The wetlands’ diverse habitats—from marshlands to riparian zones—support a multitude of bird species, including migratory warblers, ducks, and even endangered birds like the Least Bell’s Vireo.

Understanding the ecological role of these wetlands requires an examination of their hydrological and vegetative dynamics. As natural water sources become increasingly scarce in southern Arizona, Sweetwater Wetlands maintain a consistent water supply, facilitating the growth of diverse plant life that attracts a wide range of bird species.
