This book was a tough one. I already knew about a number of these birds and their importance, so it wasn't a ton of new stuff, but I also learned a lot of interesting facts and was kinda of walloped, honestly, but the Cormorant chapter. I could not honestly guess why that bird mattered that much, but I actually really liked his argument. I was also intrigued by his argument for the Sparrow and the Penguin's inclusion. I learned some interesting history and saw some of these birds in a different way, as representations of ideas. So in that way, a good book.
But I had a lot of issues with this book, too.
1) It is very clearly a book with an imperial bias. A lot of the history and literary and mythology references were limited to the Western world, specifically the UK and America. He mentioned that there were some myths in other cultures about, say, Ravens, but only ever went into detail about the Western ones. I was actually cussing out loud when he basically said, in the Dodo chapter, that since the Maori fro New Zealand, in their explorations, killed birds for sustenance as they explored, indigenous people aren't as "harmonious" with nature as the world thinks. I was so pissed to read that. This white, imperialist dude trying to say that indigenous people don't deserve their reputation for respect for nature as a sort of slimy defense of all the disrespectful, gluttonous, destruction of the natural world by the Western world for centuries. Fuck. Off. I almost put the book down right there. He also used the terms "New World" for America and "Old World" for Europe, which are outdated and biased as well. Small things like those added up to an extreme distaste for the bias.
Weirdly, however, the author did a great job centering the suffering of 80,000 Chinese men who were essentially slaves that made the wealth from Cormorant's possible. He was also much more fair in the telling of a few other stories of people of color.
2) I read this on audiobook, which was a mistake. The author would spring on the reader very graphic descriptions of violence against people and birds. These were totally unnecessary and their inclusion should have merited trigger warnings, honestly. Perhaps this author doesn't believe in those "liberal pansy ideas", but I would've appreciated it. When stuff like that comes up in a regular book, I just skim until I can tell I'm past it, but with the audiobook I just had to skip a decent amount until I figured he wasn't talking about it anymore, probably missing some good info in the process. This happened multiple times. I read this book because I care deeply about birds and the natural world. I could not stomach sudden graphic descriptions of the intentional, disgustingly cruel things people did to birds.
So I don't know what to rate this book. I can't recommend it, but I also learned a lot and will be mulling over his ideas.. while trying to forget the gross-ass violence and imperial bias I read. Do with that what you will.
