The resting metabolic rates of Laysan albatross and Bonin petrel
chicks of known age were measured on Midway Atoll in the North Pacific
Ocean. The mass-specific metabolism peaked at hatching and then declined to
adult levels in Laysan albatross nestlings. The mass specific metabolism of
hatchling Bonin petrels was similar to that of adults, but it tripled shortly after
hatching. Fasting and feeding episodes affected day-to-day changes in petrel
chick metabolism
