Ian Paulsen (who often has the inside track on field guides) posted the following information on his facebook page which should be of interest:
"Penguin/Random House has announced the publication date for the newly revised Nat Geo East/West Bird Guides: 4 February 2025. The 8th edition of the whole guide is due out in September 2025. Normally this would have been done in reverse order, but given that Disney now owns Nat Geo Publishing, it must be part of their marketing plan?? Plus from the sample pages I have seen of this new version, it’s been Disneyfied (with apologies to Ted Floyd)! So it’s no longer an advanced bird guide but for upper level beginners/ lower level intermediate birders. I'm disappointed by this because this is the bird guide I lost my "birding virginity" to. The first edition was published in 1983, the year I graduated high school and entered college. I learned so much from this guide and took it everywhere I birded. I became a much more experienced birder because of this guide.
