From Aber to ABBA?

Have just received an email from Peter Olsson, the ringer who is researching the rare race of Baltic Dunlin, one of which we caught near Llanrhystud on 16th April 2013. Apparently he was observed singing at Tygelsjö ängar back on his Swedish breeding grounds yesterday, just 5km from where he was ringed as a chick! 

The capture in Wales was very unexpected and Peter speculates that it may have been following Scottish or Icelandic birds on its first spring migration. It is amazing to have been able to contribute to their research.
