I've been lurking for quite some time and have finally decided to post when I read that someone saw a possible ZTHA at Neah Bay, WA. This seems highly unlikely given their typical range isn't really any further north than Arizona. If anyone can contact the original people who sighted this bird I would like to ask if they considered the possibility that this is far more likely to be a dark morph Harlan's red-tailed hawk than a ZTHA? Any pictures would be great! If this really is a ZTHA, I would consider making the drive from Portland to look for it.
