I like this very much. I like Cyrus as a name for the gryphon, I love their interaction and dialogue (and yes, they definitely have very distinctive voices, esp. the gryphon, and a distinctive conversaton style), and some of the lines are just great. Such as when Cyrus is reluctantly admitting that Oasis's "coloring is regular, her forehead is at a good angle, and she is strong." That was truly wonderful.

If I may offer a critique, though, the line where Siyamak is praising the gryphon and being like "cheer up, you're terrific, you'll have a mate no problem"...the line is a little awkward and sounds out of voice for him. It sounds kind of fake to me. It especially sticks out because the rest sounds so natural.

So I assume this is relatively earlier on in the story?
