Birds Migration Influenced by Climate Change

Climate change affects the behavior of traveling birds: geese, ducks and swans spend their winters in wetlands of northern Europe changes its habits of migration as temperatures rise.

British experts say, because many of the birds no longer migrate north to the south of the continent, the number of specimens of species once common as winter guests is now declining in the UK.

Researchers at the University of Helsinki conducted a study based on data provided by the Observatory of birds in Hanko, Finland. Here, since 1979, several volunteers have followed the birds daily, making a “census migration”.

Following investigations it was found that during the migration of birds traveling has changed. They move to new territories with a delay of nearly a month, compared with 30 years ago.
Six of the 15 species that migrate researchers have followed a month later now than they did at baseline.

Experts say that water temperature has increased more than the air, which means there is more food. Therefore, waterfowl have no reason not to migrate over long distances.

That is now the UK has become one of the last winter destinations of waterfowl, which spend their winter here, coming from northern regions – Scandinavia, Siberia and European Russia.

Scientists say that in the past 10 years, the number of copies of large backwater (Anser albifrons) in England fell by 75%.

Moreover, if 30 years ago at Slimbridge, 6,000 birds winter came, only 500 are now back.
