An Oldie, but a Goodie...

Given the numbers I found present (157) last Saturday at highish-tide during the Brent Goose Census, I decided to revisit Mill Bay this evening, on the County Down side of Carlingford Lough, on a lower tide.
Amongst the 116 birds counted today, there were three ringed birds, and one of these was special - ISYY. ISYY, with its cross-banded I, which I ensured we replaced for future ringing with a straight I (because of possible confusion with T), was one of the project's very first catch, at the Wexford Slobs, on 13 February 2001, and has been a regular visitor there over the years. I see that I last recorded it on 18 April 2013 on Annagassan Beach, Dundalk Bay, County Louth on 18 April, 2013. Ringed as an adult, this bird is now 14+ years old. The rewards of long-term monitoring!!...
