Do swans herald snow for the UK?

13 10 2015

There has been some speculation that the UK may be in for a cold winter after the arrival of a migrating Bewick’s swan from Russia.

The swan arrived at the WWT Slimbridge Wetland Centre in Gloucestershire on Sunday 11 October, the earliest date since records began at the site in 1963. It is thought low temperatures, snowfall and north easterly winds in Russia have encouraged Bewick’s swans to start their westwards migration through Europe early this year. The swans have also been spotted gathering on lakes in the Netherlands.

WWT studies have shown that the weather is a major influence on when Bewick’s swans migrate from Russia, with the wind direction being a particularly crucial factor.

Unusually cold weather has developed over a large part of continental Europe and is likely to persist through this week with temperatures around 5-10 degrees below average. Daytime temperatures in Russia on Monday were around 3-4C which is more like the average nightime temperature for this time of year. The cold weather is extending further west and south going as far south as the Mediterranean coast of France and north east Spain.Eur Coldwave 131015 Snow has fallen over southern Poland, western Ukraine and eastern Slovakia.

WWT’s Julia Newth said:
“Apparently there’s a Russian saying ‘the swan brings snow on its bill’, because they tend to move just ahead of the cold weather. Of course, we can’t infer much from the arrival of a single swan but it’s certainly exciting this bird has arrived so early.
“It’s only a year old and, because it’s made it all the way here on its own, we assume that it must have come to Slimbridge last year as a cygnet with its parents. We record all the Bewick’s swans that come to Slimbridge each winter by their unique bill pattern as part of our study and give them a name. This one needed a name, so we’ve called him Record Breaker.”

The public can see the Bewick’s swans at WWT Slimbridge where they are fed daily from November 1 to the end of February. They can also be seen via the webcam.

Will the cold weather in Europe affect the UK?
High pressure is currently dominating the weather over the UK with winds from the east bringing cold air. Many places will stay dry with bright days and chilly nights with temperatures around, or a little below, average for the time of year. However, there will be some showers, especially along eastern coasts and in the southeast of England over the next few days.
