Absolutely incredible - there is so much we don't know about the natural world it's ridiculous. Thanks for bringing this to my (and NPNers) attention.

Nighthawks make a thrumming sound when they dive. I've been told it is made by their breast feathers.

That is very interesting, Cheryl..thanks!
Buck...I think you're right about the Nighthawk. I've only seen and heard it one summer and it was awesome to listen to it as it was swooping through the sky!

Amazing video. We tried to watch them in Tobago recently but they were not easy to watch.
Snipe make a sound with their tail feathers when diving during mating, it sounds like helicopter blades to me. I've heard it many times here in Colorado, usually at dusk.
