Young Spanish readers will be implementing inferential skills, predictions, and drawing conclusions to determine what animal is hiding in the page-by-page text and photographs. This nocturnal animal that can live in old barns, that has keen hearing and strong wings, is revealed at the concluding page to be the owl. This book is part of the "Guess Who" series and is from the three leveled reading "Bookworms" program. Each level of the program helps readers reinforce reading skills. The other levels are emergent and fluent. Included at the end of the book are the close-up photographs from the text asking "Who am I?" plus one challenging word from the text and an index. The photographs of the owl in its natural habitat authenticate the facts and information presented through the simple sentence structure. The maximum number of sentences per page is three in this twenty-six page book.
