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

So you think your house cat is smart?????? Our Wildcats, the Einsteins of the Feline world

our wild cats learn(yes learn) to mimic the sounds of their prey and utilize this ability in their hunting strategy..........Margays and perhaps cougars and Jaguars appear to have this ability!
 
Clever cats use mimicry when hunting
by Kate Melville

In a fascinating example of vocal mimicry, researchers have documented for the first time a margay wild cat (Leopardus wiedii) imitating the call of its intended victim: a small, squirrel-sized monkey known as a pied tamarin (Saguinus bicolor).

The extraordinary behavior was recorded by researchers from the Wildlife Conservation Society (WCS) and Federal University of Amazonas (UFAM) in the Amazonian forests of Brazil. The observations confirmed what until now had been only anecdotal reports from Amazonian inhabitants of wild cat species - including jaguars and pumas - mimicking primates and other species in order to draw them within striking range.

"Cats are known for their physical agility, but this vocal manipulation of prey species indicates a psychological cunning which merits further study," reported WCS researcher Fabio Rohe in the current issue of Neotropical Primates.

Researchers observed the trickery when a group of eight pied tamarins were feeding in a ficus tree. They then observed a margay emitting calls similar to those made by tamarin babies. This attracted the attention of a tamarin "sentinel," which climbed down from the tree to investigate the sounds coming from a tangle of vines called lianas.

While the sentinel monkey started vocalizing to warn the rest of the group of the strange calls, the monkeys were clearly confounded by these familiar vocalizations, choosing to investigate rather than flee. Four other tamarins climbed down to assess the nature of the calls. At that moment, the margay emerged from the foliage and moved towards the monkeys. Realizing the ruse, the sentinel screamed an alarm and sent the other tamarins fleeing.

While this specific instance of mimicry was unsuccessful, researchers were amazed at the ingenuity of the hunting strategy. "This observation further proves the reliability of information obtained from Amazonian inhabitants," said Dr. Avecita Chicchón, director of the WCS's Latin America Program. "This means that accounts of jaguars and pumas using the same vocal mimicry to attract prey - but not yet recorded by scientists - also deserve investigation."
