I remember in a previous picture of Aya he said he was unsure how to draw her ears, so he had her hair cover them. That's probably why he explained their shape this time.
But wouldn't that much hair create a lot of wind drag?
I know, I know, Gensokyou physics
My personal theory has always been that tengu manipulate inertia somehow. Of course, Aya herself can control wind, so drag is probably irrelevant to her.

There's nothing stopping her from manipulating the wind around her so that won't happen
