The Windhover — Alan Brown

A kestrel chick is born and shares a nest high above a school yard with his brother and sister. They spend their days looking out over the playground, testing the wind with their downy wings, and awaiting their parents and the food they bring. But one day someone else arrives and takes one of the chicks. Torn from his family, the chick begins to die, and the kidnapper-a lonely boy-must place his trust in another child if the bird is to survive. . . .
