Wolf packs often work cooperatively, as in this bison hunt at Yellowstone National Park. A pack of coyotes in Yellowstone National Park in 1999. A pack is a social group of conspecific canines. The number of members in a pack and their social behavior varies from species to species. Social structure is very important in a pack.
The wolf must give chase and gain on its fleeing prey, slow it down by biting through thick hair and hide, and then disable it enough to begin feeding. [4] After chasing and then confronting a large prey animal, the wolf makes use of its 6 cm (2 + 1 ⁄ 2 in) fangs and its powerful masseter muscles to deliver a bite force of 28 kg/cm 2 (400 lbf/in 2), which is capable of breaking open the ...
The gray wolf's expressive behavior is more complex than that of the coyote and golden jackal, as necessitated by its group living and hunting habits.

A California gray wolf, dubbed OR 85, in 2023. The wolf was fitted with a satellite collar to help the California Department of Fish and Wildlife track the state's burgeoning wolf population.

Avian social predators include the Harris's hawk, butcherbirds, three of four kookaburra species and many helmetshrikes.
