Feather deuterium as an indicator of age‐class in the Pectoral Sandpiper Calidris melanotos
We measured deuterium isotope ratios (δ D f ) in primary feathers to distinguish first‐year from older Pectoral Sandpipers Calidris melanotos captured in Barrow, Alaska, during the breeding season. δ D f showed a distinct bimodal distribution, and model‐based clustering placed the δ D f values into...
