No iguana wants to be cooked alive on a hot rock and then served up as dinner for a Galapagos hawk. But it turns out the marine iguanas (Amblyrhynchus cristatus) have a strategy that warns them of the presence of hawks they can’t see. They learned to tune in to a kind of police scanner…the alarm calls of mockingbirds.
