Movies S1 and S2

Movie s1
Heat dumping to the bill during entry into sleep. Thermal imaging video demonstrating transient movement of body heat to the bill during initiation of sleep in a toco toucan. Time-lapsed data obtained at 10-s intervals. Total frames = 724, total length = 2 hours.

Movie s2
Sleep-state transitions witnessed as changes in bill temperature. Thermal imaging video of transient changes in bill temperature that occur during sleep while the bill is tucked between the wings. Time-lapsed data obtained at 10-s intervals. Total frames = 724, total length = 2.7 hours.
