Jumping spiders use their legs to communicate courtship interests to potential mates. The minuscule impacts of spider legs tapping against the ground surface are detected by nearby spiders. This "drumming" cadence signals the spider's reproductive interests. The female detects the low frequency vibrations through her legs. She responds by allowing the male to mount her.
Absolutely amazing video here. The sound is the best part, so make sure it's on.

Manakins (
Manacus sp.) are small, colorful sparrow-sized birds found all over Central and South America. Manakin males engage in
elaborate courtship dances, including rhythmic sounds they produce with their wings. No one really knew how the birds made this sounds, until
Kimberly Bostwick, Curator of Birds and Mammals at the
Cornell University
Museum of Vertebrates, went into the jungles of Ecuador to film the birds at 1000 frames per second. As it turns out, different species of manakin use entirely different motion to produce the sounds. The Journal of Experimental Biology has
published the results, complete with
videos.
Mark Barres, who studies avian genetic population structures at the Univ. of Wisconsin, has also filmed
the mating dance of the Manakins [.mov].
