My talk is Flapping Birds and Space Telescopes.

Two pigeons are flapping out they've spotted a kestrel.

What does that mean for the origin of flapping flight?

It's this flapping birds, toys, cootie catchers, that sort of thing.

And this is you can see this is a flapping bird.

And here he is, flapping with his ears and very gracefully going up.

They fly, not with rotating components, so they fly only by flapping their wings.

I'd return to the darkness, where I'd join my bizarre companions. (High pitch buzz) (Flapping noises)

We're working on projects now even wing flapping things the size of hawk moths DARPA contracts, working with Caltech, UCLA.

He's making a, kind of, cheek flapping sound. Well, suffice it to say it's not all like that, but that's part of it.

She stopped about 10 feet away from me, and she sat there with this penguin, the penguin's flapping, and she let's it go.

Did they not see the birds above them, stretching out, and flapping their wings. No one keeps them up in the sky except the Beneficent God. He certainly watches over all things.

So we looked at the birds, and we tried to make a model that is powerful, ultralight, and it must have excellent aerodynamic qualities that would fly by its own and only by flapping its wings.

The one final bit of sparkle we'll put in at the very end here is an utterly impractical flight vehicle, which is a little ornithopter wing flapping device that rubber band powered that we'll show you.

When they asked him if he knew much about photography, he lied, learned to read Europe like a map, upside down, from the height of a fighter plane, camera snapping, eyelids flapping, the darkest darks and brightest brights.

like hand flapping, rocking back and forth, or aggression, and in some institutions, psychiatric drugs are used to control the behavior of these children, whilst in others, children are tied up to prevent them from harming themselves or others.

But attached to the base of the wing is a set of little, tiny control muscles that are not very powerful at all, but they're very fast, and they're able to reconfigure the hinge of the wing on a stroke by stroke basis, and this is what enables the fly to change its wing and generate the changes in aerodynamic forces which change its flight trajectory.

The shirt sleeve planted a shrewd blow in Hall's face that stopped his open armed advance, and sent him backward into old Toothsome the sexton, and in another moment the garment was lifted up and became convulsed and vacantly flapping about the arms, even as a shirt that is being thrust over a man's head.
