Subject: [obol] Oregon Subspecific Groups Guide
Hi all,

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.

You can find it here on my Google Drive

Good birding,
