When Wren was born, Grandpa put a wren box just outside the window of her tiny room.   When she was a baby, the wrens sang her to sleep. Each spring, Wren and Grandpa watched the birds bringing sticks and grasses to the box and listened when the babies squealed for their dinner. When Wren's family moves to the city, she misses birdwatching in the meadow. Their new home has an extra bedroom, but the only birds she can see are pigeons. Lots of pigeons. But when Wren and her grandpa discover a phoebe nest in the rafters above their porch, they get a front-row seat to the miracle of new life—both in nature and in their own home. With ecological backmatter about what to do if you find a bird's nest and other birdwatching resources, this gorgeously illustrated picture book explores the sweet relationship between grandfather and granddaughter, as well as the anticipation of a new arrival.
