XOCHI-TŌTŌ-TL, literally, “flower bird,” Black-backed Oriole (Icterus abeillei) [FC: 45 Xochitototl] “Its throat, breast, [and] belly are yellow: flower-like, well textured. It has a face-band. Its head, back, wings, [and] tail are [black] mingled with white, in wavy line. Its legs are black.” This is certainly the Black-backed Oriole, now considered a species distinct from the Bullock’s Oriole (Icterus bullockii) of Martin del Campo’s list.
