Possible adaptations to breeding in a thermally hostile environment far inland on the Antarctic Continent includes: shorter incubation, rapid growth rate of chicks, high metabolic rate and thermal insulation in newly hatched chicks compared to other procellariiform chicks. Moreover, the foraging frequency is lower, but the chick meal size higher, than for other procellariiform bird species of similar size.
