White-throated magpie-jays protect themselves against predators through their social behavior, including mobbing behavior and alarm calls. Raptor alarm calls are harsh and may vary in intensity given the threat at hand. Raptor alarm calls cause any white-throated magpie-jay nearby to dive for cover. More moderate alarms are called when a bird approaches or when other predators are observed. These birds may even give alarm calls at the site of a car. They also give a loud alarm when a nest is approached by both humans and natural predators, which doubles as a mobbing call.
