It's spring and everywhere birds are calling out to each other. But one bird has forgotten which sound to make. He tries "Woof," and meets a dog, who encourages him to try "Oink," with the expected result. Moo, Hee-Haw, Baa, Meow--each successive call adds another animal friend to the page. Will the young bird find another bird friend? As young readers are introduced to each type of animal and their sounds, Hendrik Jonas's clever illustrations grow increasingly crowded. The result is a beautiful celebration of friendship that will delight young children everywhere.
