Species and subspecies account
We followed the International Ornithological Committee v. 11.1 (Gill et
al., 2021), which considers 21 valid species and 21 conspecific
subspecies. To model the distributions of the subspecies separately, and
given the lack of more comprehensive sources, we split the occurrences
based on Gill et al. (2021), and the maps from www.xeno-canto.org (Table
1).
