Fig. 6

Whole blood δ15N versus δ13C values of Blue petrels (blue squares), Thin-billed prions (red triangles) and Antarctic prions (black circles) from Kerguelen Islands during the inter-breeding and early breeding periods. Isotopic values of feathers that were moulted during the inter-breeding period were corrected to allow an accurate comparison with blood values (see text). Arrows indicate the isotopic shifts from the inter-breeding to the early breeding period. Values are means ± SD
