Book excerpt: This fascinating picture book biography from beloved author of the Lemonade War series Jacqueline Davies and Caldecott honor–winning illustrator Melissa Sweet chronicles the life of scientist John James Audubon, who pioneered a technique essential to our understanding of birds thanks to his lifelong love for the species. If there was one thing James loved to do more than anything else, it was to be in the great outdoors watching his beloved feathered friends. In the fall of 1804, he was determined to find out if the birds nesting near his Pennsylvania home would really return the following spring. Through careful observation, James laid the foundation for all that we know about migration patterns today. Capturing the early passion of this bird-obsessed young man as well as the meticulous study and scientific methods behind his research, this lively, gorgeously illustrated biography will leave young readers listening intently for the call of birds large and small near their own home.
