This charmingly illustrated board book in the Animal Clues series may prove confusing to the conventional board-book audience. Twinem invites onlookers to guess which creature is described in brief word clues, beginning with a close-up of an oval black eye: ""My eyes are small and dark."" The next frame shows a feathered throat, and later references are made to a long bill, sipping nectar, and hovering in the air. ""I am a hummingbird!"" Sweet, but of limited usefulness.
