molotl.

MOLO-TL, House Finch (Haemorhous mexicanus) [FC: 48 Molotl]: “It is chalky, ashen, dark ashen; short-billed; medium sized, small; agile, a hopper; a singer. It is a warbler, a talker. It is capable of domestication; it is teachable; it can be bred.… The completely ashen one is the hen, and the chili-red-headed one is the cock…. It sings constantly. It hops about, it hops almost constantly. It is agile; it moves with agility.” Certainly, the House Finch. The male may be distinguished as CUACHICHIL/NŌCH-TŌTŌ-TL.
