Bird Flu Outbreak Spreads Across West African Migratory Route

Bird Flu Outbreak Spreads Across West African Migratory Route

An avian influenza outbreak has been detected in the West African nations of Senegal and The Gambia.

Caused by the highly pathogenic H5N1 bird flu, conservationists working in the area are now worried that without more funding to contain the  it will spread further among the millions of birds that move through the region as they migrate between southern Africa and northern Europe.

Already, reports from Senegal suggest that at least 1,552 dead wild birds have been found, while in The Gambia at least 500 dead seabirds have been recorded at Tanji Bird Reserve. The birds found dead have reportedly included great white pelicans, great cormorants, gray-headed gulls, royal terns and the West African crested tern.

In addition to this, hundreds of cases of bird flu have been found in poultry, which has led to the culling of tens of thousands of chickens.

Teams of conservationists in Senegal and The Gambia have been trying to tackle the  in a bid to contain its spread. Their efforts have included collecting as many dead wild birds as possible and burying them. But there is a fear that because the wetlands and coastal marshes where the infected birds have been found are on migratory routes, it might lead to further outbreaks in Europe.

Sacha Dench is the founder of the charity Conservation Without Borders who have been working to contain the outbreak in The Gambia. She told the Guardian, "It's migration season, so these outbreaks threaten birds and poultry all the way from Africa to Europe and the UK."

"Rapid reaction is critical. So having staff on the ground with the resources that enable them to act is essential. Investing in monitoring activities in developing countries would save a lot of birds we love, and could save [the poultry farming] industry a lot of money."

What is the East Atlantic Flyway?

The East Atlantic Flyway is one of eight major migratory routes used by birds, such as waders and shorebirds, to move around the world between breeding and wintering grounds.

It connects northern Europe both to North America in the east but also to the warmer climes of Africa to the south, with the southern route tracing the Atlantic coastline of Africa from Morocco all the way down to South Africa. It is estimated that some 90 million birds use the flyway going in both directions.
