Analysis of stable isotopes in feathers of Red-backed Shrikes ( Lanius collurio ): no evidence for different wintering habitats of males and females

Red-backed Shrike (Lanius collurio) Science Article 6

abstract

We investigated the stable isotope signatures (d15N and d13C) 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
