Origins of irruptive migrations by Common Crossbills Loxia curvirostra into northwestern Europe revealed by stable isotope analysis
We used analyses of stable hydrogen isotope (δ 2 H) measurements in Common Crossbill feathers (δ 2 H f ) to infer the region of origin of Crossbills collected from different irruptions into Britain, Iceland and the Faeroes, comparing these values with those from birds sampled in breeding areas in Br...
