The great rivers of North America are teeming with life and on the pages of Over in a River - from blue herons in the Hudson to salmon in the Columbia, and from dragonflies in the Rio Grande to mallards in the St. Lawrence. Children will "slither" like water snakes and "slide" like otters while singing to the tune of "Over in a Meadow." And they'll count baby animals in watersheds all over North America What a delightful way to learn about riparian habitats and geography at the same time
