Like the referenced article says, hunting in England was mostly sport for the landed gentry, but in North America the availability of open land and wide distribution of firearms made hunting a 'primary means of survival.'
Thomas Jefferson's observations about the value of hunting and rambling about with firearms, rather than violent activities like playing ball, probably indicate hunting being viewed as sport. And, there is this recorded observation about TJ as a sporting, not subsistence, hunter:
Isaac Jefferson, in his inimitable Memoirs of a Monticello Slave, gives a clear picture of Jefferson the hunter. He recalls that Jefferson hunted "squirrels and partridges; kept five or six guns...Old Master wouldn't shoot partridges settin'. Said 'he wouldn't take advantage of 'em' - would give 'em a chance for thar life. Wouldn't shoot a hare settin', nuther; skeer him up fust."[4] Isaac goes on to say that when Jefferson heard hunters down in his deer park at Monticello he "used to go down thar wid his gun and order 'em out."
Maybe the gentry of the United States who had some wealth tended to look at hunting as sport, whereas poor folks looked on hunting as necessary to put food on the table and money from meat and hides in their pockets.
