Very interesting article. It starts out by stating:
"A new study offers the first hard evidence that birds use feathers for audible
communication as well as for flight and warmth."
The editors may have used their poetic license here, as proof of use of
feathers for audible communication has been available for many years. Local
examples include the drumming of a ruffed grouse, the booming of a nighthawk,
the courtship flight of a woodcock, and the courtship flight of a snipe..
This story on manakins is, however, fascinating because of the different manner
in which sound is generated - by using wing muscles to rapidly vibrate
individual feathers, rather than vibrations induced by air passing modified
feathers as in nighthawks, woodcock, and snipe.

Our Mourning Dove makes a good bit of racket with its wing feathers, but it
isn't very musical,IMHO.
