Water diversion, groundwater pumping, unmanaged grazing and invasive plants have diminished the riparian habitat. The bird relies on surface water and moist soils from May through July for raising young. As part of ongoing efforts to recover the bird, NRCS has worked with the U.S. Fish and Wildlife Service (FWS) to expand conservation work throughout riparian zones in the arid Southwest, including Arizona, California, Colorado, New Mexico, Nevada and Utah.
