a personal name that has some relationship to the Roseate Spoonbill bird(?) (SW)
Ironically, the hieroglyphic or logosyllabic images of people with this name (or Quecholomi) emphasize the bird or its feathers rather than anything about bones. So, perhaps the -omitl suffix has another explanation. See these examples from the Visual Lexicon of Aztec Hieroglyphs, ed. Stephanie Wood (Eugene, Ore.: Wired Humanities, 2020-present):

In contrast, the Codex Vergara spells out the name Quecholomi or Quecholomitl phonetically, with no semantic indication about the meaning of the name:
