BWB comes in at 326 pages, with a large and airy font. This means that the book is not particularly word heavy. The author was out in the field every day, no breaks, and (spoiler alert) recorded 6,042 species. It is reasonable to understand that this means that there are more days spent in the field than there are pages in the book, and that if the species were all to get a mention in the narrative then there would need to be an average of 18.5 species per page. What the author has decided to do is use 51 pages as a complete list appendix, a blow-by-blow account of what, where and when. On first seeing this I felt a bit cheated that one sixth of the book was taken up in this way, but when reading the narrative it quickly becomes apparent that, because of the editorial choices, it was the only way that a reader could have a firm handle of what happened.
There are some bizarre choices made. Sri Lanka, Thailand, Malaysia, Borneo and Indonesia are covered - altogether - in just one paragraph! The whole lot!! That's 397 species swept under the carpet. Madagascar and Kenya are dismissed in a sentence!!! At the same time he spends three pages describing a stopover in Germany when he went and saw a feral population of Egyptian Geese. There are several other imbalances, but some of these are touching interludes or frank confessions as to why he is doing what he is doing. These gave an emotional edge to the book, a connection with the author beyond him being a robotic birder. The book really needed to be twice as long. Had it been, it could have been a classic.
TBT (300 pages) is far more of a 'went there, saw that' account, denser in narrative but maybe missing the more cerebral aspects of such an enterprise (if, indeed, the authors believed there was one). For a birding adventure, this book wins in my opinion, even if it - possibly - lacks Strycker's depth. They are both worth your while, and both underlined to me that, even though I would dearly love to have travelled more during my life, I would be useless on such an escapade. I would be fretting and worrying at every turn about logistics, safety, the weather, etc, etc. You cannot possibly commit such an adventure to a smallish book. Both have tried in differing ways to get across what happened and what was seen. As to which is the more successful depends on what you want from such a book - why they did it, or what they saw. To cover both aspects needs more pages - many more pages.
