Spotted a Mute Swan at Killingworth with an unusual Green Ring with white NFL. I immediately turned to my supplier of all Bird Knowledge and 48hrs later I received the following information
from Alan J:
Green darvics are put on by Allan Brown who rings swans in the Edinburgh area. NFL has been seen at Killingworth in recent years but it covers more ground than that:
Ringed as a cygnet 14/8/2011 at Queen Margaret University Pond, Edinburgh
Recorded at Killingworth 27/8/2012 by A Rickheard.
Back at St Margaret's Loch, Edinburgh 17/2/13.
Now back at Killingworth.
