Table 2. Assignment of individual feather stable isotope value to four isotopic clusters based on δ²H, δ¹³C and δ¹⁵N (according to [21]) and the percentage of raster cells assigned to four isotopic clusters within the individual 50% KDE and 75% KDE.

Grey shading indicates corresponding assignment of individual feather stable isotopes and KDE.
