I'm reading "Birdology" by Sy Montgomery, all about how birds are descended from dinosaurs and smart and resilient and long-lived for their size and totally foreign to the way mammals view the world. Their eyes have three types of rods and cones and two focal points instead of one and they can sense the earth's magnetic fields.
Sy's writing reminds me quite a bit of Mary Roach, whose books Stiff, Gulp, Bonk, Packing for Mars, etc are similarly popular science for lay readers.
