Children's book. From the book jacket: "An invitation for young naturalists to share in the experience of watching a great horned owlet become a mature bird. This day by day journal charts the young owl's development and is a chronicle of how the author and 'Bubo' come to know each other over three summers spent in the Maine woods. A story in itself, this also provides young naturalists with an example of the process of scientific observation and discovery, and shows them how to go about keeping their own field journal."
REVIEWS (3 OF 5 stars on Amazon): "Heinrich adopted a great horned owlet that he found nearly frozen to death in the Vermont woods and kept it for three years, training it to hunt for its food. This fascinating book, written in diary form, details changes in the owl's appearance as he grows, his awakening interest in the natural world around him, and his continual preoccupation with food and its capture."—School Library Journal
BERND HEINRICH WRITES ABOUT AN OWL IN THE HOUSE:
Alice Calaprice, then another editor at Princeton University Press, who had edited One Man's Owl, felt that my sketches of Bubo were appealing. She suggested using them in a children’s story of the owl. Disclaimer: the owl had really not been a house owl. It was wild in the woods but so tame as to be practically in the house—which indeed it sometimes was.
