Sandwich terns of Texel island have fledged

This Dutch video is about ringing young Sandwich terns in Utopia nature reserve on Texel island.

Some have flown to the Wagejot nesting colony not far away. In the Slufter nature reserve near the North Sea, some twenty young terns ringed in Utopia have been seen. There, they meet young Sandwich terns from elsewhere, like Griend island and Goeree.

Black walnut, from North America to Texel island?

On 30 June 2015, Ms Sytske Dijksen of Ecomare museum found a nut on the beach of De Hors, in the south of Texel island in the Netherlands.

The nut turned out to be a eastern black walnut. Probably, the Gulf Stream had brought it all the way from Florida or elsewhere in eastern North America to Texel. These nuts drift well.

There are a few eastern black walnut trees in parks in Europe, but the nuts on beaches there probably have all made long trans-Atlantic journeys.

In 1995, for the first time an eastern black walnut was found on a Dutch beach; also on Texel. Since then, it was found a few scores of times in the Netherlands. They have been found in France and England as well.

More about research about Sandwich terns, ringed on Texel, is here.

Ever since 2012, 70 Sandwich terns have been seen on Texel which had been ringed in the south-west of the Netherlands. 16 birds had been ringed in the north-east of Scotland. Other terns (four individuals or less) came from Belgium, Griend island, Ameland island, Sweden, Portugal, Spain, Italy, or the Gambia.

In 2014, 88 young Sandwich terns were ringed at the nesting colony at Utopia nature reserve. Some have been seen again in England and France. Most one-year-old Sandwich terns spend their first summer in Africa, returning to Europe later. In 2015, more young Utopia terns were ringed.

A video about ringing these Texel Sandwich terns is here.
