Color banded Herring Gull

[Charles Duncan]

Today at Mill Creek Cove (next to Hannaford) in South Portland, I saw an immature Herring Gull with an orange band marked CYN on the lower left leg.  The lower right leg had a USGS metal band.  The bird wasn't close and my photo is barely, I mean BARELY, legible but the band was easily read through a scope.  

My eBird checklist with two photos of the gull is here: https://ebird.org/me/checklist/S107204731

Anyone know the back story on this bird--where and when banded and by whom?

Charles, thanks for reporting your resight of CYN.  I banded her/him as a chick on 7/6/21 on the roof-top of the Portland Art Museum.  The museum is home to the largest roof-top nesting Herring Gull colony in Portland, fledging ~100 chicks per summer.  Yours is the first resight of this individual bird.  If you are interested in hearing more about this project and what we have learned, I am giving a virtual talk on 4/27 for the Portland Library: https://www.portlandlibrary.com/events/sustainability-series-herring-gulls/.
