The understanding of bird species and how they are grouped into families has changed rapidly since the introduction of DNA analysis. So much so that it is difficult to keep up with all the newly identified species and revisions to interrelationships of families.

The aim of the All the World’s Birds series of eBooks is to help birders and bird lovers gain a better appreciation of these changes. Together these eBooks will provide a Companion Guide to all the world’s bird species. With the exception of the Part-by-Part series, ATWB eBooks are published on Amazon as Kindle eBooks.

ATWB Online enables you to browse the content of ATWB guides. To access the ATWB Online portal click here. Be sure to read the INTRODUCTION to ATWB Online before browsing for the first time. It explains how the content that is presented online differs in its FUNCTIONALITY from a Kindle eBook.

Starting April 1st 2026, any title in the COUNTRY GUIDES and INTERACTIVE CHECKLISTS series of eBooks may be ordered free-of-charge for delivery to your Kindle reading device. To learn more click here.

 

In June 2025 the first version of The Global Avian Checklist (AviList) was released. All eBooks in the series of ‘All the World’s Birds’ Companion Guides are now being modified to use the AviList as the primary source of information about taxonomy, English names and scientific names. Previously, the World Bird List published by the International Ornithological Congress (IOC) was the basis for the content of these eBooks.

The AviList is updated once a year.

The version of the AviList that is used in 2026 editions of ATWB eBooks is v2025, published June 11 2025.
