During the late summer and fall, coyotes really "yip it up." Despite what you can learn on Youtube, their yips and howls are family communications that have nothing to do with bloodthirsty predators circling for the kill.
The eastern coyote pack is small: an adult pair and their young. The youngsters are venturing out on their own now and adults howl to round them up. When on the prowl for food, silence is the code—which makes sense—but reuniting often inspires prolonged vocal celebrations.
In March, coyotes stalk, chase and kill winter-weakened deer in the equivalent of "Lions & Gazelles." Hungry coyotes now take prey larger than their usual fare of small rodents.
Coyotes breed in February. During March and April gestation, they select maternity dens where they'll birth pups in May. Coyotes do NOT hunt in large family packs or occupy dens in other seasons. Coyote breeding is timed to a seasonal abundance of food: deer are in weakened condition after burning winter fat reserves while traveling in snow on a meager diet of twigs, bark and buds.
