  title={The physiology of hypothermia in the black-capped Chickadee,Parus atricapillus},
  author={Susan Budd Chaplin},
  journal={Journal of comparative physiology},
The shivering, body temperature, and metabolic response to stable and decreasing ambient temperature were measured in winter acclimatized Black-capped Chickadees,Parus atricapillus. Shivering activity, measured by duration and amplitude of bursts, increased curvilinearly from thermoneutral temperatures of 27°C down to 0°C. This parabolic shivering response may be a major component of the curvilinear response of metabolism to decreasing ambient temperature. Birds exposed to 0°C exhibited… CONTINUE READING
