COBirders-- We Pueblo birders have been grousing about the impossibility of identifying the individual Great Black-backed Gull(s) that has/have shown up each winter since 1993. According to Dr. Google, the oldest bird of this species on record is an individual that was banded in Massachusetts in 1968 and last seen 1994, was 26 years, 9 months old. That means that Brandon's sighting yesterday could be the same "Murray" that first came 25 years ago. However, that's not at all likely, and there's no way we will ever know.

Adult sitting on South Shore Marina tires right now. Should be here for the winter. Every winter since 1993, we have had one here!
