I am in approximately 30th grade at this point, but I still get the back-to-school itch. I like pens and backpacks and the autumnal feeling that this year I鈥檒l be smarter than the last. Luckily, a crop of new books this fall scratch that itch. Forthwith, deep dives into penguins鈥 sexual deviance, philosophical rambles across landscapes, obscure forensic-ecology facts, and more.
鈥A Polar Affair,鈥櫬燽y Lloyd Spencer Davis

Thirty years into what he thought was pioneering work on the complicated sex lives of Ad茅lie penguins, polar researcher Lloyd Spencer Davis, who calls himself Professor Penguin, found a surprise. He uncovered papers showing that early-20th-century explorer Gregory Murray Levick had already made the same observation about penguin homosexuality and polygamy. But Levick obscured his research, because he apparently thought it was too disturbing and raunchy. The hidden story uprooted Davis鈥檚 ideas of science and censorship, and in , he digs into the details of what Levick found聽and tries to figure out why it was hidden. Come for the penguin promiscuity, stay for the stories of historic polar explorers and a thoughtful analysis of why science isn鈥檛 always exactly what it seems.
鈥The Nature of Life and Death,鈥櫬燽y Patricia Wiltshire

What is the nexus of true crime fans and plant nerds? Possibly this website聽but also , forensic ecologist Patricia Wiltshire鈥檚 book about her career using the natural world to solve crime. If you鈥檝e ever wondered what it might take to get pollen spores out of a dead guy鈥檚 nose鈥攁nd then whether聽those spores might provide clues to the scene of a聽crime鈥攖his is your book. Wiltshire writes like the scientist she is, so her prose can be dry at times, but the subject matter is fascinating, and Wiltshire makes a good case for curiosity as she steps through the process of tracking details and solving mysteries.聽
鈥Surfacing,鈥櫬燽y Kathleen Jamie

is a great companion for autumn鈥檚 natural melancholy and meditative feel. Scottish poet Kathleen Jamie weaves together lucid essays about aging, archaeology, travel, and the erosion of natural resources and sacred wild places. She captures that end-of-summer sadness, when you鈥檙e taking stock of your year and slowing down as the days get shorter. The book is about changing landscapes and human impact, but it鈥檚 also about memory and paying attention, as she visits Ice Age caves and rides on high-speed trains. It鈥檚 a series of tight visual scenes, beautifully told, and it鈥檚 worth blocking out an afternoon to spend time with.
鈥Virga and Bone,鈥櫬燽y Craig Childs

While Jamie is tight and restrained, American essayist and adventurer Craig Childs is full of rawness and spark, just like the dry southwestern deserts he loves and has been eulogizing for more than two decades. is a collection of eight essays about those places聽and the people who need them, abuse them, love them, and take them for granted. Childs says that he only writes about聽humans, to show the scale of the natural world, but those descriptions form the most powerful parts of the book. 鈥淒eserts are mummifiers, bone-makers,鈥 he writes. 鈥淪ome years the rains won鈥檛 come, clouds promising and promising, but did you say the right prayers? Did you pray to the right god?鈥
鈥A Short Philosophy of Birds,鈥櫬燽y Philippe J. Dubois and Elise Rousseau

If you鈥檙e mourning the loss of or scanning the sky for migrating geese, you might find some levity in . It鈥檚 a series of short essays about avian behavior聽and what humans might stand to learn from birds鈥櫬爈ives: stories of resurrection and forgiveness are told though molting ducks and gender equity among sandpipers. The result is a mix of natural history and behavioral science with a side of life skills. Sometimes the anthropomorphizing can feel slightly heavy-handed, but overall the book is both joyful and interesting, and if nothing else, it might motivate you to keep your eyes on the sky.
