Abstract
Historical variations (1966e2016) in the exposure to inorganic elements in raptors of South West Spain
have been little studied. Therefore, uncertainty exists concerning whether environmental or anthropo genic inputs, as well as dietary strategy shift, may cause changes in exposure patterns. To address this
gap, essential and non-essential inorganic elements were measured in Common kestrel (Falco tinnun culus) feathers from museum specimens and free-living individuals spanning a 50-year period. Moreover,
stable isotopes of d13C and d15N were also measured as proxies of Common kestrel feeding ecology over
time. In general, all elements showed significant increasing trends overtime, suggesting changes of in puts from local sources. Moreover, d15N signatures were correlated to the variations in Al, Cr, Cu, Fe, K, Li,
Mg, Mn, Ni, P, Pb, Rb, Sr, Ti, V and Zn concentrations, suggesting trophic changes in this kestrel popu lation as well as possible biomagnification processes. Finally, some values of Cr, Mn and Pb were above
the threshold concentrations of potential toxicity.
