Supplementary Material for Stable isotope analysis reveals dietary and foraging ecology in Neotropical birds

This supplementary material provides additional analyses related to the article Stable isotope analysis reveals dietary and foraging ecology in Neotropical birds. It includes complementary information on species-level variation that helps to contextualize and expand upon the results presented in the main manuscript. The file includes mean isotopic values for sampled species (δ¹³C and δ¹⁵N), Bayesian regression outputs, pairwise comparisons across dietary guilds and foraging strata, and maps of sampling sites.
