Norwegian Hawfinch update

Dave reminds me that I hadn't posted the details of our 2nd Norwegian Hawfinch recovery! The bird, an adult male, was ringed at our main feeding site near Dolgellau on 22nd March 2014. It was controlled by a Norwegian ringer at Batteriveien nord, Lyngdal, Vest-Agder on 13th April 2015, 387 days after original ringing and 905 kms distant. It will be very interesting to see if we can get a "bounce" and retrap him back in Wales this winter.


The Red markers show the two recovery locations (most recent bird on the left) and the Green marker shows the original ringing location of the Norwegian-ringed control. The Blue marker is the main feeding site.

The map above clearly indicates that there are regular movements occurring between South Norway and Wales and therefore what we might once have regarded as a resident population is obviously augmented by continental visitors in the winter months.
