All the Lortons’ farm animals – the cows and the goats, the ducks and the chickens, got along well with Roger—a llama(美洲驼). But since llamas are used to thinking of animals like coyotes(土狼) and dogs as threats, it took Roger a few weeks to accept the family dog.
Roger protects the sheep and lambs in two ways. First, he keeps the sheep together. A hungry coyote will try to scatter(分散) the flock and then pick off a weak or small animal that has become separated from the rest. But when a coyote threatens the Lorton’s sheep, they all run to Roger, depending on him to defend them.
And he does, with his second defense: confronting(对抗) the coyote. Llamas are very curious and will run at top speed to investigate anything that looks interesting. When a coyote sees a three-hundred-pound llama rushing toward it, the coyote will not usually wait around to see what the llama wants.
And once a llama realizes that a coyote is threatening the flock, the llama will stand between the coyote and the sheep to defend them. Often, the llama will charge toward the coyote with its head down. As it runs, it will sometimes call out an alarm to the flock in a high-pitched voice. Since Roger’s arrival, coyotes haven’t gotten any sheep from the Lortons.
