[[So, male Tengus have larger beaks, or is Sagiri's just smaller? Again, loving what you're doing... Can't wait for the next chapter!]]

Reponse:

Um, that’s a good question. Actual ravens have zero sexual dimorphism (differences between males and females) and the female tengu in this story totally lack any typical ‘feminine’ traits (no breasts since who the hell would want to breastfeed something with a beak). I’m considering giving them smaller beaks just so there is some physical clue of their gender without resorting to some Minnie Mouse hair bow and eyelash shortcuts.

So, tl;dr yes females have smaller beaks.
