A subset of ~650 passerine species from Delhey et al. (2019), with
plumage lightness measurements and climate variables. Covers species
from the same families as avonet_subset that have plumage data.
Note that species names use underscores (e.g.,
"Corvus_corax"), making this useful for demonstrating name
normalisation.
Format
A data frame with columns:
- TipLabel
Species name with underscores (tree tip label format)
- family
Family name
- annual_mean_temperature
Annual mean temperature at range centroid
- annual_precipitation
Annual precipitation at range centroid
- lightness_male
Mean plumage lightness, males
- lightness_female
