This is a rare species for Texel.
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.
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.
This video is called Cumanotus beaumonti nudibranch.
This is a video about a small copper butterfly in the Netherlands. This individual has the normal colours for that species.
On 22 May 2015, in the Krimbos woodland on Texel island, local people Henk Leyen and Klaas de Jong saw this butterfly. Mr de Jong made the photo. It is a leucistic small copper; looking much whiter than usually.
This 29 June 2014 video from Texel island in the Netherlands is providing 100 young Sandwich terns at Utopia nature reserve with colour rings for research.
Nature reserve Utopia
Since May 2015 there is a webcam in the Utopia area. The webcam is in the middle of the colony of Sandwich terns.
Through this webcam, you can also enjoy these beautiful birds while you are at home. Through this webcam also the behaviour and especially the food supply of these Sandwich terns is monitored. This is done by researchers of Imares.
Latest news from the Sandwich tern colony
May 19, 2015: This morning Imares researchers put 10 small bowls in the colony. These bowls are among the many nests and in this way, the researchers hope to catch the droppings of the Sandwich terns. The dung is then collected weekly and analyzed. This way they can deduce from the dung which food remains there are still in it, so what the terns have eaten. Through visual observations (including via the webcam) it is seen that they bring different types of fish. But the terns also eat while on their way, flying, and that often remains invisible. So we know that they catch from the sea swimming worms and eat them, hopefully this is also confirmed by the investigation of the poo.
