Today was a very good day for Common Gulls: large groups in the city (this is uncommon for Amsterdam) and an ice floor to facilitate ring reading. Additional to the birds shown I also read two Finnish birds.

The Iceland Gull is still present. Today it was accompanied by two Caspian Gulls, one of which was ringed in Poland!

Present already on Saturday at the same location as the other two Caspians (not when I was there though...) but I only had the time to photograph it today. Another Polish bird, ring numbers only differ by 16!
