Winging it.One South American rain-forest bird is quite the ventriloquist--"singing" with its mouth closed. Now, scientists have found that the club-winged manakin's trick is in its wings, which flap at 106 beats per second. Kimberly Bostwick, an ornithologist (bird scientist) at Cornell University in New York New York, state, United States New York, Middle Atlantic state of the United States. It is bordered by Vermont, Massachusetts, Connecticut, and the Atlantic Ocean (E), New Jersey and Pennsylvania (S), Lakes Erie and Ontario and the Canadian province of , studied manakins by using a slow-motion video camera. She discovered how the manakin manakin (măn`əkən), common name for stocky, tiny birds, most measuring less than 5 in. (12.5 cm) long, comprising 59 species in the family Pipridae. makes its "tick-tick-ting" tune without moving its mouth.

"These wing sounds can easily travel up to 50 meters (164 feet) through the rain forest," says Bostwick. That's good news for male manakins, which rely on their violinlike songs to attract a mate. |
