Cuahuitl (MH513r)
This compound glyph for the personal name Cuahuitl covers its bases. It includes, on the left, a tree (cuahuitl) trunk, and on the right there is an eagle's (cuauhtli) head in profile facing toward the right. The tree trunk, which has stubs from branches that have been removed, is painted yellow. The eagle's head is white (like a bald eagle) with a yellow beak. Its beak is slightly open.

The combining form for both nouns, tree and eagle, is the same: cuauh-, although, as Gordon Whittaker (2021, 90) points out, the vowel length is different, with cuauh- for tree/wood and cuāuh- for eagle. So, these are near homophones in the stem form. In this case, the gloss says Cuahuitl, which would easily be represented by a glyph of a tree or some wood. But perhaps the artist was concerned that the reader might read it as ocotl (torch pine) or some other tree. So, he added the eagle to ensure a phonetic reading that would start cuauh-. If so, then the eagle is a phonetic complement which helps ensure the correct reading.
Why a Nahua man would have a name relating to tree or wood may have something to do with the significance of the metaphor, in tetl in cuahuitl (the stone, the wood), which the friars (such as Sahagún, Book 6) described as having an association with knowing secret things.

Erik Velásquez García (2019, 77) discusses KwAW-KwAW (without identifying if it is this example in particular) as a logogram-homophone in the manner of a rebus.
