This authentic Cornell Lab of Ornithology sound studio recording has helped thousands of folks become martin landlords when played loudly from outdoor speakers or a boombox. Any martin within hearing range will be lured in to investigate.
Message from our biologist: Keep playing the recording to lure subadults to your housing so you can expand or start your colony. Subadults arrive four to six weeks after the adults arrive. Check our website to see the scout reports to determine when scouts have arrived in your area.
