2014-09-26: With the second volume of Howard and Moore 4th edition due very shortly, I have been working on mapping the revised taxonomy into Avibase. I was very happy to be a major contributor in the production of both volumes and look forward to continue playing a role in keeping the list up to date in the future. With more than 10 years elapsed since the publication of the 3rd, one would clearly expect this to be a major update, particularly given the speed at which our understanding of bird taxonomy is currently changing. I can already say that changes have been affecting more than half of all taxa (species and subspecies) in one way or another, and this is not accounting for changes to citations (authors and year of publication), something that Dickinson and his team have been painstakingly examining. The H&M4 version should be integrated within Avibase within a few weeks, but I encourage you to order a copy of the 2 volumes if you have any interest in bird taxonomy. In addition to the list of name itself, the book includes detailed range descriptions for all species and subspecies, accurate citation information, and thoroughly detailed footnotes with thousands of references.
