The West Indian hummingbird, Eulampis jugularis, maintained its body temperature in torpor at 18� to 20�C over an ambient temperature range of 2.5� to 18�C. At ambient below 18�C oxygen consumption during torpor increased linearly with decreasing temperature. Thermal conductances were the same for resting and torpid Eulampis regulating their body temperatures at 40� and 18�C, respectively.
