1. 1.|Oxygen consumption () and body temperture (Tb) of Hawaiian brown noddies (Anous stolidus pileatus [Aves: Laridae]) during late incubation and in the first 24 h after hatching were measured at ambient temperatures (Ta) between 28 and 38[deg]C and between 15 and 43[deg]C, respectively. Evaporative cooling by hatchings at Ta of 36-43[deg]C was also measured.2. 2.|Throughout the late incubation stages studied, and Tb both varied directly with Ta in an ectothermic pattern.3. 3.|The hatchlings successfully regulated Tb at Ta between ca. 29 and 43[deg]C.4. 4.|The functional basis of the abrupt increase in thermoregulatory capacity with hatching is discussed.
