Avitaxonomicon is a private website that intends to put together up-to-date scientific information on the systematics of birds. Individual families are treated to genus level (except most Passeriformes).

The project started in 2016, driven by my fascination for birds (and science). Over the years, I realised that today’s taxonomy is still incomplete, lacking a specification how to assign categorical ranks to taxa, including species. I consider the application of temporal thresholds the only universal way to address this task. A first step towards a solution to the rank-allocation issue is suggested under “Plea for chronotaxonomics”.
