Independently, I was told upon inquiry (when I found I could no longer get to Birds of North America) by Seattle Public Library that it had discontinued its subscription this year due to low usage by patrons. I don't think King County Library System ever had it.
Birds of the World is available by subscription, though I doubt Seattle Public would go for it soon, given the above. However, if you are a major ebird user, which I think in this case means at least 1,000 checklists submitted in 2019, you get a free year's subscription (same user name and password). Who knows how that will look in the future? A little digging around makes me think they want to pretend this never happened, and we shouldn't expect to see that again.
Power to Sno-Isle Libraries for being better. Let me know if you find the above has been improved. (I want a way to keep getting at it next year.)
And no Ash-throated Flycatcher in Seattle again this afternoon at the Fill (where photographed and reported this morning). Maybe it's a different individual, as so many eyes were looking unsuccessfully there the last two days.
