For the last ten years, so far September 2017 has had the lowest numbers of Vaux’s Swifts at Wagner and Selleck, good numbers at JBLM, record highs in Chehalis and Rainier, OR. No Vaux’s detected in Bend and La Grande, but a record pace in Roseburg. I’m guessing the fires are playing a part in this but am not smart enough to figure it out.

Is the ash having a profound impact and are younger birds surviving? Do we have empirical evidence to support the ash fallout does affect migration or it doesn't? I think it's an interesting topic of research.
