Understanding the Threat to East Africa’s Soda Lakes Flamingos
East Africa’s soda lakes are home to the iconic flamingos, creating a breathtaking spectacle of nature with their vibrant pink plumage. However, recent research has uncovered concerning trends that are putting these flamingos at risk. The lesser flamingos, the most numerous among the six species of flamingos worldwide, are predominantly found in the soda lakes of Kenya, Tanzania, and Ethiopia. Despite their large numbers, estimates suggest that the species is facing a decline and is officially classified as “near threatened.”
The Impact of Rising Water Levels on Flamingos
One of the primary threats to the lesser flamingos in East Africa’s soda lakes is the rising water levels. This phenomenon is particularly concerning as it directly affects the availability of their main food source, cyanobacteria. Flamingos have evolved to feed on specific species of cyanobacteria, such as spirulina, which thrive in the highly salty and alkaline conditions of soda lakes. However, as water levels rise, the dilution of the lakes reduces their salinity and alkalinity, leading to a decline in the growth of the cyanobacteria essential for the flamingos’ diet.
Research published in the journal Current Biology has highlighted the alarming fact that only half of the lakes that provided high-quality feeding habitat for flamingos in 2000 remain suitable for feeding in 2022. This decline in suitable feeding lakes directly impacts the flamingo populations, as they heavily rely on these specific habitats to sustain themselves.

Monitoring and Conservation Efforts
To assess the threats facing the lesser flamingos, researchers have utilized satellite technology to monitor 22 key feeding lakes across Ethiopia, Kenya, and Tanzania between 1999 and 2022. This large-scale monitoring effort has provided crucial insights into the changes occurring in these ecosystems and their impact on flamingo populations.
The rising water levels in lakes such as Bogoria and Nakuru in Kenya and Lake Natron in Tanzania have led to a decline in the availability of cyanobacteria, resulting in a noticeable decrease in flamingo numbers. The loss of suitable feeding habitats not only affects the flamingos but also poses a threat to other unique plant and animal species found exclusively in these soda lakes.
Protecting East Africa’s Unique Ecosystems
The challenges faced by the flamingos in East Africa’s soda lakes serve as a stark reminder of the broader impacts of climate change on inland waters worldwide. To safeguard these fragile ecosystems and their iconic pink birds, urgent action is needed. Regular monitoring of water quality and bird populations across the soda lakes is crucial to understanding the ongoing changes and identifying conservation priorities.
Efforts to protect forests near the lakes, restore degraded lake catchments, and mitigate the effects of increased rainfall are essential steps in preserving the habitats of flamingos and other unique species. By taking proactive measures to address the threats facing East Africa’s soda lakes, we can ensure that the spectacular flamboyances of flamingos continue to thrive in these remarkable ecosystems for generations to come.

Flamingos or flamingoes are a type of wading bird in the family Phoenicopteridae, which is the only extant family in the order Phoenicopteriformes. There are four flamingo species distributed throughout the Americas (including the Caribbean), and two species native to Afro-Eurasia. A group of flamingoes is called a "flamboyance".

Soda lake
A soda lake or alkaline lake is a lake on the strongly alkaline side of neutrality, typically with a pH value between 9 and 12. They are characterized by high concentrations of carbonate salts, typically sodium carbonate (and related salt complexes), giving rise to their alkalinity. In addition, many soda...

Cyanobacteria
Cyanobacteria (), also called Cyanobacteriota or Cyanophyta, are a phylum of autotrophic gram-negative bacteria that can obtain biological energy via photosynthesis. The name 'cyanobacteria' refers to their color (from Ancient Greek κύανος (kúanos) 'blue'), which similarly forms the basis of cyanobacteria's common name, blue-green algae, although they are not scientifically...
