Continuing bird at this location, bulkier than adjacent HERG, dark scapulars, thick all black bill, smudgy eye. Head oddly dusky but "probably just dirty because structurally looks good for GBBG", per Clinton. Reported by Mike H earlier this week.

Edit: I sent this bird to MN Gull experts Mike Hendrickson, Clinton Dexter-Nienhaus, and Ezra Hosch; who all independently concured that this was a 1st cycle GBBG.
