What is the summary of Chapter 18?

The Earth Calls Frightful – At last, Frightful heads south. Sam and Alice call their goodbyes. Sam tells Frightful he’ll be waiting to see her in the spring. Frightful meets up with Drum and other birds of prey and continues south with them. She and Drum hunker down as a hurricane passes through, and then continue on. They fly over Florida and through Cuba, on toward Belize. Frightful and Drum part ways, and Frightful comes to rest on Espanola Island. She eats and then heads to Gardner’s Island, where she seeks out more food, and flies back to Espanola Island. In the tropics, falcons fly for pleasure, and Frightful enjoys this for two months. She also notes how tourists can walk right up to animals to take pictures, since all the wildlife is unused to humans, and don’t know they are predators. Frightful feels the call to head back north on December 21, and narrowly avoids being attacked by Galapagos hawks. She travels for days and comes to rest on Cocos Island. Near Cuba, she meets up with Drum, and heads to Florida. Soon after, Frightful returns to her mountain.
