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. (Board book. 1-5)
