The presence of brown on the back of a 'Slate-colored' Junco suggests an
intergrade origin, Junco hyemalis X oreganus, rather than a flat-out
hyemalis, which should be solid slate. As with hybrid (or intergrade, if
some of us have our evil way '-) gulls, where there's a stable
hybrid/intergrade zone, there's usually a continuum of characteristics from
one parent type to the other.

Yep. They're on their way.
