Physicists Look at Birdsong


Image hosting by Photobucket

"With spring on the way, physicists have turned their attention to the familiar sound of birdsong and have developed a mathematical model to explain the breathing patterns of canaries when they sing. By treating both a bird's vocal organ and neurones as nonlinear systems, researchers have found that complex songs, involving notes of many frequencies and lengths, might be produced by surprisingly simple neurological structures and processes. The results could shed light on how birds learn to sing and even how humans learn to speak -- a process thought to be similar to the mimicking behaviour of baby birds (Phys. Rev. Lett. 96 058103)."
