We studied habitat selection of the woodchat Lanius senator, red-backed Lanius collurio, and masked Lanius nubicus shrikes in NE Greece, where they occur sympatrically. During the breeding season the masked shrike is most distinct, but woodchat and red-backed shrikes highly overlap in their habitat use. Multivariate discriminant analysis revealed the best separating variables from a set of 13 vegetation variables measured around perch sites. The best separating variables were identified as the woodland character for axis one, and the shrub character for axis two. By the help of the multivariate discriminant analysis the habitat selection in these avian species can be separated with high probability (64 %, 64 %, and 86 % for the woodchat, red-backed and masked shrikes, respectively).
