A Brown Thrasher bounded into one of our nets this morning. This in and of itself wouldn't be unusual except that this particular bird is at least 7 years old - well shy of the 12 years, 10 months longevity record for the species, but still a significant record.
We noticed that the band was quite worn and thin but still quite readable. I took this top view photo of the old band with a new band right beside it. The aluminum has worn to almost half of its original thickness. It turns out that this bird was originally banded on May 26, 2003 as a male weighing 70.2g. The bird was encountered again on May 15, 2005 and not detected again until today when it weighed 70.2g!
