California's Salton Sea is hot and smelly - and it's also a Mecca for thousands of wintering birds. This inland sea formed when the Colorado River breached floodgates in 1905, forming a lake 45 miles long. The lake has diminished in size and greatly increased in salt concentration, but a single introduced fish - the African tilapia - persists in abundance. Seabirds visit the Salton Sea to feed on them. The smell comes from occasional massive die-offs of the fish, so abundant that their bones make up the shoreline. Every winter, the salty waters support hordes of water birds, including shorebirds, herons, cormorants, pelicans, and waterfowl.
