“Duck? / Yup, you’re a duck! / I’m a duck. Yup, / by some magnificent / stroke of good luck, / I’m a duck!” An exuberant duckling is amazed at all the wonderful aspects of duck-ness. He can quack. He has webbed feet that leave little tracks. He has wings that can flap. He can fly! Then he meets another duck, and she’s a girl. More good luck: They have ten eggs. And from those ten eggs come ten more ducks! Imagine the luck. The only thing he likes more than being a duck is being a dad. Sloat has created an energetic celebration of self that just happens to be peopled by ducks. The rhyming text flows alongside the glowing pastel illustrations. The expressive duck family is portrayed with an excellent mix of naturalism and anthropomorphism. Who knew a duck’s bill could smile so? Storytimers will wish they too were ducks. (Picture book. 2-6)
