[cobirds] Banding Rosy-finches in Colorado - We have a neat listserv

COBirders--  On New Year’s Day at 5:00 p.m. I posted a query about a banded Rosy-finch photographed the day before on the Westcliffe CBC in Custer County.  I asked if anyone knew of records of Rosy-finch banding in our state.  Several COBirders responded right away, with two reminding me of a Dec. 12 post to COBirds asking for help in collecting data about Rosy-finches for CPW.  About two hours later I received an email from Aaron Yappert, the author of the December post for help.  Later he contacted other participants in the Westcliffe CBC and yesterday at 2:00 p.m. he told us that, “…as far as I can tell, the band on the left leg is entirely silver. We put colored bands on the left leg and unfortunately, our black bands fade to silver within a year or so.  A solid silver band, likely originally a black band, indicates that this bird was banded on a Mesa about 15 driving miles WNW of Telluride, CO, sometime between January and April of 2018.” 

Thank you, COBirders!!
