Bucks run off prospective suitors through threatening body postures or engaging in violent jousting contests using their impressive racks as weapons. Exhausted by the rut, many bucks fail to survive the winter. The gestation period for does lasts six to seven months with one or two fawns born in the early summer. Twin births often occur after the first pregnancy. The spotted nursing fawns spend the day hidden in the underbrush while the mother is away.
The youngsters do not have an obvious odor that would give them away to predators. Fawns begin accompanying their mother within a few weeks. Mule deer are commonly seen browsing in open, shrubby areas between dusk and dawn. They browse shrubs, trees and occasional grasses and forbs and retreat to tree cover to bed down during the day. Studies from Specimen Mountain in the park indicated shrubs comprised 73 percent of the animal's diet, with broad-leafed herbs an additional 26 percent.
The first Estes Valley settlers in the early 's found a moderately abundant mule deer numbers. A growing population of people, predators and the often harsh elements took huge numbers of the animals.
No, not quite. Moose, elk and caribou of North America have close relatives on the other side of the Pacific. East Siberian moose are nearly indistinguishable from Alaska moose, and can be considered the same subspecies. Siberian wapiti and North American elk are a bit more different, but still close enough. Caribou covers the whole Arctic area, and have a theoretical opportunity to share their genes across the whole population.
The relationship between these species, however, is as complicated as if they were characters of a Mexican telenovela.
Regular classification has it that whitetail and mule deer are separate species, while blacktail is a subspecies of the mule deer. Genetic tests, however, complicated the picture. From analysis of mitochondrial DNA a piece of genome that the organism inherits from the mother , it looks like the white-tailed deer evolved first as in 3.
Then some part of its population became isolated somewhere on the Pacific coast and evolved into black-tailed deer. Then black-tailed deer began to colonize the continent, met with whitetails, hybridized with them, and the hybrids evolved into mule deer.
For example, the fact that black-tails and mule deer readily mate, while whitetail and mule deer hybrids in the wild are rare. Further studies may result in a different story. That mostly refers to whitetail and mule deer, whose ranges overlap in many parts of the US, Canada and Mexico. An escaping deer raises the tail, and shows a bright flag of white fur, that is used as an alarm signal to other deer. Mule deer can be recognized by its large ears that earned them their name — to early European settlers they resembled those of a mule.
Antlers of the species are also different. Whitetail antlers have one main beam, from which minor points separate — in the typical antler formation it resembles a hair comb. Mule deer antlers fork — that is, each beam is divided into two equally sized points, then each of these points branches again. The species also differ in behavior, which is explained by the fact that they prefer different landscapes.
Behavior and calling in the rut is also different which might explain why they seldom interbreed in the wild. Deer and Lyme Disease. Deer Density and Forest Regeneration. Deer Disease.

The whitetail population fell from about The mule, blacktail , and other deer populations fell from about 4.
Less than 4 million in The recent peak for mule and blacktails was around , illustrated in the graph below for the estimated U. Deer were nearly hunted to extinction by the early s and were extirpated in many regions. In the U. BIological Survey estimated the whitetail population at , Conservation and restocking allowed whitetail populations to recover to about pre-colonization levels while blacktails and mule deer are below historic levels.
The modern decline of mule and blacktail populations has been a major concern of wildlife agencies for decades. The population estimate [ methodology ] is based on information from state agencies and other groups collected on this website, discussed on each state page that can be accessed by clicking on the drop down menus above.
The estimate also relies on harvest data for each state, available using the links at the top of the column at right. A few numbers are unavailable and estimated. Population estimates can have a wide range of reliability. As illustrated in the figure above, the U.
Mild winters in the north and recovery from the Texas drought account for much of the uptick since Some numbers are goals, so population estimates from these states have been adjusted based on harvest data.
Data for the trend in the whitetail deer population from and earlier is based on Kert VerCauteren in The Deer Boom , the Wildlife Management Institute's book " Whitetail Deer: Ecology and Management " and others , updated using current harvest data and state population estimates. Recent University of Wyoming research puts the white-tailed deer population prior to European settlement at 30 to 40 million, so the historic estimate above may be low.
A summary of historic mule and blacktail population estimates. Research published in and [PDF] using data from this site identified the recent change in the total population trend, turning down around the year Causes for the Decline of the Deer Population. Habitat loss, change, and fragmentation are known to play a role in the decline. Many fear that chronic wasting disease will drive the deer population to low levels over the coming decades.
Searching the internet, this site has tracked many of the proposed causes for the declining deer population reported in the column at right and in more detail on for each state on their page, including:. When Europeans first came to settle America, it was estimated that as many as 10 million elk roamed the land. The current population is around one million.
An estimated 1 million moose in North America in The last U. Been in Decline for Many Years. The graph below shows the estimated to California deer population, made up of blacktails and mule deer, falling by about 75 percent from See the California page for an analysis of what appears to be the largest modern decline in the deer population.
Read a peer reviewed research article demonstrating how public management decisions in California may have contributed to the long term decline of the deer population. What Are We Conserving with Conservation? We have outlawed wilderness — can rewilding bring it back? November 11, apolitical. As the grazers were no longer around to keep woody vegetation in check, trees got the upper hand over grasses and forests became the dominant vegetation Herds of females include offspring too.
In this way, they can care and protect offspring from predators. Normally, the size of the female deers is quite larger than males. Females walk with offsprings and relatives of other families. In this way, they are more social than males. Males group size is rather smaller as they herd up for mating and sometimes eating only. For deer farming, it is important to understand deer herd management.
These are both very good for deer herds. It is just a glimpse of herd management techniques. You need to cover it if you are thinking of planning deer farming in your land. White-tailed are also social animals that herd up most of the time in their lives.
The size of the herd may be bigger or smaller depending on factors like the purpose of herding, population of deer, and habitat. Doe-fawn herds : that stay together for protection and care of fawns. In this way, mother does also train fawns what to eat and how to eat. Buck-herd : This type of herd includes only males of ages more than 2years to 4 years.
Size of this herd is rather smaller with only 3 to 5bucks in number They often fight for dominance. Buck-herd is occasional and they will no longer stay in the group during the rut. They will roam around females to find mates.
In winter, deer will again group up to find food sources together. This type of herding will keep them warm in icy winds. In some species of deer like whitetail, males form a separate herd. They would not stay with females and offsprings of under one year. However, the group size of males is very small as compared to the herd of females. In whitetail deer, 3 to 5 males group up together. But they would join the female group during rut fall to choose a mate for them.
Are you a hunter and want to hunt from the herd then use this scent for safe hunting. Choose an animal of your choice and take a shoot! Mule deers are extremely social animals. They form groups in so many generations related to different families.
