The use of measurements of naturally occurring stable isotopes of the light elements C, N, H,
O, S in avian tissues and their associated foodwebs has grown tremendously during the last …

Stable isotopes in metabolically inert tissues of migratory animals can be used to infer
migratory and dispersal histories. The general approach for estimating geographic origins of …

Despite recent advances in technology, it remains difficult to connect breeding and non‐
breeding areas of populations of migratory organisms due to the challenges of year‐round …

In North America, gradients in the ratio of stable hydrogen isotopes in amount-weighted,
growing-season mean precipitation (2H: 1H; depicted as δ2Hp) form a largely latitude …

Understanding bird migration and dispersal is important to inform full life-cycle conservation
planning. Stable hydrogen isotope ratios from feathers (δ 2Hf) can be linked to amount …

Vagrant birds are mesmerizing birdwatchers worldwide, but the nature of vagrancy and the
true origin of the vagrants are poorly known. To Western Europe, the massive Siberian land …

Hydrogen stable isotope ratios of keratin (δ2HK) are increasingly used as endogenous
markers to study animal movements, yet it is unclear what factors might influence δ2HK in …

Analyses of the stable isotope composition of feathers can provide significant insight into the
spatial structure of bird migration. We collected feathers from Great Reed Warblers …

Understanding turnover rates of stable isotopes in metabolically active tissues is critical for
making spatial connections for migratory birds because samples provide information about …

The application of stable-hydrogen isotope (δD) measurements to the study of animal
movement, resource use and physiology depends on understanding factors driving variation …
