inside diameter of 3", and I used 3/16" birch plywood for the cling plate. Some type of plastic would probably work fine. This is an untested idea, which needs experimenting with, and which probably could be improved upon. It could be made with or without a cling plate, or with exterior and interior porches. Perhaps the natural surface of the interior neck is the answer to the trouble reported with exiting the slick plastic Troyer gourds.
