Coyotes are known to be one of the most vocal wild canids and are capable of producing a wide range of vocalizations, including barks, yips, howls, growls, and whines. However, when it comes to the sounds they make when killing, there is limited information available. In this response, we will discuss the vocalizations coyotes make during hunting and killing, based on the available research and observations.

Coyotes are opportunistic predators that hunt a variety of prey, including small mammals, birds, reptiles, and even deer. They are also known to scavenge on carrion and eat plant-based foods. When hunting, coyotes often work in packs, coordinating their efforts to chase down and capture their prey.
One of the most commonly observed vocalizations during a coyote hunt is the yip. Yips are high-pitched, short barks that coyotes use to communicate with each other. Yips can be used to coordinate the hunt, signal the presence of prey, and communicate other information such as the location of the pack. Yips are also commonly heard during social interactions between coyotes, such as play behavior and courtship.
Growls are another vocalization that coyotes may use during hunting and killing. Growls are low-pitched, guttural sounds that are typically associated with aggression and dominance. When hunting in packs, coyotes may use growls to intimidate their prey, or to signal to each other during the chase.
Coyotes may also produce whines and screams during a hunt. Whines are typically high-pitched and may be used to express submission or anxiety. Screams, on the other hand, are loud, high-pitched vocalizations that can be heard over long distances. Coyote screams are often associated with intense emotional states, such as excitement, fear, or distress. It is unclear if coyotes make these sounds specifically during the killing of prey, but they may be heard during the chase or immediately after the capture.
Despite their reputation as fierce predators, coyotes are not always successful in their hunts. When they fail to catch their prey, they may produce a series of howls, often referred to as a “group yodel.” Group yodels are high-pitched, wailing vocalizations that are believed to be a form of communication between members of the pack. The purpose of group yodels is not entirely understood, but they may serve to re-establish contact between pack members, coordinate their efforts, or signal their presence to other coyotes in the area.
In conclusion, while there is limited information available on the specific vocalizations coyotes make when killing, we know that coyotes use a variety of vocalizations during hunting and capturing prey. Yips, growls, whines, and screams are all vocalizations that may be heard during a coyote hunt. However, it is important to note that vocalizations are just one aspect of coyote behavior during a hunt, and there may be many other behaviors and cues that are important for understanding the dynamics of their hunting strategies.
