Most whitetails that stay within the South are homebodies. They don’t need to deal with the tough winters that pressure deer in different areas of the nation emigrate from their summer season vary to a winter vary every year. Each rule has its exceptions, although, and up to date analysis from Mississippi State College’s Deer Lab exhibits that some Southern whitetails transfer round greater than hunters may count on.
Utilizing a GPS collar, researchers with the Deer Lab have been monitoring one buck particularly that swims throughout the Mississippi River twice a 12 months as he migrates from Mississippi to Louisiana and again once more. Often known as Buck 140, the deer travelled 18 miles throughout the winter of 2021, crossing the Large Muddy to get to Louisiana. The buck stayed there till late summer season when he made the trek again to Mississippi. Whereas he adopted the identical actual route this 12 months, Buck 140 isn’t the one deer within the examine that has proven this type of conduct.
“[Some of] these deer are behaving like a northern migratory deer,” says Luke Resop, a graduate pupil at Mississippi State College and one of many researchers within the Deer Lab examine. “In Michigan or Northern Pennsylvania or New York, deer will go from their summer season vary to their winter vary the place they will get higher thermal cowl from snow and discover sources. Clearly, we don’t have actually extreme winters within the South, however we’re noticing some deer nonetheless do these issues.”
The College is at the moment conducting two research on whitetails within the Magnolia State. One is going down within the South Delta, the place Buck 140 lives for many of the 12 months, whereas the opposite is positioned additional north within the state’s CWD zones. Each are trying intently at deer motion patterns as a way to assist the Mississippi Division of Wildlife, Fisheries, and Parks higher handle whitetail populations. The 2 research will wrap up someday this fall.
Responding to Looking Strain and Environmental Situations
Researchers say there are a number of the reason why deer within the South may journey lengthy distances regularly. One issue that earlier research have checked out—and one that almost all deer hunters can agree with—is the connection between searching stress and deer actions.
“Grownup bucks do reply to searching stress and keep away from areas that hunters occupy,” says Steve Demarais, a widely known deer ecologist and professor at MSU who’s main the Deer Lab’s analysis staff. “We’ve documented when and the place hunters have been and checked out when and the place deer have been based mostly on their GPS areas. We [found] that wherever hunters have been throughout the daytime, bucks usually weren’t.”
Demarais explains that bucks in these research tended to maneuver out of those closely hunted areas throughout the daytime and return at night time. These non permanent actions may pale compared to the seasonal migrations from public to personal land that animals make in Utah and different Western states, however they present how shortly deer can adapt to predators on the panorama.
“It is sensible. They discovered to keep away from danger. It matches ecological idea that when prey are uncovered to predators, they study fairly shortly,” Demarais says.
There are, in fact, different components apart from searching stress that may trigger deer to maneuver. Going again to the seasonal migrations which might be widespread amongst Northeastern and Western deer populations, Mississippi’s South Delta area won’t get a lot snow, nevertheless it does flood regularly. This leads Demarais and different researchers to imagine that seasonal floods might be sufficient motivation for deer like Buck 140 to journey lengthy distances every year.
The continued research help their present idea, which is that whitetail deer usually tend to be cell once they inhabit areas with frequent high-water occasions. Curiously, the deer that frequently migrate don’t simply depart one space when it floods. As an alternative, they’ll transfer to at least one space throughout the late winter or early spring, which is when flooding usually happens, after which they’ll return to their core are in late summer season in preparation for the rut. This motion happens throughout each moist and dry years.
Though the Deer Lab’s research are the primary to make use of GPS collars to point out this seasonal conduct amongst whitetails within the South, Resop says that earlier analysis within the state additionally supported this idea. In an earlier examine that was carried out close to the Large Black River in 2020, a deer often called Buck 27 traveled roughly 13 miles to get to a secondary house vary throughout flooding season. Round a 3rd of the deer sampled in that examine behaved equally.
“We have been beneath the belief that this was simply an outlier for this one area of Mississippi,” Resop says. “We didn’t have any good information to recommend that it utilized on a broad scale throughout [the state] till this more moderen undertaking that features Buck 140.”
Each Inhabitants Wants Pioneers
Because the Deer Lab can also be monitoring whitetails within the northern a part of the state, the place floods are much less of a problem, they’re able to examine and distinction the 2 populations. What they’ve discovered is that not one of the GPS-collared deer within the northern a part of the state bear migrations just like the one which Buck 140 has undertaken the previous two years in a row. Throughout that point, almost all the collared whitetails in northern Mississippi have stayed inside a house vary of roughly 800-1,200 acres.
“The cell deer in these areas are simply hardwired to maneuver whether or not the realm floods or not,” says Resop, including that Buck 140’s pilgrimage throughout the Mississippi River and again isn’t even essentially the most spectacular of all of the deer they’ve tracked within the South Delta.

“We’ve bought one doe now. She makes Buck 140’s actions seem like a child’s playtime,“ Resop says. “He’s going 18 miles, and she or he went about 35 miles this previous 12 months.”
A remaining takeaway from the Deer Lab’s ongoing examine is that each wildlife inhabitants depends on some people to take dangers and pioneer new areas. These deer have a tendency to find new areas when stressors improve, Demarais explains, which might open up new territory for whitetail populations and be certain that the species thrives no matter situations in a single particular space.
“Each species of animal, together with people, has to have a number of danger takers,” Demarais says.
