The National Waterbird Census, conducted by dedicated volunteers and ornithologists, has concluded across Kenya’s iconic Rift Valley lakes, painting a picture of an ecosystem in transition. This year’s count revealed significant shifts in water levels and bird populations that underscore the dynamic nature of these critical wetlands.
Key Findings
One of the standout moments of this year’s census came at Lake Baringo, where volunteers were thrilled to record a Cotton Pygmy Goose—an Asian waterfowl first documented in Kenya only at the end of December 2025.
The news wasn’t celebratory for flamingos, however. Numbers were notably down across all major lakes where they feed, including Bogoria, Elmenteita, Nakuru and Magadi. These pink-hued flocks, once synonymous with the Rift Valley’s lakes, appeared in smaller concentrations than previous years, raising questions about food availability and habitat conditions.
On a brighter note, Palearctic migrants made a strong showing this year. Northern Shovelers, Northern Pintails, Garganeys and Black-tailed Godwits were recorded more frequently compared to last year’s census, suggesting favorable conditions along their migration routes and within Kenya’s wetlands.
Challenges in the Field
Water levels presented the most significant challenge for census teams this year. Throughout most of the Rift Valley lakes, water levels were markedly higher than in 2025, rendering large stretches of shoreline inaccessible and complicating count efforts. The elevated waters altered habitat availability and likely influenced bird distribution patterns across the region.
Lake Magadi stood as a notable exception. Contrary to the trend elsewhere in the Rift Valley, Magadi recorded very low water levels compared to previous years, with about 60% of the lake reduced to dry salt pans. This stark contrast highlights the variability within the Rift Valley’s water system.
As water levels fluctuate and species’ distributions shift, the message becomes clear: wetland conservation isn’t optional. Protecting these vital habitats ensures their resilience for both the flamingos that wade through alkaline waters and the people who call the Rift Valley home. The census continues, and so must our commitment to safeguarding these irreplaceable landscapes.
