This is a great book, perfect for primary science units.  It’s a photo journal chronicling every step along the way as a couple of blue jays find a spot to build a nest (right outside the author’s window), find things to build it with, lay their eggs, and feed the hungry newborns, right through to the first explorations beyond the nest, and setting out to see the world.  The text is very clear and kid-friendly, and full of the author’s own excitement and wonder as he watched the story unfold before him.  A few of the photos are less than clearly focused, but that just speaks to the serendipitous nature of how the book came about.  The reader feels lucky to have gotten to share in this experience of urban wildlife, of which few of us would get to see such a close-up view on our own.
