What's the function of this part of a feather?

Sorry this feather is a little messy looking. It dropped on the ground and then got swept and then messed with so I hope you can still see what I'm trying to show.

I have always been curious about that jagged little edge that sticks out on the side towards the end. I believe only one feather on each wing has that. Does anyone know the reason for it? Does it help in flight or something?

I’m not sure it has a function. Might be a little generic quirk. Jasper doesn’t have them and Gilbert only has a few feathers that do it. On Gilbert it’s not jagged, but rounded and smooth.

Wow, really? That's interesting! I thought all birds (or atleast Quakers) had atleast one

Well where is the feather from, wing? Looks like a flight. What kind of bird do you have?

P6 looks like it. And given where it's located I'm sure it has a function. I'd have to research though, which I'm a science nerd, so I'd love to!

If you do research I'd love to hear your thoughts! My guess would be that the "hook" (that's a great term for it Keri!) Catches on to the next primary feather to eliminate gaps when flying. Just my guess

Feather hook dude
That looks exactly like Blu's before I ruffled it up! :)

It's not just one feather either, 2 or 3 on each side, and the other flight feathers have a smaller hook on the top side and not the bottom.

Oh, cool! I don't think Blu has that many! Maybe he does but I've never seen them and I don't feel comfortable spreading his wings to get a better look

The "Guide to the Quaker Parrot" by Mattie Sue Athan says, "ornithologists call this unusual feather shape 'notching' or 'emargination'. These feathers facilitate slow flight, maneuverability, hovering, and backward flight." Other species that have this feature are senegal parrots, red fronted macaws, and male princess parrots.
