Fig. 4. Example of oxygen measurements during song by a starling in the large respirometry chamber. The rise in the rate of oxygen consumption (O2) (central panel) is slow after the onset of song (indicated as oscillogram in the bottom panel). A segment of song (grey horizontal bar) is also shown spectrographically (top panel).
