[Tweeters] Towhee diagnostics and a weird whitish West Seattle warbler

Trileigh,

The towhees that sometimes come to western Washington from eastern WA or farther north are also distinguishable because they have much larger white tail spots than our resident subspecies oregonus, about two times as long. The spots on the upperparts on oregonus vary a moderate amount, so the tail spots should be checked as well to be certain you have a migrant from elsewhere. I think your most-spotted one is probably still within the range of oregonus. The two subspecies that are possible here (not maculatus) are curtatus from eastern WA and arcticus from still farther east and north, both of which are dramatically spotted.

Ahh, if tweeters could only allow attachments, maybe a maximum of one per message . . . I know, I know, it would get out of hand anyway.

The most common around here is oregonus, which is much less spotted than maculatus. (Unhelpfully, maculatus is also officially part of the name of the whole species.)

From the photos posted on this helpful link<https://wildfidalgo.blogspot.com/2011/03/spot-check.html> provided by a fellow Tweeter, I can see that maculatus indeed is at the far end of spottedness. Without the comments I received in response to the post below, I sure would have assumed they were all the same species with just random variability in spottedness.

I assume it’s simply an unusually white Yellow-rumped Warbler—it has just a tiny hint of yellowing under the wing—but if you have other ideas, I’d be interested. (That photo<https://www.flickr.com/photos/trileigh/33554037822/in/dateposted/>’s also on my Flickr page.)
