| | The Birdhouse Network - Purple Martin |
 | | Purple Martins are a migratory species that breeds along the West Coast and in the eastern and central portions of the United States, and in parts of Canada and Mexico. |
 | | Purple Martins can reach fairly high densities when nest boxes are present; however, in other areas, they can be completely absent. |
 | | Purple Martins are obligate, aerial insectivores; they feed in flight upon flying insects such as wasps, moths, flies, grasshoppers, bees, and ballooning spiders. |
