Mimicking Bird Songs

Each bird species has its own unique sound and song, and for centuries human hunters have been devising whistles or perfecting their own whistling techniques to mimic the calls of birds. But until recently, this art was not fool proof. Now, using a rubber tube, physicists have been able to create device that imitates bird calls and, when played back, is almost the exact reproduction of the original bird call. Their simple device has proven to be a breakthrough in the mimicking of bird calls and songs, and is still being researched as they wish to improve on their device.
