Steller's were seen in Gambell last week, he may not have updated. He could also photograph Steller's Eider while on St Paul Island, and Spectacled Eider when he goes to Barrow for Ross's Gull. He got Gray-headed Chickadee in November 2016 outside of Kotzebue, Alaska so I wouldn't be surprised if he tries that spot again.
If I have got this right, Stellers was available at Gambell and Nome and Spectacled on Gambel whilst John was around, but no evidence he connected. No records of either on St Pauls this fall are on eBird.
I noticed from Joe's spreadsheet, that no one on a big year has connected with the Chickadee since 2016, and John was the only one that year. In addition it made me look at the other code 3 that this relates to, but only where they are resident. It appears that these are all in Hawaii, including Laysan Duck, Millerbird, Laysan Finch, Nihoa Finch - are these off limits?
