Tremendous job and wonderful tool. Well organized, concise, clear. It should greatly increase interest in identifying these different subspecific groups locally and thereby adding to our knowledge of abundance, seasonality, and distribution.
And in completing this guide you've made the rest of us look like stereotypical slackers.
Well done on both accounts.

Monumental and very helpful
Central Oregon is a great area to utilize this information. Some of our subspecies seem to come over from the west, while others seem to come over from the interior. I also think there is some variability as you move north and south along the east slope of the cascades.

Subject: [obol] Oregon Subspecific Groups Guide
I have been working on learning the eBird taxonomy and how it groups common species in Oregon with subspecies and the like. I made a guide for myself, that I decided might be helpful for others so I spruced it up some and wanted to share it out.
I looked closely at 29 species of common Oregon birds with multiple regularly occurring subspecies or subspecific groups in the eBird taxonomy (try guessing which ones). There are photos from eBird, links to maps, and other miscellaneous stuff folks might find interesting.
I have learned a ton about these extra puzzles in our state, I hope you might too. There are still quite a few mysteries especially in Central Oregon where group overlap is unclear, and other places too.
To be clear, this relies a lot on how eBird organizes subspecific groups and is probably most useful for people who frequently use eBird. But it should be helpful and interesting to others who use eBird less or not at all.
If you notice mistakes or edits and would like to share with me, please do so.
