Using δ 2 H stable isotope analysis to identify the origin of a first winter Red-breasted Goose Branta ruficollis caught in Norway
We analysed hydrogen stable isotopes (δ 2 H) in first generation median wing covert feathers sampled from a free-flying first winter Red-breasted Goose Branta ruficollis caught at Storøya, Norway in late April 2019. Highly depleted δ 2 H values corresponded to those predicted if these feathers were...
