Energy expenditure and food requirement of Cassin's Auklets provisioning nestlings
We used the doubly-labeled water technique to measure the field metabolic rate (FMR) of free-ranging adult Cassin's Auklets (Ptychoramphus aleuticus) that were provisioning half-grown nestlings. FMR averaged 3.68 +/- 0.38 mL CO2 g-1 hr-1 (n = 9), which is equivalent to a daily energy expenditur...

Summary: | We used the doubly-labeled water technique to measure the field metabolic rate (FMR) of free-ranging adult Cassin's Auklets (Ptychoramphus aleuticus) that were provisioning half-grown nestlings. FMR averaged 3.68 +/- 0.38 mL CO2 g-1 hr-1 (n = 9), which is equivalent to a daily energy expenditure of 413 +/- 59 kJ. |
