Lake Natron is one of nature’s most fascinating sites. The only regular East African breeding ground for the Lesser Flamingo, the lake is one of the most important non-protected sites in all of Tanzania. The high water temperatures (reaching over 120° F) and high salt and mineral contents provide an environment perfect for microorganisms. These red algae are not only the primary diet for the flamingos, they also turn the lake to a beautiful ruby red color. As the waters evaporate, large red salt islands form in the lake. The salt islands are perfect nesting grounds for the flamingos, providing an environment that is safe from predators.
