Only about 5 percent of mammal species are truly monogamous. Among members of the canine family, most— including foxes, wolves, and jackals— form strong pair bonds, but are often observed “cheating” on the side. Not so with the coyote. It is one of the only mammal species known to form truly faithful, monogamous pair bonds that last a lifetime.
Coyotes normally find a mate in late adolescence, when youngsters first set out on their own away from their parents. Once mated, the pair will work side by side to raise their young each year, and may raise as many as ten litters in their lifetime together.
Just like humans, coyotes grieve for their lost mates and may never recover from the loss. A widowed coyote with pups is very unlikely to be able to raise the pups alone. Without a partner to help defend the home, the widowed coyote may lose its den, kills, and hunting grounds to rivals. They are condemned to live a life alone, as an adult coyote will rarely be able to find a new mate.
Please be kind to your wild neighbors. They have loved ones who need them!
