This was my mistake as I saw a book with birds and a famous name on it and expected it to be about birds. But instead it was about a particular stay of Audubon in Louisiana where he got a lot of bird material for his later bird guide. It describes the property, family and circumstances of that Summer, guided by other sources and some speculation. There's very little about birding or birds, until the end where a number of Audubon's illustrations are presented. As I had no real interest in the character, I didn't find it very interesting.
