We have Dark-eyed Juncos (Junco hyemalis) back home in California, but I don't see them all that often. This is probably because they are more of a forest bird, and the eBird reports show them to be abundant in the foothills and highlands of our local mountains. On the other hand, if one travels to the Pacific Northwest like I did this week, the forests come right down to sea level, and the Juncos are far more readily seen.
They are certainly common. Some estimates put their North American population at more than 600 million, and as many as that may be, it is just half what their population was half a century ago. We've not done a stellar job of preserving bird habitats in this country.

Dark-eyed Junco (Red-backed/Gray-headed) at Grand Canyon, North Rim
Today's bird is either the Red-backed subspecies (Junco hyemalis dorsalis), or the Gray-headed subspecies (Junco hyemalis caniceps), or both (figure that out!). It's interesting that they are all generally considered a single species, based, I assume, on DNA similarities. I've seen other bird species that were literally identical in appearance, but were not only separate species, but different genera. This kind of thing is probably the reason I became a geologist rather than a biologist!
They may be one of the most common birds in North America, but it was a privilege to see them in such a spectacular setting. The North Rim is the uncrowded side of the canyon, receiving only about 10% of the visitation in Grand Canyon National Park. It is 1,000 feet higher, and therefore cooler and greener than the south side.
