Which lake in Tanzania is a major breeding site for lesser flamingos?

The Tanzanian lake that is a major breeding site for lesser flamingos is Lake Natron. This shallow, highly alkaline lake lies in northern Tanzania and is one of the most important breeding places for the species in East Africa.

Lake Natron's harsh chemistry helps protect flamingo nests. High salinity, hot water, and caustic conditions make the lake difficult for many predators and other animals to enter. Lesser flamingos feed around soda lakes on cyanobacteria and other microscopic organisms, and they build mud nests on exposed or seasonally forming islands.

The lake is not the only place where lesser flamingos can breed. Other breeding sites include Etosha Pan, Makgadikgadi Pan, and Kamfers Dam, while Lake Natron is especially important because it is the species' principal regular breeding area in East Africa. Flooding can sometimes make the lake unsuitable, causing birds to use alternative sites.

Lake Natron's importance also creates conservation concerns. The lesser flamingo is classified as Near Threatened, and changes in water levels, pollution, disturbance, and proposed industrial development can affect its limited breeding habitats.
