Appears to be a hybrid of Junco hyemalis with a Zonotrichia sparrow such as White-throated or White-crowned. Note the pale eyering, larger overall size, blocky head shape, oversized bill, larger eye relative to the (blocky) head, striped mantle and Zonotrichia-like pattern to the tertials and secondaries.

Calystegia macrostegia ssp. amplissima is a perennial herb that is native to California and is endemic (limited) to California.
It is included in the CNPS Inventory of Rare and Endangered Plants on list 4.3 (limited distribution).

I reviewed the ~dozen taxa present in Cochise COunty and bigelovii is the only one that appears to match this specimen, mostly due to the leaf structure. From Kearney & Peebles:
"FNA notes that B. bigelovii is distinguished by its short stature, obovate, coarsely and irregularly serrate leaves, erose-ciliate phyllaries and 5-nerved cypselae. Similar to B. thesioides, which differs having narrower, more oblong leaves with more evenly serrate margins and spinulose teeth."
