There's a good reason why the howler monkey got its name its howls aren't just loud, they are louder than any other monkey in the forest. In fact, this little noisemaker is one of the loudest animals in the world! Its booming sounds can be heard for at least a mile (1.6 km). These are just some of the surprising facts kids will discover as they learn about the howls, growls, and roars that these noisy creatures make. Eye-popping photos and clear, easy-to-read text will engage emergent readers as they come face-to-face with these animal loudmouths. In addition, children discover where the animals live, how they stay safe, and the different ways their sounds help them communicate with each other and tell other howler monkeys to stay away! A "Sound Check" chart at the end of the book compares the decibel level of the howler monkey to everyday objects, including an airplane, a lawnmower, and a train engine.
