·     EB.p187.pdfp192.#3: ’u-su > us “vulture” giving as reference COL LC Vase.

·     Zender-TMMD.p5.c1.l-10 describes the Late Classic cylindrical vase shown in Zender-TMMD.p5.fig1.r2 (probably the same as EB’s reference). The iconography depicts three “anthropomorphized” animals – a dog, an opossum, and a vulture (recognizable from the distinctive hook at the end of its beak). Each has tagging glyphs, respectively: OOK.ki, u.chu, and u.su. From the last animal, we get us = “vulture”.

·     It’s unclear to me whether it’s just a shorter form of usiij, or a different word.
