Migration

Get kids thinking with this primer on sky, land, and sea animal migrations.

Did you know Arctic terns migrate farther than any other animal? Gray whales can swim up to 12,000 miles during their migration journeys and Emperor penguins walk about 125 miles over ice to reach their nesting grounds.

Gail Gibbons explores the many reasons why animals migrate, using direct sentences, maps, infographics, and illustrations. Featuring over 30 different species of mammals, birds, reptiles, insects, and fishes, this nonfiction picture book is perfect for aspiring zookeepers and animal-lovers. Fully vetted for accuracy by James Doherty, Curator Emeritus, The New York Zoological Society.

This title is part of the Explore the World . . . with Gail Gibbons series, which promotes active learning, good citizenship, and student leadership.

In contrast, Direct Market (DM) and variant covers are primarily sold in comic shops. DM editions tend to have more limited availability and may be more valuable to collectors.
