摘要:
We investigated the stable isotope signatures (δ15N and δ13C) of greater feather covers of male and female Red-backed Shrikes (Lanius collurio) of a southern German population. Male and female birds did not differ in their isotope signatures, thus revealing similar winter grounds for both sexes.
