| | Purple Martin |
 | | We tend to clump the name Purple Martin into one group, but actually there are three sub-species of Purple Martins. |
 | | These are known as: Progne subis subis, who breeds in eastern North America and in eastern Mexico, Progne subis Hesperia, who breeds in the deserts of Arizona, western Mexico, and Baja, California, and Progne subis arboricola, who breeds along the Pacific coastal regions of the United States and Canada, and in the Rocky Mountains. |
 | | The Purple Martin is the largest of the swallows, measuring 7 ½" to 8" long. |
