Great Migrations Butterflies (National Geographic Kids Readers, Level 3)

Seemingly delicate monarch butterflies undertake one of nature's toughest migration journeys each year, flying thousands of miles in search of warmer temperatures. Learn about their awe-inspiring travels in this photo-filled Level 3 Reader from National Geographic Kids.

Making the yearly trip from the Northern United States and Canada to the Oyamel forest of Mexico is no easy task, and it takes five generations of butterflies in order to do so. Learn about how these beautiful insects battle cold temperatures and the threat of starvation to complete an almost 3,000 mile journey over the course of two months, only to have to turn and around and head back home.

Featuring expert-vetted text, brilliant images, and a fun approach to reading, National Geographic Kids Readers are proven to be winners with kids, parents, and educators.

NGK Level 3 Readers are ideal for children who are reading fluently on their own, with layered information and varied sentence structures.
