Wildlife veterinarians recently hit an important milestone in their collective efforts to conserve a tiny endangered mammal native to the Mojave Desert. The population of Amargosa voles (Microtus californicus scirpensis), restricted to one small town in Inyo County, is now perilously small, due to habitat destruction, climate change and water diversions created to benefit humans.

Ridgway’s Rail Release

Specify Alternate Text
The Ridgway’s rail is a grayish-brown, chicken-sized bird with a long, downward curving bill and a conspicuous whitish rump. Previously known as the clapper rail, the species name was changed in 2014 to honor ornithologist Robert Ridgway. Three subspecies of Ridgway’s rail are resident in California, all of which depend on mudflats or very shallow water (wetland habitat) where there is both forage and taller plant material to provide cover at high tide. They rely on marsh plants such as cordgrass and pickleweed for breeding and feeding.
