April 23: It turned out that there was a light blue tibia ring involved. It appeared on one of the photos too. I recently got informed that it is a bird ringed in Beltringharder Koog (Germany) on June 18, 2010. It was seen there regularly during the following summers, once with three chicks. Only two days after my observation of this bird on Rottumeroog it was noticed in Beltringharder Koog again and read there by Dominic Cimiotti for the first time this year. There were are no records of this bird during winter months. I remember seeing quite a lot of them around Aveiro, Portugal, so you could start to look for it there around that time.
