Why is gallus the element of magic if he doesn't have magic

[Flurry Heart of love 24]

why do you guys think Gallus is the element of magic? he doesn't have any magical components except for the fact he is a mixed mythical creature, but that is what most of the young 6 are. And before you say he flies, no. That's science. So type your theories in this discussion, and we will work through the logic. Thank you!
