Oregon and Slate-colored Juncos together

At this time of the year there are always lots of Dark-eyed Juncos in my neighborhood, as in most of lowland western Oregon, and almost 100% of them are the "Oregon" form. But occasionally a "Slate-colored" shows up, and today in my own back yard it happened. The "Oregons" didn't exactly welcome him to the table, but he managed to get his share around the edges.
