[>] "less vocal than coyotes": Joel Berger, a senior scientist at the Wildlife Conservation Society who has studied large mammals in both North America and Africa, suggests that the question of whether coyotes bark more than jackals can be addressed by inference. "Coyotes," he says, "live in an environment where only two predators habitually prey upon them—wolves and mountain lions. The cost of a coyote announcing itself to another coyote by barking is thus rather low. Jackals, on the other hand, live among lions, hyenas, leopards, cheetahs, and wild dogs, all of whom would be more than happy to make a meal out of a jackal. Therefore, the cost to a jackal, for revealing its position by barking, can be quite high." (Joel Berger, telephone conversation with author, 22 July 2005.)
