Abstract

Lay Summary Not all predators are created equal. Here we show that Steller’s jays assess the level of risk a predator poses by the interaction between 4 different predator species and whether they heard or saw the predators. Sharp-shinned hawks are threatening regardless of being seen or heard where northern goshawks are more threatening if seen than heard. Furthermore, Steller’s jays alter their alarm calls in subtle ways in response to these differences.
