But the coyote sure is having fun.

...The canid has been referred to in scientific publications as Canis latrans, Canis latrans var., and Canis latrans × Canis lycaon, and has been commonly referred to as the eastern coyote, northeastern coyote, and coywolf. It is also called the southern tweed wolf.
Coyotes and wolves first hybridized in the Great Lakes region, followed by a hybrid coyote expansion that created the largest mammalian hybrid zone known. In 2014, a DNA study of northeastern coyotes showed them on average to be a hybrid of western coyote (62%), western wolf (14%), eastern wolf (13%), and domestic dog (11%) in their nuclear genome. The hybrid swarm extended into the midwestern United States, with Ohio coyotes shown on average to be a hybrid of western coyote (66%), western wolf (11%), eastern wolf (12%), and domestic dog (10%) in their nuclear genome.
For northeastern coyotes, hybridization with the dog was estimated to have occurred between 11 and 24 generations ago, and there is no evidence of recent dog-coyote crossing. There was some evidence of first and second generation wolf-coyote hybrids back-crossing with coyotes. For Ohio coyotes, the wolf DNA was present in the nuclear genome but not the mitochondrial genome, indicating hybridization between male wolves and female coyotes. For northeastern coyotes, the dog DNA was present in the nuclear genome but not the mitochondrial genome, indicating hybridization between male dogs and female coyotes. Although hundreds of northeastern coyotes showed maternal wolf DNA, nearly all were the same haplotype that indicated a past single hybridization between a female wolf and a male coyote. These findings support the hypothesis of sexual interaction based on body size, with the larger species male almost always crossing with the smaller species female.
Northeast coyotes benefit from a more diverse genome that includes genes from both wolves and dogs, which has likely allowed their adaption to both forested and human-dominated habitats. Coyotes moved into the northeast after they began to hybridize with wolves between 154 and 190 years ago. Coyotes are more genetically wolf-like in areas where a high deer density exists, supporting the theory that introgression from wolves allowed genetic adaption to this food source. There are an estimated 16–20 million white-tailed deer in the United States, and their overpopulation is estimated to cause $2 billion in damage each year, with $1 billion in automobile damage alone. Management practices should consider the ecological value of large predators in maintaining their balance.
