Strictly speaking, Keep On Moving: The Great Animal Migrations, Large and Small (2025) is more picture book-adjacent than a pure picture book. That is to say, it is much longer than most picture books (over 60 pages), and much wordier. In addition to the images, each page has multiple paragraphs, some with advanced or unfamiliar vocabulary. It is clearly aimed at older/more advanced readers. That being said, Sara and Olivia Forster’s book, illustrated by Terri Po, is an engaging and comprehensive introduction to the topic of migration.
One thing that makes it work is that it really does discuss migrations of many sorts and sizes, ranging from butterflies and crabs up through whales. Another thing is the global reach: the book gives examples from Europe, Asia, Africa, the Americas, and Antarctica. Details are given in each case, some in numbers (how many animals migrate, how far they go), some in descriptions, some in images. The book also addresses principles that cut across species, like the reasons that drive migration and the creatures’ relationship to their larger context.
This colorful book ends with a number of useful paired pages: two on migration of plants and seeds, two on why migration matters, two on how scientists help migration and two more on how the average person can help, closing with two pages of resources.
