In many bird species, egg membranes can be obtained non‐invasively after the chicks have hatched, and stable isotope analysis of egg membranes can be used to study the diet and foraging distribution of these birds during egg formation. It has been suggested that the enrichment factors of albumen and egg membranes differ for13C, but are similar for15N. In this study, we compared carbon and nitrogen stable isotopes of the membranes and albumen of individual eggs of three wild seabird species, the Southern Rockhopper penguinEudypteschrysocome, the Imperial shagPhalacrocoraxatricepsalbiventer, and the Thin‐billed prionPachyptilabelcheri. We also included chicken eggs for comparison. Egg membranes were generally enriched in13C, compared with albumen. The difference varied between species, with 2.1‰ in Rockhopper penguins, 1.6‰ in Imperial shags, but only 0.5‰ in Thin‐billed prions and 0.4‰ in chicken eggs. Egg membranes were slightly enriched in15N in Imperial shags (0.9‰) and chickens (0.5‰), compared with albumen, while there was no difference for Thin‐billed prions and Rockhopper penguins. The isotopic values of carbon and nitrogen were correlated between albumen and egg membranes of individual eggs, suggesting that egg membranes can be used reliably to investigate trophic differences between individuals, seasons or colonies. Species‐specific mathematical corrections could be used to compare results across studies that use different egg components. Copyright © 2009 John Wiley & Sons, Ltd.
