Wild geese change routes to cope with climate change

Barnacle geese are choosing new feeding sites to cope with climate change, according to Scottish researchers.

A team from St Andrews University, along with Norwegian, Dutch and British colleagues, found that the birds were flying further north in the Arctic. The findings are based on 45 years of observations by experts.

The teams found that the migratory birds, which traditionally fuelled up, or staged, just South of the Arctic circle in Norway now mainly staged in northern Norway far above the Arctic circle.

Dr Thomas Oudman of the school of biology at St Andrews, said: "It makes sense that the birds went even further north, because where snow used to be very common there at the time of their arrival in Norway, these days it is often freshly green there: the most nutritious stage.

Barnacle geese are able to adapt to climate change due to the availability of alternative places with sufficient food at the right time, and without the threat of disturbance from humans or other dangerous animals.
