Once every three or four years, when conditions are right, the lake is covered with the pink birds as they stop flight to breed. The unique color comes from cyanobacteria that photosynthesize into bright red and orange hues as the water evaporates and salinity rises before that process occurs during the dry season, the lake is blue.īut one species actually makes life among all that death-flamingos. The water is oversaturated with salt, can reach temperatures of 140 degrees and has a pH between 9 and 10.5-so corrosive that it can calcify those remains, strip ink off printed materials and burn the skin and eyes of unadapted animals. The lake's landscape is surreal and deadly-and made even more bizarre by the fact that it's the place where nearly 75 percent of the world's lesser flamingos are born. Bats, swallows and more are chemically preserved in the pose in which they perished deposits of sodium carbonate in the water (a chemical once used in Egyptian mummification) seal the creatures in their watery tomb. At the base of a mountain in Tanzania’s Gregory Rift, Lake Natron burns bright red, surrounded by the calcified remains of animals that were unfortunate enough to fall into the salty water.
