Chicks of the Manx Shearwater show a slow growth rate until an age of 8 to 10 d, after which they grow faster. This change coincide with the time at which the chicks are left unbrooded during the daytime. A high metabolic and insulatory capacity enables the chicks to maintain a stable high body temperature at an early age compared with other birds with similar nest-bound behaviour and low growth rate. This makes the chicks independent of parental brooding very early in development and enables both adult birds to forage.
