Delhey et al. (2019) plumage lightness data for 5,809 passerine species
Source:R/data.R
delhey5809.RdPlumage lightness measurements and environmental covariates for 5,809 passerine bird species. This dataset demonstrates environmental-covariate support in pigauto: climate variables are fully observed conditioners that improve imputation of lightness traits.
