I recently read "Birdscapes; Birds in Our Imagination and Experience" by Jeremy Mynott. Published by Princeton University Press, who provided me with the well-made, hardcover book for this review. It comes in at 367 pages, 66 of which are appendices and notes about the main text. The font is fairly small, but diagrams and illustrations break up the text.
Including references from mythology to modern culture, the main thrust of the book addresses how & why we think the way we do about birds in numerous contexts, from their appearance and attitude to the sound of their songs.
It was an interesting read, but may be somewhat confusing to non-birders. Written by an Englishman, he references birds like robins--but English robins are nothing like the robins we know in the U.S. He also tends to use "birder-speak" that may be common across the pond, but is definitely not the language used by your typical, American birder.
Despite the potential for some confustion, it was a well-thought out book, written in an easy, conversational style and would certainly be a nice gift for any naturalists or birders on your list.
