Definitely a great way to make this book more attractive for those who want to use it in the field.
And by adding some new illustrations with every book, one can hardly get around buying it. I have only checked on the swift plate provided. Aside from some name changes due to splits, many species also come with new illustrations of the underside (e.g. Himalayan Swiftlet and most Needletails). These illustrations are not in the Thailand FG! (And I presume they are also not in any of their previously published books.)
--PS: That's a Sooty Falcon on the avatar, photo taken near Sharm el Sheik, Egypt. My highest priority raptor at the time.
What's your species on the avatar? I often have no clue!
