„Avitaxonomicon“

Avitaxonomicon is a private website that intends to put together up-to-date taxonomic information on birds from order to genus level. The exceedingly speciose perching birds (Passeriformes), however, will be treated to family level only. The project started in 2016, driven by my fascination for birds.
