When it comes to attracting purple martins, the best way is by providing housing. With this specific type of bird, location is an important consideration. Purple martins love to soar, so their home should be at least 40 feet from any groves of trees or major structures. However, purple martins also love people, and it will only aid you in attracting them if you place your bird house within 100 yards of your home. Starlings and english sparrows can be a problem, as they often try to move into the houses you have designated for the martins. Traps are a solution, or you can simply have enough homes to accommodate for all the birds. It has often been discussed whether purple martins are most apt to nest in the type of structure they were born in. To have the best chance of attracting these birds, offer both gourds and aluminum homes. Decoys can also be a simple way to start introducing martins to your new birdhouse. With a little patience, you can soon have a whole flock of purple martins in your backyard.
