Correction: Using marine isoscapes to infer movements of oceanic migrants: The case of Bulwer’s petrel, Bulweria bulwerii, in the Atlantic Ocean

The Table 3 caption incorrectly appears as the fifth paragraph of the Results section. Please see the complete, correct Table 3 and Table 3 caption here. The publisher apologizes for the error.

Correct classification rates (%) obtained using stable isotope analysis (δ¹⁵N and δ¹³C values) for P1, S8 and R6 of Bulwer’s petrel tracked with geolocation, and validation of the discriminant analyses using the testing data. Discriminant functions obtained using δ¹⁵N and δ¹³C values of S8 and R6 to infer the non-breeding areas of Bulwer’s petrel. For each feather, the higher result (for the Central or South Atlantic) indicates the belonging of the bird to that cluster.
