Résumé :	The mass-specific activity of citrate synthase (CS) is often used as an indicator of the aerobic capacity of the pectoralis muscle. We investigated whether there is variation in CS activity within the pectoralis muscle of the Barnacle Goose. In general, no significant variation mas found except at the anterior site nearest the sternum where a significant difference was found between the peripheral and deep sites. We conclude that for comparisons of CS activity within large migratory species, samples should be taken from the uniform central area of the muscle, but for intraspecies studies on factors affecting aerobic capacity, samples should be taken from the anterior sternal site at differing depths, as this is the most variable area where adaptations to these factors may occur.
