All the v12.1 changes will be reflected in the 2023 editions of the ATWB Companion Guides. These editions will be released commencing August 2022, after publication of the next version (v12.2) of the IOC bird list.


Some details …

Each of the ATWB 2022 Companion Guides has a number of important features, including:

– A complete taxonomic listing of bird species

– An indication of where each bird family and species can be found in its native state

– Spotlighted species that have a restricted regional or worldwide range

However, perhaps the key feature of all eBooks in the Companion Guide series is the way you can quickly and simply access relevant, up to date online information about every featured bird species. If your reading device is connected to the internet, a single click will take you to a search results page for a species, from where you can continue to search for additional information to whatever level of detail you desire.

The ‘All the World’s Birds’ series of Companion Guides derives its taxonomy, English names and scientific names from The IOC World Bird List, an open access resource maintained by the International Ornithological Congress (IOC). The IOC bird list is hosted on a dedicated World Bird Names website, which provides access to the list in various different formats.

The version of the IOC bird list used in the ‘All the World’s Birds 2022’ series of Companion Guides is Version 11.2, published July 10 2021.
