The Père David's deer is endemic to the Chinese region. According to fossil records, the species first appeared during the Pleistocene period, when it could be found anywhere in the Manchuria.[4] This demography changed during the Holocene period; during this time, the species could only be found in the swamp lands and wetlands of southern China. Due to hunting and land reclamation, the demography of the Père David's deer became even smaller. By 1939, the last of the wild species were shot and killed.[5]

Naming and etymology[edit]

Birth and lifespan[edit]

The gestation period is about nine months, roughly around 280 days, after which a single offspring is usually born; twins are born in rare cases. The gestation period is significantly longer than any other deer besides the roe deer. Père David's deer are considered seasonal breeders due to the fact that three out of four calves born during the month of April in captive European populations. The breeding season is 160 days with the mating season usually being in June and July. Calf weight, calculated using Robbins and Robbins equation, tends to be between 11.3 and 13.2 kg. The juveniles (referred to as either fawns or calves) have a spotted coat, as is commonly seen in most species of deer. They are known to develop very quickly after birth. They reach sexual maturity at about 14 months.[8] The average lifespan of a Père David deer is up to 18 years.


To those living in temperate latitudes, Père David's deer has similar reproductive physiological mechanisms. These mechanisms aid in the adaptation to a high latitude environment. The reproductive behavior in stags differs from hinds. In stags rutting behavior includes urine sniffing, anogenital sniffing, wallowing, and antler adorning. Mating behavior includes mounting and copulating. Communication behavior includes the spraying of urine and preorbital gland marking. The stags generally begin to rut prior to any signs of female sexual behavior. The reason to this is to establish a social rank among the stags. For Père David's deer the stag initiates the breeding season with the rutting. In hinds, estrous behavior includes urinating frequently, receptivity, and allowing the stags to mount. Parental behavior involves sniffing the calf, calling, and rubbing the face of the calf. The hind has a typical behavior of being solitary.[9]

In captivity[edit]

An experiment was conducted to show how captivity would affect the deer's behavior and survival rate. Two areas were created; one with a large area containing a few amount Père David's deer present and one with a small area containing a high concentration of Père David's deer present. It was found when in captivity, it is best to keep the deer in large open areas that allow for adequate space with a reasonable number of individual deer living in the area; if put in a small area with a multitude of individuals present, stress amongst the deer will build up. Studies have shown through the high concentration of fecal matter in an area of captivity with limited space and large amount of Père David deer that they have shown different behavioral patterns to their wild counterparts. These deer would spend less time resting, and would stand longer due to human presence as well as display social aggression and competition over food sources. It is therefore unwise to keep them in small, densely populated areas to prevent accumulation of stress and aggression against each other.[10]

The Père David's deer has been in isolation from the wild for more than 1200 years, causing humans to be the primary perceived threat due to a long-term lack of exposure to other natural predators. When encountering humans, the deer's response varies according to gender. Female-only groups display a lower degree of caution towards humans than in male-only groups. It was hypothesized that the presence of a single type of threat may be sufficient to maintain anti-predator responses in the face of relaxed predation pressure. During rutting season, the does will display increased vigilance and heightened threat perception, likely in response to the mating activities of the males .[11]


Historically, the main predators of the Père David's deer are believed to have been tigers and leopards. Despite no longer encountering ancestral predators while living in captivity, while experimenting with exposures to images and stimuli relating to these big cats, the deer seemed to instinctively react with a cautious predator-prey response typical of wild deer.[12]




Extinction in China[edit]

In the late 19th century, the world's only herd belonged to Tongzhi, the Emperor of China. The herd was maintained in the Nanyuan Royal Hunting Garden in Nan Haizi, near Peking.[14] In 1895, one of the walls of the hunting garden was destroyed by a heavy flood of the Yongding River, and most of the deer escaped and were killed and eaten by starving peasants. Fewer than thirty Père David's Deer remained in the garden. Then in 1900, during the Boxer Rebellion, the garden was occupied by troops and the remaining deer were shot and eaten, leaving the Père David's deer extinct in its native China.[1]





In 1993, 30 deer taken from the herd at Beijing Milu Park were released into the Tianezhou Milu National Nature Reserve. These were followed by another 34 deer taken from Beijing Milu Park and released into the Tianezhou Reserve. In a 1998 flood, a number of deer escaped from the reserve and have since been living and multiplying in the wild. As of 2015, the number of deer living in the wild is 700.[17] The average annual population growth rate for Père David’s deer in Tianezhou Nature Reserve was 22.2%.[1]


When the species was assessed for the IUCN Red List (1996), it was classified as "critically endangered" in the wild, under criterion "D": "[wild] population estimated to number less than 50 mature individuals".[18] In October 2008, they were officially listed as extinct in the wild, though this is no longer accurate.[17] Today, there are 53 herds of Père David's deer in China. Nine of the herds consist of 25 or under deer, and the remaining herds have under 10 deer.[19] Due to the small population size a lack of genetic diversity is expected, but in spite of the small population size, the animals do not appear to suffer genetic problems from the genetic bottleneck. The captive population in China has increased in recent years, and the possibility remains that free-ranging populations can be reintroduced in the near future.[1]

When reintroduced into their habitat, the species could face many problems due to years in captivity. Relaxed selection and reproduction with no environmental pressure may have taken place for Père David’s deer, due to captive breeding, which can result in the loss of adaptive anti-predator behavior. It is possible that when fully released in the environment from captivity, after generations of offspring, the species could be unable to retain parasite-defense behaviors like grooming. If the population is reintroduced into the environment with no protection against tick infestation then they can face major problems if not adapted to that environment.[20] Since also no longer being adapted to other predators, such as tigers, it could cause confusion for the Père David’s deer. They could have possibly lost the memories of their ancestral predators. Although, a study was done on the species that are in captivity using the sounds of tigers roaring and dogs barking and the deer did not respond to the barking of the dogs, but hearing the tiger roar caused the deer to spend more time being cautious after hearing the sound. Which shows that the deer still retained memories of their previous predator, the tiger.[21]


Though New Zealand lacked its own native population of deer, European settlers had introduced a numerous number of species of deer into the land for the use of farming and hunting. Some of these deer species had crossbred in the wild, creating hybrids, which in turn were then utilized in deer farms based on their apparent genetic improvements. Alongside this discovery, deer farms began the practice of inciting hybridization in order to encourage genetic advancement. This includes a hybrid between Père David's deer and Red deer. These F1 hybrids are unique for several reasons. To begin with, both male and female offspring of this hybrid remain fertile, a rare prospect especially for species that have such a genetic distance. Both species differ in seasonal behaviors, gestation length, behavioral traits, morphology, maturity size, and disease resistance. Père David's deer is also unique in that its antlers are unlike any other deer in the world.[22] However, due to having different seasonal behavior each species would enter their mating season at different intervals, thus preventing natural mating from occurring. In response, artificial insemination was employed on Red deer hinds with the semen from Père David's deer. These F1 hybrids did not share similar mating seasons with Père David's deer and as such were able to successfully mate with other red deer naturally. Three F1 hybrid stags successfully mated naturally in a period from 1989 to 1991 with 144 hinds and semen had been used to artificially inseminate 114 other Red deer hinds producing over 300 backcross hybrids.[23]

Legend and cultural significance[edit]


According to Chinese legend, when the tyrant King Zhou of Shang ruled the land more than 4,000 years ago, a horse, a donkey, an ox and a deer went into a cave deep in the forest to meditate and on the day the King executed his virtuous minister Bigan, the animals awoke from their meditation and turned into humans.[20] They entered society, learned of the King's heinous acts and wanted to take recourse against the King, who was powerful.[20] So they transformed themselves into one creature that combined the speed of the horse, the strength of the ox, the donkey's keen sense of direction and the nimble agility of the deer.[20] This new animal then galloped to the Kunlun Mountains to seek the advice of the Primeval Lord of Heaven. The Lord was astonished at the sight of a creature that had antlers of a deer, hooves of an ox, face of a horse and tail of a donkey. "It's unlike any of four creatures!" he exclaimed. Upon learning of the animal's quest, Lord gave his blessing and dispatched the creature to his disciple the sage Jiang Ziya, who was battling the King.[20] Jiang Ziya rode the creature to victory over the King and helped found the Zhou Dynasty. After fulfilling its vow, the milu settled in the lower reaches of the Yangtze River.[20] The animal became a symbol of good fortune and was sought by later emperors who believed eating the meat of the milu would lead to everlasting life.[20]
