Attract Purple Martins by playing this video load during the migration season. This is a loop of Day Time Chatter and Dawn Song. You can buy a CD from various birding retailers, but I use a Bluetooth speaker connected to my cell phone and play this video. Any martins in the area will hear it and follow the sound thinking there is a nesting sight near by. If the martins do not stay then there is likely something about your housing setup that is not idea to them.

If the video helps, give a like and post a comment letting us know where your colony is located. Mine is near La Grange, Texas! Greetings everyone, good luck!
