You would think, based on the title, cover, and back cover description, that this would be about crows.
You would be wrong.
Instead, it's a 236 page pat on her own back by the author for being oh so much more observant of nature than everyone else. She calls herself a "radical birdwatcher" and makes unsubstantiated claims about nature and then says there is no evidence for those claims, but she's making them anyway, so.
There are a few anecdotes that are vaguely about crows, but there's no particular common thread or point to any of them besides bringing it all back to the author.
