Energy costs assigned to behaviors for time-energy budget of two captive Whooping Cranes.

Energy costs are reported as a multiple of basal metabolic rate (BMR). aSleeping with head drooping or resting on back. bResting but not sleeping. cFood capture, manipulation, and consumption behaviors. dValues in [37] reported as multiples of resting metabolic rate. Estimated xBMR value of rest-alert for Whooping Cranes used to convert this value to a multiple of BMR. e Similar to value estimated in [23] for pacing Whooping Cranes. fPreening, stretching, bill flicking, head shaking, and head rubbing. Energy costs assigned to behaviors for time-energy budget of two captive Whooping Cranes.
