Part of my PhD research on Lesser crested tern Ecology is to use Stable isotopes SI to identify wintering range of the species in west Africa, and whether different colonies winter at one or different sites there.
I have collected some primaries from dead adult lesser crested terns breeding in Benghazi, Libya.. I wonder if somebody have done any similar studies on SI structure of other tern species wintering in west Africa, including data from both the birds and their food (mainly fish)?
Any help is appreciated
