Grizzly bears, black bears, wolves, coyotes, cougars/ mountain lions,bobcats, wolverines, lynx, foxes, fishers and martens are the suite of carnivores that originally inhabited North America after the Pleistocene extinctions. This site invites research, commentary, point/counterpoint on that suite of native animals (predator and prey) that inhabited The Americas circa 1500-at the initial point of European exploration and subsequent colonization. Landscape ecology, journal accounts of explorers and frontiersmen, genetic evaluations of museum animals, peer reviewed 20th and 21st century research on various aspects of our "Wild America" as well as subjective commentary from expert and layman alike. All of the above being revealed and discussed with the underlying goal of one day seeing our Continent rewilded.....Where big enough swaths of open space exist with connective corridors to other large forest, meadow, mountain, valley, prairie, desert and chaparral wildlands.....Thereby enabling all of our historic fauna, including man, to live in a sustainable and healthy environment. - Blogger Rick

In addition to hoofed browsers like Deer, Moose, Elk, Bison and Caribou, Wolves will hunt Beavers...........Where both animals roam the landscape, Beaver can account for as much as 60% of Wolves Summer diets............And unlike in most cases with the hoofed browsers, it is possible for a single Wolf to subdue and kill Beavers---but know that a full out caloric output is needed for the Wolf to dine successfully........Caught on video is the millenia-old drama of Wolf versus Beaver

wolf vs beaver !


Wolves predominately prey on hoofed animals
 including Deer,
 moose, Bison, Elk, and caribou. Because
 wolves usually hunt
 for large animals, (although wolves are 
opportunistic and will 
eat smaller prey) they work together to
 catch their prey. Wolves 
will eat a healthy, strong animal if they
 can catch it. (Wolves
 need an average of three to ten pounds
 of meat each day).
 will also
 eat grass
 purge their
 when they have eaten
 something that does not
 agree with them. Food sources may
 differ and change
 depending on the season and
geographical area, when
 large prey animals are scarce wolves
 will prey on mice,
 Rabbits and squirrels, these smaller
 prey do not provide
 a substantial part of the wolf's diet
 but supplement it
 when larger prey are scarce.
Beavers play an important roll 
as an alternative food
 source in the summer months,
 in some areas 60%
 of the wolf's diet is beaver.
One of the most odd part of the diet of
wolves is fish! Biologist Bod Bromley
 once observed a wolf in Canada's
Northwest Territories catch five fish
 in fifteen minutes in the Talston River.
Wolves will also scavenge, In one
study of moose carcasses in
Algonquin Park, of 30 moose only 4
were killed
 by wolves,
 the rest died of natural causes.
Wolves will also eat wild berries and
other fruit as a minor part of their diet.

Where and How

 Wolves (Canis lupus

Kill Beavers (Castor canadensis)


Beavers (Castor canadensis) can be a significant
 prey item for wolves (Canis lupus) in boreal
ecosystems due to their abundance and
vulnerability on land. How wolves hunt beavers in
 these systems is largely unknown, however,
because observing predation is challenging.
We inferred how wolves hunt beavers by
identifying kill sites using clusters of locations
from GPS-collared wolves in Voyageurs National
 Park, Minnesota. We identified 22 sites where
wolves from 4 different packs killed beavers.
We classified these kill sites into 8 categories
 based on the beaver-habitat type near which
each kill occurred. 
Seasonal variation existed in types of kill sites
 as 7 of 12 (58%) kills in the spring occurred at
 sites below dams and on shorelines, and 8 of
10 (80%) kills in the fall occurred near feeding
 trails and canals. From these kill sites we
deduced that the typical hunting strategy has
3 components: 1) waiting near areas of high
beaver use (e.g., feeding trails) until a beaver
comes near shore or ashore, 2) using vegetation,
 the dam, or other habitat features for concealment,
 and 3) immediately attacking the beaver, or
ambushing the beaver by cutting off access to water.
By identifying kill sites and inferring hunting behavior
 we have provided the most complete description
 available of how and where wolves hunt and kill
Examples of evidence found at beaver kill sites (A,B,C), and 
of wolf behavior when in active beaver habitats (D) in Voyageurs
 National Park 2015. A) Matted vegetation at kill sites provided 
important information about how wolves killed beavers. B) Co-author
