Spring has arrived, and along with it comes a flock of books about our feathered friends. Here are three new titles that bird watchers will find especially intriguing.

Jennifer Ackerman, longtime nature writer and contributor to Scientific American, thinks it's time to ditch the term "bird brain." In The Genius of Birds, she offers compelling evidence that birds are far smarter than we previously thought. In fact, she writes, new research has found "bird species capable of mental feats comparable to those [of] primates." Birds can recognize human faces, use geometry to navigate, learn new skills from one another (like how to open milk bottles) and even work puzzles. The author travels from the South Pacific—home of the world's smartest bird, the New -Caledonian crow—to rural China as she explores the surprising cognitive abilities of birds. Ackerman is a pro at parsing scientific concepts in an accessible style, and her lyrical writing underscores her appreciation for the beauty and adaptability of birds.

NATURE'S CREATION
While bird brains are the focus of many new studies, there's nothing more beautiful or delicate than a brightly colored bird's egg. In The Most Perfect Thing: Inside (and Outside) a Bird's Egg, ornithologist Tim Birkhead deconstructs every part of the egg to reveal how these small survival pods are "perfect in so many different ways." From the shell (composed of upright crystals "packed against each other like a stack of fence posts") to the albumen (the "absolutely remarkable, mysterious stuff" that most of us call the white part), the elements are described here in exquisite detail. Like a bird watcher who spots a rare specimen, the author shows palpable (and charming) excitement for his subject throughout, never losing his sense of wonder and admiration for nature's "ingenious construction" of the egg.

IN THE NEST
A contributing editor of Bird Watcher's Digest, Julie Zickefoose has a particular fascination with baby birds and enjoys painting these scrawny, screeching creatures from the moment they hatch to the day they leave the nest as fledglings. Baby Birds: An Artist Looks into the Nest offers a rare and meticulously chronicled portrait of baby birds' day-to-day development, with the author's lovely watercolor paintings adding a vivid visual dimension. In her introduction, Zickefoose describes Baby Birds as "an odd sort of book, like a Victorian-era curiosity." Fans of the rediscovered 1970s bestseller The Country Diary of an Edwardian Lady will happily agree.

Ackerman (Ah-Choo! The Uncommon Life of Your Common Cold; Sex Sleep Eat Drink Dream: A Day in the Life of Your Body) documents the amazing and almost unbelievable abilities of birds to migrate great distances, remember where thousands of food items are stored, and adapt to nonnative areas. Also described are the virtuoso skills of birdsong (some creatures are capable of hundreds of vocalizations) and the artistry of nest builders, such as bowerbirds, which favor artificial blue objects. More than 50 pages of notes support the eminently readable text. Other engaging chapters detail birds' use of tools, problem-solving skills, and intelligence and language-acquiring talents, especially those of some parrots. The author's extensive review of world biological literature, contacts with experts, and global travel enhance this fascinating title. Ackerman demonstrates that in many cases the most successful birds have, perhaps not surprisingly, the largest brains in proportion to body size. VERDICT Highly recommended for all interested in natural history, behavior, and ecotravel.—Henry T. Armistead, formerly with Free Lib. of Philadelphia

Popular science writer Ackerman (Ah-Choo!: The Uncommon Life of Your Common Cold) puts paid to the notion of being birdbrained with this survey of the observational and experimental evidence for impressive bird cognition. She explores birds' capacities for tool use, socialization, navigation, mimicry, discrimination, and possibly even theory of mind. Ackerman interviews specialists without overindulging in research travelogue, keeping centered on her feathered subjects rather than on the human interactions, and urges against anthropomorphizing bird behavior, correlating specific behaviors to generalized intelligence, or benchmarking the value of avian mental skills to that of humans. But her most interesting bits of trivia play to that urge: undergraduates who fail at mental simulations at which some birds succeed, bowerbirds trained to distinguish good human art from bad, Thomas Jefferson's mockingbird singing "popular songs of the day," and pigeons learning to open automatic cafeteria doors. Though Ackerman's focus is mainly ethological, she also speculates on the possible relationships between complex task completion and evolutionary fitness. This light popular science read doesn't present much new framing or insight; Ackerman seeks out current research to discover a few surprises, such as a possible role for olfactory cues in navigation, but doesn't point to or create any big conceptual shifts.
