“‘What do birds do all day long?’ Ecology professor Hauber answers this question by taking an hour-by-hour, worldwide tour of two dozen bird species. . . . Short vignettes about each bird are beautifully illustrated with Tony Angell's lively drawings, bringing the wonders of bird behavior to life.”

Booklist

"A delightful book by research ornithologist Mark Hauber and illustrator Ton Angell. From owls hunting at night to the common pochard resting with an eye open to spot predators in the daytime, this is a global, hour-by-hour account of individual bird lives."

New Scientist

"Fine drawings by Tony Angell, with a grey background, have a quality recalling old woodcuts."

Birdwatching Magazine

"[A] delightful, rather quirky window into the world of birds. . . . Hauber’s enthusiasm comes across on every page and Angell’s drawings are superb, capturing the essence of each species to complement the text and illustrating the dark and light hours. This is a book to read in an hour but then to leave around to pick up and savour each entry and its corresponding drawing."

“Bird Day is a brisk, high concept read. It lends the reader a pair of giant wings to soar across the globe, peeking in each hour on the lives of the world’s most fascinating birds. Author Mark Hauber is a research ornithologist, and the text often draws upon his studies. We meet cooperatively breeding superb starlings; a secretary bird that stomps venomous snakes into submission; a duck, keeping one eye open while sound asleep; a bat hawk that swallows its nocturnal prey whole. Lushly patterned chiaroscuro drawings by Tony Angell heighten the mystery and delight of these tall-but-true bird tales.”

Julie Zickefoose, author and illustrator of “Letters from Eden,” “The Bluebird Effect,” “Baby Birds,” and “Saving Jemima”

“A wonderful book that simultaneously made me nostalgic about a cave full of oilbirds in Trinidad and a kiwi running between my legs in a New Zealand sleet storm—and further informed me about the lives of birds. A brilliant collaboration between a first-rate behaviorist and my favorite bird artist.”

Paul R. Ehrlich, author of "Life: A Journey through Science and Politics" and "The Birder's Handbook"

“As much a meditation as a book, Hauber and Angell’s Bird Day gives us a bird to think about at each hour of the day and night. They take us around the world, visiting birds including the brown-headed cowbird (5 a.m.), Hauber’s own research subject, the ocellated antbird (noon), Cook’s petrel in New Zealand (10 p.m.), and twenty-one others. The narrative brilliantly captures the moment; the art makes the moment come alive. Bird Day is an excellent pairing of text and art, one I will return to again and again as the hours go by.”

Joan E. Strassmann, author of "Slow Birding: The Art and Science of Enjoying the Birds in Your Own Backyard"

“One could not ask for two better field companions than Mark Hauber and Tony Angell as they observe some of the world’s most interesting birds. Their book gives us all new ways of seeing, hearing, and thinking about them—hour by hour—without ever leaving home.”

Robert McCracken Peck, author of "A Celebration of Birds" and "The Natural History of Edward Lear"

“Stunning. . . . Sometimes we are oblivious to miraculous objects in our daily lives.”

“Angell writes (and draws) with the absolute authority of one who has studied, rehabilitated, lived with, and loved the animals his whole life.”
