Wolf, Nathan (2023), Wyoming hummingbird breath d13C, Dryad, Dataset,


Here, we present data from two experiments conducted n the Rocky Mountains of Wyoming, USA to assess the relative use of feeder and flower nectar by Broad-tailed and Rufous hummingbirds using two distinct methods to measure the δ13C values of exhaled CO2 – manual sample collection (2010) and automated analysis (2018).
