To view this video please enable JavaScript, and consider upgrading to a web browser that supports HTML5 video Caption This is a high-speed video of syringeal kinematics during sound production in the domestic pigeon. The first part of the video is imaged under incident lighting, followed by trans-illumination, which clearly reveals the inner contours of lateral vibratory mass (LVM) motion. Recorded at 4000 frames s-1 and slowed 133 times. The extracted LVM inner contours were superimposed upon the individual images (right, green; left, red).
