CJBS2003 is correct, except now there is just one species of junco called the dark-eyed junco. There use to be 5 or 6 different species and the slate was one of them but then "they" just combined them to one species.
The birds are noticeable because of their dark eyes and pink bill and are in the sparrow family.
They sit on my dock and swoop out over the water then back to the dock. They are gone now, headed north.
