[Tweeters] Dark-eyed Junco ID Question

Hank,
Here's what I've gathered about our local juncos:

Slate-colored will show no difference in shade from the crown to the nape
to the back. It'll be slate gray all the way through.
Cassiar's (which many believe is a intergrade between Oregon and
Slate-colored, although its currently considered a unique subspecies) shows
a change of color on the back compared to the nape. It's not nearly as
pronounced as the "hood" on an Oregon junco, but it's there none-the-less.
Sometimes it takes seeing the bird from different angles or with different
light sources to notice the hood line. Sometimes the back is lighter gray
than the hood, sometimes browner. Your bird shows brown on the back, so it
looks good to me for Cassiar's.
On eBird, Cassiar's Junco is called "Dark Eyed Junco (cismontanus). You
also might have the spuh option of Slate-colored/cismontanus if you don't
get enough of a look to confirm one or the other.

In Everson,
Stephen Chase
