From Russia with KF87

Today (31st of October) we found the first ever Herring Gull with a Russian color ring in the city centre of Bergen. It was a 1Y gull and when giving it bread we were able to get quite close and get some nice shots. However, due to daylight saving it's almost dark here at 60 degrees north around four o'clock which may show in the pictures. The bird is probably a new arrival of the day, because this weekend we spent many hours both on Saturday and Sunday ringing Herring Gulls in urban Bergen without seeing this white Russian. We do not know where it's ringed yet, but a sms to Morten Helberg who also have read Russian Herring gulls said that it's almost certain ringed in Kandalaksha in the inner part of Kandalaksha Gulf in the White Sea around 600 km south of Murmansk. The distance travelled is the largest distance we have recorded of a Herring Gull found or ringed in Bergen, 1513 km, but this may change when getting the correct ringing data.

KF87 in Bergen. Note that all scapulars are juvenile and not moulted. Other Herrings in Bergen have at least started renewing the scapulars and mantle feathers. Malling Olsen and Larsson (2003) describe this delayed moult in birds with northern origin. Just to compare see the picture below of a Herring Gull where most scapulars are moulted.

JN617 have as most Herrings in Bergen this time of year moulted the majority of scapulars
