"The great migration began perhaps 40 years ago. From strongholds in the Rocky Mountains and Texas, young males headed east, seeking female companionship and new places to settle."
"The emigrants were about seven feet long, nose to tail, and weighed up to 160 pounds. Given a dietary choice, they preferred deer, but would eat almost anything that moved: elk, bighorn sheep, wild horses, beaver, even porcupines. Left free for an evening, they were capable of killing a dozen domestic sheep before dawn, eating their fill and leaving the rest for the buzzards. They were also known to attack humans on occasion.
Long ago the Inca called them puma, but today — though they belong to only one species — they have many names. In Arizona they are known as mountain lions; in Florida they are panthers, and elsewhere in the South they are called painters. When they roamed New England, they were called catamounts. In much of the Midwest they are known as cougars, and that is the name everyone understands."
