Charismatic, large swallows, Purple Martins are a beloved and iconic nestbox species in the eastern half of the United States. Did you know they can be found here as well? The Desert Purple Martin (Progne subis hesperia) is a distinct subspecies that times its nesting to monsoon abundance and nests almost exclusively in saguaros or other large columnar cacti. These are “wild” martins that use naturally occurring cavities, while the eastern subspecies is said to be entirely reliant on human-made nestboxes. Desert Purple Martins are extremely understudied with large gaps in knowledge about their nesting, migration, and wintering grounds. Tucson Audubon launched the Desert Purple Martin project in 2020 and has learned so much about these intriguing birds. Very recent discoveries and data results will be shared along with lots of video and audio that showcases the charming and fascinating Desert Purple Martin.
