The Tana Delta Restorers: How Local Communities are Helping to Sustain Ancient Migration Routes

By Milka Musyoki

As the first light of dawn breaks across the Tana Delta, Omar Ngama quietly adjusts his binoculars. This local community birder has witnessed something encouraging over the past few years: early signs that bird numbers, including migratory species, may be starting to recover along this stretch of Kenya’s coast.

“Yesterday, I saw some Yellow Wagtails in the restored grasslands,” Ngama recalls, his voice filled with cautious optimism. “We’re also seeing more Eurasian Bee-eaters during migration seasons. We cannot say for certain, but it seems the birds may be responding to our restoration work.”

Ngama is one of several community members monitoring sites across the Delta, tracking what appears to be the early stages of recovery at one of Kenya’s most important migratory bird stopover sites. Their careful observations are revealing an encouraging story of revival for both resident birds and the thousands of migratory species that depend on this ecosystem.

Ancient highways in the sky

Every year, millions of birds embark on epic journeys between their breeding grounds in Europe and Asia and their wintering areas in Africa. For centuries, the Tana Delta has served as a crucial rest stop along these ancient flight paths, where exhausted travellers find food, water and shelter before continuing their marathon journeys.

The Delta’s unique mix of wetlands, forests, woodlands and grasslands creates perfect stopover conditions for different species. Its grasslands provide crucial foraging areas for migrating birds like Yellow Wagtails, Eurasian Bee-eaters and various birds of prey, whilst wetlands teem with terns, sandpipers, plovers and other wading birds.

“Think of it like a service station on a very long motorway,” explains Paul Gacheru, Species and Sites Conservation Manager at Nature Kenya. “Migratory birds fly for thousands of kilometres and still have thousands more to go. Without places like the Tana Delta, many wouldn’t survive the journey.”

The Tana Delta is just one critical link in a vast network of stopover sites stretching from the Arctic to southern Africa. Recognised as both a Key Biodiversity Area and a Ramsar site (a wetland of international importance), the Delta’s global significance is well established. But habitat loss poses one of the greatest threats these ancient avian travellers face. The destruction of wetlands, forests and grasslands for agriculture, development or infrastructure can be devastating. A single critical stopover site lost can break the chain of migration.

The stopover degraded

The Delta faced mounting threats: proposed major developments, uncoordinated governance, resource over-exploitation, poor land use practices, encroachment, unsustainable agriculture, resource conflicts, diminishing water supplies and climate change. These combined pressures degraded the key habitats that birds and other wildlife depended upon, causing once-vibrant flocks to dwindle.

A solution came through developing a participatory land use plan, completed in 2015, to guide policy and decision-making. In 2019, the Tana Restoration Initiative (TRI) project, funded by the Global Environment Facility through the United Nations Environment Programme and implemented by Nature Kenya, began supporting community-driven restoration efforts.

Instead of dictating solutions, the project asked communities what they needed and how their traditional knowledge could guide restoration efforts.

Ngama was among the first volunteers to join his village’s Natural Resource and Land Use Committee. “I grew up seeing birds, but I never understood how important our Delta was to birds from so far away,” he says. “Learning about their migration patterns changed everything. These aren’t just ‘our’ birds – we’re caring for birds that belong to the whole world.”

The restoration work focuses on habitat improvements benefiting communities, migratory birds and the Delta’s broader wildlife. Communities now collect tree and grass seeds, then plant them in degraded landscapes using methods passed down through generations.

“We know what grows well in our landscapes, and when to plant for the best success. The TRI project enhanced the indigenous knowledge we already had,” says Namkuu Dara, a community leader from Ozi.

To date, a total of 10,467 hectares of degraded landscapes, including grasslands and forests, have been restored. 

The feathered travellers’ return

While it’s early to gauge the full impact of restoration activities on migratory bird numbers, Ngama remains optimistic. As he packs away his binoculars after another morning of monitoring, he reflects on what the gradual return of migrants might mean.

“These visiting birds have been making their journeys for thousands of years,” Ngama concludes. “If our restoration work helps even some of them continue making it for thousands more, we’re part of something much bigger than just our Delta.”

The Tana Delta’s story demonstrates how local communities can become vital links in a global conservation network. The real success lies not just in returning bird numbers, but in communities understanding their role as custodians of one crucial stop along these ancient highways in the sky.

KBA in Focus: Kwenia

By Joshua Sese

Situated in the centre of Kajiado County’s semi-arid landscape, Kwenia Key Biodiversity Area harbours remarkable biodiversity across its cliffs, plains, and seasonal wetlands. Its soaring cliffs offer vital breeding grounds for vultures, including the endangered Rüppell’s Vulture, while Lake Kwenia and the surrounding savannahs support abundant birdlife and wildlife.

Kwenia faces conservation challenges that threaten its fragile ecosystems and globally significant vulture colonies. The most urgent issue is vulture poisoning, which occurs both intentionally as retaliation against predators and unintentionally through poisoned livestock carcasses left in the landscape. Habitat degradation from expanding livestock grazing, agriculture, and settlements is encroaching on grasslands and seasonal wetlands, reducing habitat quality for birds and other wildlife.

Human-wildlife conflict drives these pressures, while climate variability and extended droughts impact seasonal Lake Kwenia, reducing its ability to sustain migratory birds. These threats are intensified by the site’s lack of formal legal protection and limited conservation resources, making the area susceptible to unregulated land-use change.

But the story of Kwenia isn’t one of inevitable decline. Conservation is already taking root through a partnership between Maasai landowners, the Kenya Bird of Prey Trust, and conservation groups. A proposed 12,600-hectare Vulture Sanctuary now protects the cliffs and seasonal lake, with long-term monitoring confirming over 200 breeding Rüppell’s Vultures alongside other species like the Egyptian Vulture.

Community volunteers actively monitor vulture nests and raise awareness about the dangers of poisoning, while landowners have signed a Sanctuary Trust deed to secure the site’s future. These actions blend science and community stewardship, laying a strong foundation for protecting one of East Africa’s last great vulture strongholds.

Without stronger protection, awareness, and coordinated conservation efforts, Kwenia’s ecological and cultural values remain at risk. But with continued community leadership and support, this remarkable landscape can thrive as both a vulture sanctuary and a model for community-led conservation.

The Yellow-billed Storks of Dunga Swamp

By Hezbone Okoth

If you’ve ever visited Dunga Swamp on the shores of Lake Victoria, you’ve probably noticed them: elegant Yellow-billed Storks stepping carefully through the shallows on their impossibly long legs. With their distinctive yellow beaks and patient demeanour, they’re hard to miss. But there’s much more to these birds than meets the eye.

Walk down to Dunga Beach any morning and you’ll see fishmongers busy preparing their catch for market. Fish scales glint in the early sunlight as they expertly fillet their haul, tossing intestines and other scraps onto the shore. It might look like a messy business, but watch closely and you’ll spot something fascinating happening.

Almost as if on cue, the Yellow-billed Storks arrive. They swoop down with surprising grace, making quick work of the fish scraps. You might think they’re just opportunistic scavengers grabbing an easy meal, and you wouldn’t be wrong. But they’re also doing something remarkable: they’re acting as nature’s cleanup crew.

Without these feathered cleaners, all that organic waste would pile up, rot in the sun and create a pretty unpleasant situation for everyone. Instead, the storks turn potential pollution into their breakfast, keeping the shoreline clean and the surrounding ecosystem healthy. It’s a win-win situation that nobody planned, but everyone benefits from.

Masters of the shallows

But don’t think these storks just sit around waiting for handouts from fishmongers. Spend some time watching them hunt, and you’ll see they’re incredibly skilled predators. They wade through the shallows with their bills slightly parted, like a trap waiting to snap shut on unsuspecting fish, frogs or aquatic insects.

The local fishermen consider their presence good luck. When Yellow-billed Storks are around, it usually means the water is clean and fish are plentiful. “If we see many storks, we know it will be a good day for fishing,” one fisherman told me. It’s a simple observation that speaks to something profound about how the presence of birds indicates healthy ecosystems.

Next time you’re at Dunga Swamp, take a moment to watch these remarkable birds. They remind us that in nature, nothing happens in isolation. The fishermen, the storks, the water, the fish – they’re all part of an intricate web where everyone has a role to play. And sometimes, the most important work happens so quietly you might miss it if you’re not paying attention.
