Thanks compilers for all your work, and thanks everyone who has contributed.
This update, coming at the end of October and as Fall Migration has pretty much wrapped up, is a relatively stable point to check in - only a few late migrants and then winter birds left for the year lists.
Here’s how things look compared with recent years:
We’ve tallied 390 species statewide as of the end of October in 2025. That’s one higher (essentially the same) as we had at this point last year and the year before.
For Western WA, our 361 total is 1 lower than last year, and 4 lower than 2023.
For Eastern WA, our 319 total is 4 lower than last year, and 5 lower than 2023.
Overall, we’re looking pretty similar to last year.
Looking at the percentage of each county’s total list seen, 33 counties have seen between 60% and 75% of their county’s total list - a pretty consistent result saying about 2/3 of the birds on any county’s have been found The biggest outlier: Okanogan County, which has seen 81.6% of its list total already this year.
34 counties have totals within 10 of their 2024 totals.
18 counties have higher totals than this time last year, while 17 have lower totals than at this point last year.
Four counties have exactly the same total as at this point last year [Asotin, Pierce, San Juan and Walla Walla].
91 species have been seen in all 39 counties, and 168 species have been found in 30 or more counties.
If you'd like to take a look at where things stand, the list and many other interesting files are at the Washington Birder website:
