Black-headed gull (Chroicocephalus ridibundus), photographed along Akerselva in downtown Oslo, in the exact same spot as where he was ringed 7 years ago (in 2018).

He was already an adult when he received his ring, meaning at the time of this picture he's at least in his 10th calendar year, possibly older.

Since he got ringed, he's been frequently observed at the same spots along the Akerselva river. In total he's been spotted 10 times at Kuba bridge, additionally also at Nybroa, Grünerroa, Bispevika, and Anne-Cath Vestlys plass.
