She furrows her brows while focusing on the claw, but her voice doesn’t sound strained when she answers you. “They generate lift in what I imagine is a similar manner, for one. The secret is in the feathers, obviously. Remiges – these wing feathers – have a couple special properties. The last segment of the wing’s core limb, the bit you strapped this claw to, the biggest feathers coming off that are the primaries. Each one can be individually positioned. Pegasi have incredible ranges of motion with them, so you’ll see them use them for non-flight purposes occasionally, like gestures, or attempting to grasp very light objects. Their motion is important with flight, and lets us do things like change the wing’s shape, increase or decrease drag at certain angles, and so on. The ones closer to my body in that same plane are secondaries, they form a lot of the wing’s lift-generating shape. Unlike the primaries, I can’t move them individually. These feathers are covered by the smaller tectrices on top that help fill out the shape and smooth airflow, which would be involved in the lift generation you mentioned.”
