Eastern wolf

The eastern wolf (Canis lycaon or Canis lupus lycaon), also known as the timber wolf, Algonquin wolf and eastern timber wolf, is a canine of debated taxonomy native to the Great Lakes region and southeastern Canada. It is considered either a unique subspecies of gray wolf, or red wolf, or a separate species from both. Many studies have found the eastern wolf to be the product of ancient and recent genetic admixture between the gray wolf and the coyote, while other studies have found some or all populations of the eastern wolf, as well as coyotes, originally separated from a common ancestor with the wolf over 1 million years ago and that these populations of the eastern wolf may be the same species as or a closely related species to the red wolf (Canis lupus rufus or Canis rufus) of the Southeastern United States. Regardless of its status, it is regarded as unique and therefore worthy of conservation with Canada citing the population in eastern Canada (also known as the "Algonquin wolf") as being the eastern wolf population subject to protection.

There are two forms, the larger being referred to as the Great Lakes-boreal wolf, which is generally found in Minnesota, Wisconsin, the Upper Peninsula of Michigan, southeastern Manitoba and northern Ontario, and the smaller being the Algonquin wolf, which inhabits eastern Canada, specifically central and eastern Ontario and southwestern Quebec, with some overlapping and mixing of the two types in the southern portions of northeastern and northwestern Ontario. The eastern wolf's morphology is midway between that of the gray wolf and the coyote. The fur is typically of a grizzled grayish-brown color mixed with cinnamon. The nape, shoulder and tail region are a mix of black and gray, with the flanks and chest being rufous or creamy. It primarily preys on white-tailed deer, but may occasionally hunt moose and beavers.

In the third edition of Mammal Species of the World published in 2005, the mammalogist W. Christopher Wozencraft listed the eastern wolf as a gray wolf subspecies, which supports its earlier classification based on morphology in three studies.
