I'm perplexed by the statement about a convex bib -- I assume as opposed to
a concave bib. I lived in Virginia for 60 years, & all our Juncos were
Slate-colored. I don't recall a distinct bib, just a generally grey body
except for the white ventral side(yes, there's subtle shading in the grey
areas, but hardly a distinct bib). and the line of white was concave to
the belly. Oregon Juncos, on the other hand, have a distinct bib, which is
convex to the belly (ergo, concave to the head). perhaps someone could
clarify, maybe with a picture?
