Coyotes have many ways of communicating with each other and with other animals. The most familiar form of communication is vocalization, or making different sounds. Many other animals communicate through vocalization: dogs bark when they feel threatened; cats purr when they are content; birds chirp and sing to attract other birds. Coyotes use four different types of sounds to communicate: howling, barking, yelping, and huffing.
Howling is the coyote sound that is most commonly heard. Coyotes howl to "talk" to other coyotes in the area. The howl lets other coyotes know where they are. It also helps to reunite separated members of the pack. The howl is a high-pitched, eerie noise. It is usually heard at night. Sometimes, other coyotes will join in the howling.
Coyotes bark when they are trying to protect themselves or their families. The bark is warning noise. It tells enemies to stay away. It sounds similar to a dog's bark.
The final type of vocalization that coyotes use is called huffing. This is a low-pitched, quiet noise. Female coyotes use it to call their pups.
In addition to vocalization, coyotes communicate with each other and with other animals by "marking their territory." They do this by making a border with urine or "scat" (droppings). By marking an area with urine or scat a pack of coyotes can claim an area as its own. Neighboring packs are hesitant to cross into "marked" territory.
