Translated to Latin, "barking dog" is Canis latrans... we call the mammal represented by this name a Coyote.
At the time of European settlement in North America, Coyotes were restricted to the prairie region of the continent west of the Mississippi River. As a result of clearing forests for agriculture and corridors for roads, as well as the removal of the dominant predators Gray Wolf (Canis lupus) and Red Wolf (Canis rufus), the range of the Coyote began to expand. By the early 1900s, Coyotes were found throughout much of the western two-thirds of North America. By 1990, Coyotes had expanded their range from coast to coast.
The photo above was taken last weekend from our car at the intersection near Gary Avenue, Cline Avenue, and I-90 in Gary, Indiana. As stated above, Coyotes are benefitting from the geographical expansion of the human population, and are now showing up in the strangest of places (such as this one that was found in a Chicago sub shop). However, researchers have shown that Coyotes are becoming more nocturnal as a result of pressure from humans.
