I didn’t even know turkeys used sleeping bags…
Gobbling Down of course.
Here’s the 2011 deer hunting results from Michigan (where I formerly lived):
http://www.michigan.gov/documents/dnr/WLD_report3548_2011_deer_harvest_survey_report_390798_7.pdf
45% of hunters harvested a deer in 2011, compared to 44% in 2010.
It is very hard to get a handle on. My state (NM) really tries, and requires harvest reports for all licenses issued, but there are factors that distort the data. Deer licenses must be applied for and paid by April 1, for fall hunts.
Between April and fall lots of shit can happen, and a significant fraction of those that draw licenses won’t hunt at all, and some may only hunt a weekend. You lose your job and have to sell your camper and rifle so you can’t go hunting. A deadline at work means you can’t take time off. A forest fire destroys the area where you drew the tag.
Next “Deer” is not one species. There are several in the US, but Whitetails in the East and Mule Deer in the west cover the majority. Mulies and Whitetale have very different habits, habitats, and require far different tactics. The more open woods of the west mean that both hunters and deer can see a lot farther, and also means the sparser vegetation can support fewer deer.
One thing for sure, though, all deer are easier to bag than elk. (Wapiti) A spooked deer runs over the next ridge. A spooked elk doesn’t stop 'till he is in the next county.
Snipe are notoriously difficult to bag.
In what used to be prime Whitetail habitat we have an abundance of Wolves. Don’t get me wrong, wolves are beautiful animals, but they are also a Fierce Preditor.
As was told to us 40 years ago by the wildlife management folks, “the wolf will enhance the Deer herd”. Well that has happened and what it typically means is there are no more dumb, old, or otherwise easy to hunt deer. Yes there are deer in the deep forests but the abundance are close in around farms and city’s.
We here in MN just finished the first Wolf hunt and aprox 411 wolves were taken. This was a very conservative target number so as not to effect the population but allow some of the excess to be harvested.
So our deep forest deer camps will still find very dificult hunting.
As an example, 40 years back I would pick up a deer track in the later part of the season mostly as early season too many hunters doing deer drives and I never liked that kind of hunting, but I would jump a deer 3-4 times in just a couple of hours of stalking that deer and sometimes I would get a good shooting opertunity. In this enhanced deer herd, when I pick up a track I can stalk that deer all day and not get a glimps of it. Yes my eyes are not what they used to be, but the deer are much jumpy’r and having to learn to survive everyday life with Hungary wolves, well us two legged preditors are very inept. 
One guy I know used to live in Michigan. Hunting season for him usually lasted about a half hour. Get up early, drive to father in law’s farm, drive to a pasture, wait 10-15 minutes and shoot a deer.
The deer weren’t baited in or anything, they just liked that particular place and nobody else hunted that farm.
