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

We have a HALLOWEEN drill lesson(the U.S.Military might benefit from viewing this) on how hundreds of thousands of Brazilian Free-Tailed Bats simultaneously emerge every Summer evening in the Hill Country(Austin/San Antonio region) of Texas from their single limestone cave without nary occurring a casulty------great 7 minute video for you to enjoy and digest

Bat Ballet: Slo-mo footage reveals how thousands of bats emerge from a cave without injury

Every summer evening, deep in the Hill Country of central Texas, hundreds of thousands 

of Brazilian free-tailed bats (Tadarida brasiliensis) pour from the mouth of a limestone 
cave. The pungent smell of guano and the rush of sound and air from so many wings 
beating at once is an experience that truly
overwhelms the senses. Then, just like that, 
it’s over—in a matter of minutes, members
of the entire colony have emerged from the 
cave and disappeared into the dusk for their
 nightly foraging flight.
To the naked eye, in real-time, the colony
exodus is a blur of wings and bodies moving 
too fast to track. Yet somehow, the entire
colony manages to exit the cave, night after
 night, without traffic jams or (many)
 casualties. How do they achieve this incredible 
feat? Scientists Nickolay Hristov and Louise
Allen set out to answer this question. 
Using high-speed video cameras, they have
 captured these events — and
 interactions among individual bats — in
spectacular detail. Now, frame by frame, 
they are discovering that it’s not always
necessary for nature to come up with 
the perfect solution — just one that’s
good enough.
