One problem for the deer - - which are too numerous - - are the black bears. Here in Pike County, PA on the same 90 acres three bears were taken during this past hunting season, but only one deer. A couple of miles away, 11 black bears were removed from a fish hatchery.
The PGC's studies have shown that as of a couple of years ago, black bears were killing as many fawns as coyotes.
When you have creatures that need 20,000 calories a day in the fall to bulk up before hibernation, meat is probably less of a hassle than getting 70 lbs of blueberries for the same calorie count.
To paraphrase Willie Sutton: "[I rob banks] 'cause that's where the money is".
