Super-Gourd Purple Martin Housing For purple martin landlords, we offer the Super-Gourds. Because they are durable, attractive, roomy for the birds, easy to clean, maintain and monitor, and available with both round and starling-resistant openings, more and more purple martin landlords are switching away from aluminium housing. More importantly, they are discovering that the birds prefer the gourds, and breed more succesfully. The gourd housing comes can be purchased with a pole with pulleys that permit raising and lowering the gourds to monitor the health of the colony. The gourds are made from UV-resistant plastic that will keep the birds inside nice and cool. Not everyone can be a purple martin landlord! Please consult the site of the Purple Martin Conservation Association prior to investing in expensive equipment.
