Harpy eagles are really cool. I didn't really learn anything new in this book, but I enjoyed revisiting these cool creatures. This rain forest eagle is one of the largest birds of prey, nesting in tall rainforest trees and preying on monkeys, sloths, coatis, and other medium-sized creatures.
My favorite part of the harpy eagle is the way they can pop up a circle of feathers around their face. This has a practical use - directing sound to their small ears - but it also looks simply adorable. It's this big fluffy circle (with, you know, a razor-sharp beak in the center).
In addition to the facts about the harpy eagle, its habitat, prey, and life cycle, there are also inset facts about the eagle and the rainforest, questions to get readers thinking about the text, a science experiment, glossary, and index.
Verdict: If you're looking to diversify and add to your animal books, this series is a good choice to fill out some more unusual predators.
