On page 70 there is a picture of a Kenku's head but, the words are unreadable. I can make out what looks like the word soft but, I can't read anything else.
What does it say?
It is pretty much just pointing out anatomical features and fairly well gives the artistic impression of the aged drawings of our own world. The words aren't really as important as the "feel" the art lends (that you are looking into the very being of the Kenku).
But, since are curious I will make out what I can. I will start with the upper left hand side and move clockwise... no promises on accuracy and I can't make it all out.
1. Upper Jaw?
2. Hard Palate (The hard palate is a thin horizontal
bony plate of the skull, located in the roof of the mouth.)
3. Soft Palate (the soft part of the oral cavity, located posterior to the hard palate.)
4. Illegible
5. Trachea
6. Esophagus
7. Illegible
8. Epiglottis (flap of tissue that covers the glottis to keep food from entering the trachea.)
9. Tongue
10. Lower Jaw?
Anyway, those are my interpretations.
