Bird lovers in for a treat as migrants flock Rift Valley

As the winter season slowly approaches in Europe, bird enthusiasts are in for a treat as migratory birds start arriving in the Rift Valley.

Conservationists say this season’s migration has started earlier than usual much to the delight of bird watchers and nature lovers.

Twice a year, millions of birds fly hundreds and even thousands of kilometres across continents in search of food and the perfect grounds to breed and raise their young ones.

Lake Bogoria National Reserve senior warden James Kimaru said eight species of migrants have been spotted in the past two weeks during the latest water-bird count.

The birds include the Madagasgar pond-heron, African skimmer, the ruff, common sandpiper, wood sandpiper, and common greenshank.

Mr Kimaru said there were an estimated one million greater flamingos in Lake Bogoria while lesser flamingos numbered fewer than 2,000. Another group of birds called little grebe were a little over 1,000.

These birds are among dozens of species expected to grace major wetlands in the country in a phenomenon expected to last through to December.

Enthusiasts have taken to an online forum known as Spring Alive, which is a platform that brings together residents of several counties as they track and document the various birds sighted.

Spring Alive began as a European project and was extended to Africa in 2010, where from September onwards enthusiasts look out for the return of bird species from their breeding grounds in Europe and Asia.

This helps to create a real-time map of the incredible journeys these birds take every year.

Enthusiasts, experts, and tourists are expected to pitch camp at the Tugumoi Ridge flyway, which forms part of the African-Eurasian flyway circuit, to watch as raptors and storks glide over the Rift skies to Egypt and other African countries.

A flyway is a flight path used by large numbers of birds while migrating between their breeding grounds and their wintering grounds. Flyways generally span continents and often pass over oceans.

“It is often an interesting time when bird watchers come together to witness the spectacle unfold on some set dates. A live feed linking several countries is usually key in updating visitors on the exact dates to expect the spectacle in certain points,” Kimaru said.

Nature Kenya communication officer John Mwacharo said this season’s Afro-Eurasian migration came earlier than expected with several regions across the country recording sightings in the just concluded water-bird counts.

“Water-bird counts are usually conducted during January and July/August just after the migration. This month, we have started receiving recordings which we are updating in Spring Alive where citizens record birds they have spotted to allow for data analysis and tracking,” Mr Mwacharo said.

A peek into Spring Alive under the Kenyan category reveals several sightings of white storks spotted in Rift Valley, Eurasian bee-eaters spotted in Mount Kenya and barn swallows spotted in parts of northern Kenya.

The birds make the journey despite the growing environmental pressures arising from deforestation and pollution.

On October 12, bird lovers celebrated World Migratory Bird Day whose theme this year was “Protect Birds: Be the Solution to Plastic Pollution!” The event highlighted the impact of plastic pollution on migratory birds and their habitats.
