Fig. 7From: Multi-isotope (δ2H, δ13C, δ15N) feather profiles and morphometrics inform patterns of migratory connectivity in three species of North American swallowsBiplots with 40% Bayesian ellipses showing feather isotopic overlap in δ13C–δ2H, δ13C–δ15N, and δ15N–δ2H for adult swallows from breeding populations in Saskatchewan (A–C), Ontario (D–F) and Yukon (G–I). Feather isotope values represent non-breeding ground (winter) molt locations. Barn Swallows reliably showed the highest isotopic values consistent with the most terrestrial diet. Increasing distance between ellipses indicates greater isotopic dissimilarityBack to article page
