For whatever reason people first attract Martins, they continue simply because they like these birds.
Martins are beautiful, graceful, clean, interesting and beneficial.
Each martin can consume 2,000 mosquitoes a day, making your outdoor living more enjoyable. The only way to attract Martins is to put up a house. Once they accept it, they will return faithfully year after year. Typical colonies range from a few pairs to 20-30 pairs, and some have more than 100 pairs of Purple Martins.
