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.
