„Avitaxonomicon“

Avitaxonomicon is a private website that intends to put together up-to-date systematic 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. 

Over the years, I became convinced that today's taxonomy is still incomplete, lacking a specification how to assign categorial ranks (incl. species rank) to taxa. I consider the application of temporal thresholds to be the only logical and universal way to delimit categorial ranks. The rank-allocation issue is treated on the page “(Chrono-) Taxonomics”.
