Rebecca discovers many things about plant and animal life when she spends the day in Teatown Woods in the Hudson Highlands of New York looking for the ovenbird. But when she sets out into the forest at dawn, she never expects to find magic everywhere she looks. A squirrel flies through the air. A deer vanishes before her eyes. A wood duckling falls from the sky. And the mysterious ovenbird holds the greatest surprise of all. One in a series of chapter books for ages 7-10 that includes the prairie, desert, tropical forest and Alpine tundra.  (NYS97, $4.99)
