Résumé :	This observational study of captive Caribbean Flamingos (Phoenicopterus ruber) sought to investigate the possible functions of unipedal and bipedal resting. In particular, this research sought to further examine the possibility that thermoregulation is a primary function of unipedal resting. Significant negative correlations were found between length of unipedal resting and average temperature, and between length of unipedal resting and average heat index, indicating that temperature is a major factor in determination of resting stance. A significant negative correlation was also obtained between length of unipedal resting and average wind chill, but as the observed wind chills did not significantly differ from the temperatures, such a finding is to be expected. These results suggest that flamingos rest on one leg for longer intervals in an attempt to conserve body heat. Further, a significant positive correlation between length of bipedal resting and average wind speed suggests that on windy days, a bipedal stance is preferred to enhance stability when resting.
