If you’re a black-tailed deer on the Olympic Peninsula in the U.S. state of Washington, you’re always surrounded by friends and family. You are free-range, with abundant food to forage in familiar woods and meadows. But you’re also vigilant because you’re a prey species and your ideal habitat is also home to your top predators: Cascade mountain wolves (Canis lupus fuscus), cougars (Puma concolor) and black bears (Ursus americanus). Avoiding the animals that will hunt you and your fawns is an integral part of how you move across the landscape.
