These clever creators’ final collaboration arrives 40 years after their first, Brown Bear, Brown Bear, What Do You See?, joining two previous bear sequels. Much in the same vein as its predecessors, this appealingly cadenced story introduces a sequence of animals, dramatically yet simply depicted in textured collage art against white backdrops. Readers first spot Baby Bear climbing a tree, responding to the question posed in the title: “I see a red fox slipping by me.” Red Fox in turn spies a flying squirrel gliding by, who sees a mountain goat climbing nearby, who sees a blue heron flying by and so on until a screech owl—gazing wide-eyed at the reader—sees “a mama bear looking at me.” A large-scale image of Mama Bear is followed by a spread revealing what she sees: each of the previously featured animals and (most satisfyingly) “my baby bear looking at me—that’s what I see!” Creative action words and renderings of the various creatures in motion give the book a pleasing energy, while Mama Bear’s obvious delight at finding her cub provides an endearing poignancy. The elegant balance of art, text, emotion and exposition is a Martin and Carle hallmark; they have crafted a lovely finale to an enduring series. Ages 2-8. (Aug.)
