Purple Martin Decoy #PMD-1 - Increase your chances of attracting purple martins by deploying some of these life-sized, highly-detailed, purple martin decoys. Establishing a new colony is often difficult because purple martins are social or colonial nesters. Martins prefer the company of other martins and are reluctant to be the first to settle at a new site. Decoys are believed to increase the chances of attracting breeding purple martins by helping to create the illusion of genuine colony-site activity, giving investigating martins the confidence to stay and nest. These decoys come with instructions and all hardware necessary for mounting on a variety of different types of housing including gourds and traditional wood and aluminum martin houses.
