Notably, flamingos are adapted to drink water that approaches the boiling point. This is because some of them live in areas with high salt concentration, with the only source of fresh water being the boiling geysers. Flamingos can also tolerate extremely salty and alkaline water.

Kimaru said flamingos start returning to Lake Bogoria from mid-June, adding that, up to October the lake usually hosts thousands of flamingos, turning it into a pink lake. It is also the peak season for international tourists.

"Most of our tourists to Lake Bogoria are from China, representing 30 percent of our visitors. They are mainly interested in flamingos," he said, adding that the flamingos are also a key attraction to many other international tourists.

Besides the dazzling display of flamingos, the lake features bubbling geysers and hot water volcanic springs erupting along the banks and within the lake itself. They are the main attractions during the seasons when flamingos migrate for breeding.
