This morning on the way to work, I saw for the second time this week a Buteo hawk perched on a light pole in the median of SR-520, about .25-.5 mile west of the 148th Ave NE exit in Redmond, that had a field mark I'm not used to seeing on a Red-tailed Hawk.
It's hard to look at a bird and also drive in traffic at 60mph, but both times I saw what appeared to be a large conspicuous red patch on the bird's shoulder. I didn't get any more field marks either time.
