The legs of the Lesser Flamingo are tough and can withstand the damaging effects of the water allowing them to build their nests in spots that are protected from predators. It is very difficult for predators to cross the hot, caustic water of Lake Natron since the underlying mud is thick and the water can damage their skin. Watch this video to learn about the Lesser Flamingo breeding and nesting habitat in Lake Natron, Tanzania: For example, over 2.5 million Lesser Flamingos ( Phoenicoparrus minor), which amounts to approximately 75 per cent of the global population, breed and nest along the mud flats and small islands in Lake Natron. The two most common types of salts that occur in these lakes are sodium chloride, which is the same as the salt used in our food, and sodium carbonate, which is also known as soda ash and is the reason these lakes are called soda lakes.ĭespite the harsh nature of Lake Natron, some species do live and feed in this lake and have adapted to its low water and high temperature and salinity levels. The water in these lakes is not only salty, but also strongly alkaline, making it harmful to most plants and wildlife.

This is one of the only alkaline lakes in Africa and its waters do not flow into other lakes and oceans. Being one of the few animals that can survive. In addition to this species, tilapia also occupy the lake’s hot springs. The reproduction of flamingos grows every day, since the greater the salinity of the lake, the greater the number of bacteria, and consequently, the flamingo nests increase in the region. They manage to survive in this region and feed on the cyanobacteria in the lake. The high mortality rate does not seem to frighten some species, such as the lesser flamingos. In the heat, when the water level drops further, the dead animals are left on the shores of the lake – left just as photographer Nick Brandt found them. Another factor that interferes is the temperature, the lake is in a very hot region, and its waters can reach up to 60 degrees, causing burns in the animals. The water level is naturally low, causing many birds, bats and insects – that try to cross the river, to end up falling and dying. Since the beings that die there are preserved and automatically become salt statues. Sodium carbonate was already used in mummification processes in Egypt, which gave the animals killed in the lake the reputation of mummies. This was caused by a volcano that is to the south of the lake, causing the ash runoff to run into its waters. This is due to sodium carbonate and other minerals, which end up in the lake, as a result of materials that come from the hills next to the river. The high caustic level can cause great damage, burn the skin and eyes of animals. The lake waters have an extremely alkaline pH, which is between 9 and 10.5. in salt and lasts forever”.Īccording to the American television program Discovery News, this has a scientific explanation. Just like birds colliding with glass windows, these fell into the lake.”ĭavid Harper, an ecologist at the University of Leicester who has visited Lake Natron four times, came to a conclusion in his research on the site: “If a body falls somewhere else, it decomposes very quickly, but at the lake’s edge, it gets encrusted. No one is quite sure exactly how they die, but it seems that the lake reflects light a lot and this confuses them. In the post titled All Over the Wasteland, the photographer wrote: “I unexpectedly encountered the creatures – all manner of birds and bats – along the shores of Lake Natron in northern Tanzania. The photographer and expert on the African continent, Nick Brandt, produced some images of the statues of animals that died in the lake, his work went viral on the internet and generated curiosity to understand what this lake has. But appearances can be deceiving: its waters hold a fatal secret.ĭue to the rare chemical composition, the lake ends up petrifying the animals that enter it. Lake Natron, situated in northern Tanzania, close to the Kenyan border, in the Great Rift Valley, is one of the most peaceful places in Africa.
