--Greater Snow Geese (Chen caerulescens atlantica) may face periods of complete food deprivation during incubation in the High Arctic. We studied the ability of these birds to withstand a prolonged fast. We measured rate of mass loss, patterns of carbohydrate, lipid and protein utilization, and changes in resting metabolic rate in 11 captive geese subjected to complete food deprivation. Geese lost 44% of their initial body mass during fasting periods that ranged from 19 to 42 days (mean 34 days… CONTINUE READING
