This is a well-researched non-fiction picture book about a species of seabird called the marbled murrelet.  This little seabird migrates deep into the forest canopy of North America to nest,  lay its eggs and raise its chick.  The author’s sources as well as relevant web sites are listed at the back of the book.  The end pages provide facts about the marbled murrelet’s habitat using a watercolor illustration of old growth trees.  The rich illustrations are large, realistic and detailed.  The text is interesting and engaging.  I wanted to read to the end to learn more about this interesting seabird.  I highly recommend this book for an elementary school library.
