The animals probably aren't truly calcified, but are coated with sodium carbonate or sodium bicarbonate, said Cerling, who has researched the chemistry of Africa's Rift Valley lakes. So he believes the birds and bats were confused by the sky's reflection in the lake and killed when they hit the water. However, Brandt said that many people in the region have seen birds crash-land into the water.
Since there are few predators in the area, their bodies remain and become salt-encrusted when the lake's water level drops. Thure Cerling, professor of geology and geophysics at the University of Utah, said by email that the animals in Brandt's photographs likely died of natural causes. Lake Natron's unusually harsh composition comes from a unique neighboring volcano, Ol Doinyo, which spews alkali-rich natrocarbonatites that end up in Lake Natron via rainwater runoff.

Pink flamingos can be spotted in other places around Tanzania such as the Momella lakes, at Lake Manyara, Lake Magadi around the Ngorongoro Crater and other alkaline lakes in the northern parts of the country.A "calcified" swallow sings in stony silence along northern Tanzania's Lake Natron (map), which contains so much soda and salt that it would "strip the ink of my Kodak film boxes in a few seconds," according to photographer Nick Brandt.Brandt unexpectedly found the dead animals that had washed up on the shore, preserved by the lake, and posed them as they had been in life. When the chicks are strong enough, a few adults escort them to the fresh water by foot. The sight of around 100,000 chicks protected by their parents is truly amazing. They eat their egg's shell and then are fed by their parents for a few months. Small grey chicks usually hatch between December-February. A single egg is laid and incubated by both parents for 28 days.
It's impressive to see how a pair of flamingoes builds a nest, which can be up to 30 cm high to protect the chicks from the floods and to keep it cool. If you want to see the egg laying and hatching, the best season starts with the receding of the water level, October and December is the peak. Over 75% of the world's population of flamingoes are born in the Lake Natron, as this is the only place where the eggs are regularly laid.
