| Research Abstract |
In this study I developed the method to measure energy expenditure with each behavior of wild bird using by the combination of doubly labeled water (DLW) method and bio-logging. I validated DLW method to compare the respirometric method in rhinoceros auklets and streaked shearwaters. When applying DLW method to wild birds, long measurement periods and high metabolic rates were eliminated sufficient isotopes from body of wild bird. This sufficient elimination of isotopes enabled to increase the precisions of DLW method. There was a positive correlation between energy expenditure and acceleration of each individual activity levels in experiment of swimming duck on pools. I measured energy expenditure of flying shearwater by the combination of DLW method and bio-logging, which detected bird behavior, such as flying, resting on seawater, and so on. Flying shearwater expended 2.9 times larger energy than when they were resting.
