Bird of the Day: Sage Thrasher at Mono Lake
If sagebrush is a good environment for Sage Thrashers, Mono Lake is an excellent place to be finding them. The Mono Lake basin has hundreds of square miles of sagebrush, as well as Mono Lake itself, a huge salty lake filled with fairy shrimp and brine flies. It is an important stop on the migratory routes of millions of birds. The lake environment was threatened by the diversion of its feeder streams into the Los Angeles Aqueduct in the 1940, but a 1994 legal agreement means that the situation has stabilized, with a new goal of establishing a lake level 25 feet higher than its 1982 low point.
