Line up for this fascinating exploration of animal behavior from an award-winning author-illustrator! Much like humans, many animals line up for a variety of reasons. Rather than forming lines for the school bus or recess, the animals featured in Susan Stockdale's book form lines for * safety: baby Mallard ducklings follow their mother to the water for their first swim * care: spotted white-spotted puffer fish form a line so that each fish can be cleaned by striped cleaners * navigation: artic wolves follow the prints in the snow left by the pack leader * travel: pink flamingos form a line to reduce wind resistance and fly more efficiently * rest: turtles form a stack to keep warm while they sleep Featuring a variety of birds, crustaceans, fish, insects, mammals, and reptiles from around the world, Line Up is a cozy and comforting book that reminds us of our similarities while illuminating some specific, distinctive behaviors.
