1Y Mew Gull from Tromsø, Northern Norway

Today we had this autumns first reading of a foreign 1Y Mew Gull in the city centre of Bergen. This one was ringed by Nils Helge Lorenzen in Tromsø at Prestvannet. Nils Helge is one of the most experienced gull ringers in Norway and are together with Morten Helberg in charge of the Norwegian program for colour ringing of gulls. He informed us one week ago that we must keep our eyes open for one of his 130 ringed Mew gulls, it did not take long time before the first one appeared. J5V5 was ringed 1st of September and remained at the ringing location for three weeks. It was seen in Bergen 1207 kilometres to the south west in Norway 18 days after it was seen in Tromsø for the last time. It would be exiting to know if there are any other urban stopover sites between Bergen and Tromsø, so birders keep your eyes open for ringed Mew Gulls.

We know form earlier ringing efforts (using metal ring only) that Mew Gulls from the area around Tromsø winters in Bergen. So this was an expected observation. We will come back with a blogpost summarising where the winter population of Mews in Bergen have their origin.

J5V5 was ringed in Tromsø and was seen in the city centre of Bergen 10th of October
