This modest, agreeable entry in the My First Look At series shows the life cycle of a mallard duck nesting in an urban park. The text is cumulative, so the line on the first page, “This is the park where Paul plays,” is echoed on the second, “These are the ducks that swim in the park where Paul plays.” In the spring the ducks arrive; they grow all summer long, and fly away in the autumn. Listeners will enjoy the spare, rhythmic telling, while the softly colored drawings of Paul, a shaggy-haired preschooler, are appealing. Additional information, obviously aimed at older readers or for adults to share with children, appears under the flap on each page. (Picture book. 4-7)
