Morphological consequences of climate change for resident birds in intact Amazonian rainforest

First, this dataset contains morphological measurements (body mass, wing length) of birds from the Biological Dynamics of Forest Fragments Project (BDFFP), located in central Amazonia. Birds were captured using mist-nets between 1979 and 2019 in the understory of primary forest spanning ~40 km. Second, we have included climate data (precipitation, temperature) associated with this study area derived from the global EU Copernicus ERA5 climate reanalysis (https://cds.climate.copernicus.eu). Methods Birds were captured in understory mist-nets within primary forest. Mass was measured either with a Pesola spring scale or an electronic balance, whereas mass was measured with an end-stop ruler. For methodological details, see https://doi.org/10.1093/condor/duaa005. Morphological measurements come in large part from bird captures analyzed for abundance trends published here: https://doi.org/10.1111/ele.13628.
