Description

The male fallow deer is known as a buck, the female is a doe, and the young a fawn. Adult bucks are long, in shoulder height, and typically in weight; does are long, in shoulder height, and in weight. The largest bucks may measure long and weigh .Burnie D and Wilson DE (Eds.), ''Animal: The Definitive Visual Guide to the World's Wildlife''. DK Adult (2005), Fawns are born in spring around and weigh around . Their lifespan is around 12–16 years. Much variation occurs in the coat colour of the species, with four main variants: common, menil,

). * Common: Chestnut coat with white mottles, it is most pronounced in summer with a much darker, unspotted coat in the winter. The light-coloured area around the tail is edged with black. The tail is light with a black stripe. * Menil: Spots are more distinct than common in summer and no black is seen around the rump patch or on the tail. In winter, spots are still clear on a darker brown coat. *

, which are broad and shovel-shaped (palmate) from three years. In the first two years the antler is a single spike. They are grazing animals; their preferred habitat is mixed woodland and open grassland. During the rut bucks spread out and females move between them; at that time of year fallow deer are relatively ungrouped compared with the rest of the year, when they try to stay together in groups of up to 150. Agile and fast in case of danger, fallow deer can run at a maximum speed of over short distances. Being naturally less muscular than other cervids such as the roe deer, they are not as fast. Fallow deer can also jump up to high and up to in length.


History

(NSW) was precluded for some years by the classification of these deer as "game animals", as well as being a feral pest species. This led to an explosion in numbers, a vast increase in range in that state, impacts on agricultural production, increased environmental damage, and a dramatic increase in vehicle accidents involving deer. This policy has since been reversed on privately held land only, and on such land the deer is once again only classified as a feral pest species; they remain game animals on public land. The NSW government now asks the public to assist by ''not'' transporting or releasing feral deer onto any land, implying that intentional release of deer has been a factor in the vast increase in range in NSW in recent years.

''Ethology'', ''83''(3), 195–214. . Different populations, environmental variation, size, and even age can determine the type of variation within a European fallow deer mating system, but lekking behaviour is the most commonly found and studied in nature; variation can be explained by three characteristics (1) the optimal strategy under specific environmental or social conditions, (2) the strategy of an individual may be dependent on the strategies of other individual males within the same population, and (3) individual males may be less capable at gaining access to females, since they can be outcompeted by other males that are more capable.

Ecology and mating system characteristics

Many deer species—including European fallow deer—have a social organization that can be tremendously plastic depending on their environment, meaning that group size and habitat type are closely linked to herd size.Putman, R. J. (1986).
Grazing in temperate ecosystems: Large herbivores and the ecology of the New Forest
'. Croom Helm: Beckenham.
Most of the detailed research on the ecological characteristics and behaviour of European fallow deer occurs in large blocks of woodland, which means some bias may be present. European fallow deer can be found in a variety of habitats, which can range from cool and wet to hot and dry. European fallow deer seem to have a preference for older forests with dispersed areas of grass, trees, and a variety of other vegetation. The largest herd occurs right before the rutting season, while the smallest groups are females with fawns. Throughout a large portion of the year, the sexes remain separated and only congregate during the mating months, but other patterns may be described, such as bachelor groups and even mixed groups. Male European fallow deer produce low-frequency vocalizations called groans; the sound of these groans results from the consistent and complex shape of the vocal tract involving the oral and nasal cavities. Ruts are characterized by males gaining the best territory possible to increase their odds for mating, and are often characterized by the presence of females on stands. During this time, males stop feeding to defend their ruts from subordinate males. Males defending this territory often lose an average of 17% of their body weight, and the liver exhibits
steatosis Steatosis, also called fatty change, is abnormal retention of fat (lipids) within a cell or organ. Steatosis most often affects the liver – the primary organ of lipid metabolism – where the condition is commonly referred to as fatty liver disea ...
, which is reversible. Throughout breeding seasons, the males may obtain the same rut; in some cases, ruts can be held by more than one individual; some possibilities for this include high population density and less rut space, or more suitable habitats, which can be shared.


Parental care

After a female is impregnated, gestation lasts up to 245 days. Usually one fawn is born; twins are rare. The females can conceive when they are 16 months old, whereas the males can successfully breed at 16 months, but most do not breed until they are 48 months old. The females can become very cagey just before they give birth to their fawn and find secluded areas such as a bush or cave; sometimes females give birth near the herd. As soon as the female gives birth, the she then licks the fawn to clean it; this helps initiate the

; males do not participate in rearing the fawn. After the birth of the fawn occurs, the females do not return to the herd for at least 10 days and for most of the days the mother is separated from the fawn, returning only to feed the fawn. The nursing period lasts about 4 months and happens every 4 hours each day. Rumination is a critical part of development in the fawn's life, and this develops about 2 to 3 weeks into the fawn's life. Females initiate the

periods for the fawn, which lasts about 20 days; 3 to 4 weeks; later, the fawn will start to follow its mother, and they will finally rejoin the herd together. The mother frequently licks the fawn's anal area to stimulate suckling, urination, and defecation, which is a critical part of the development of the fawn. Weaning is completed at around 7 months, and at around 12 months, the fawn is independent; after the 135 days of reproduction, the rut comes to an end, which can be characterized by the changes in group size and behaviour.


Contests and weaponry

Since European fallow deer are polygynous species that congregate once every year, males must fight to obtain access to estrous females.Bergeron, P., Festa-Bianchet, M., von Hardenberg, A., & Bassano, B. (2008). Heterogeneity in Male Horn Growth and Longevity in a Highly Sexually Dimorphic Ungulate. ''Oikos'', ''117''(1), 77–82. . . The relationship between antler size and body condition can be treated as indicators to reflect body condition within a given year.Ciuti, S., & Apollonio, M. (2011). Do Antlers Honestly Advertise the Phenotypic Quality of Fallow Buck (''Dama dama'') in a Lekking Population? ''Ethology'', ''117''(2), 133–144. . These secondary sexual characteristics can have dual functions, which include the attractiveness of males, which females can ultimately choose, and fighting ability of the male.Darwin, C. (1859). ''

Sexual selection
'. Princeton University Press, Princeton, New Jersey
It was found that males with larger antlers had higher mating success, where males with asymmetrical antlers did not. When males develop their antlers, trade-offs always are made between reproduction and survival, which can shape the decision in an individual's choice. Genetic variations exist within fallow deer populations with variable antler growth, males that exhibited faster-growing antlers early in life are able to grow longer antlers without any significant cost; this shows that there is, in fact, phenotypic variation among fallow deer populations. Aggressive behaviour is often observed when individuals are seeking out mates, scarce resources, and even territories.Jennings, D. J., Boys, R. J., & Gammell, M. P. (2017). Weapon damage is associated with contest dynamics but not mating success in fallow deer (''Dama dama''). ''Biology Letters'', ''13''(11), 20170565. . Species that compete using their weapons usually engage with mutual agreement, but if any noticeable asymmetries are seen, such as a broken or lost weapon, this may alter the behaviour of an individual to engage in a fight. Likelihood and severity of antler damage were looked at in fallow deer, to test whether antler damage was associated with contest tactics and duration, and if an association existed with the tendency for individuals to engage in fighting. Individuals with undamaged antlers were more likely to attack, using high-risk tactics that included jumping, clashing, or backward-pushing behaviour, this was exhibited by both contestants; dominant males were more likely to have damaged antlers. Dominance ranks exist within fallow deer populations, which can be linked to aggression level and body size; when competing for a male, however, how ranks are obtained is not studied extensively.Jennings, D. J., Carlin, C. M., Hayden, T. J., & Gammell, M. P. (2010). Investment in fighting in relation to body condition, age and dominance rank in the male fallow deer, ''Dama dama''. ''Animal Behaviour'', ''79''(6), 1293–1300. .


Endurance rivalry

Male fallow deer are highly competitive during the rutting season; successful mating depends mainly on body size and dominance rank.McElligott, A. G., Gammell, M. P., Harty, H. C., Paini, D. R., Murphy, D. T., Walsh, J. T., & Hayden, T. J. (2001). Sexual size dimorphism in fallow deer (''Dama dama''): Do larger, heavier males gain greater mating success? ''Behavioral Ecology and Sociobiology'', ''49''(4), 266–272. . . Many factors can determine the seasonal reproductive success of an individual male fallow deer; these factors include body size, which can affect reproduction and survival. The amount of time spent in a lek can be an important factor in determining male reproductive success; energy can play an important role for the duration of competitive leks.Craig, A. S., Herman, L. M., Gabriele, C. M., & Pack, A. A. (2003). Migratory timing of humpback whales (''Megaptera novaengliae'') in the central North Pacific varies with age, sex and reproductive status. ''Behaviour'', ''140''(8), 981–1001. . . Among ungulates, European fallow deer exhibit one of the most outstanding examples of sexual dimorphism, as males are much larger than females. For sexual selection to lead to the evolution of sexual dimorphism, where males are bigger than females, advantages must be present: (1) Advantages during combat, (2) Endurance rivalry advantage, (3) Female preference for larger males, and (4) Advantages during sperm competition. Sexual selection has chosen bigger males over an evolutionary time scale and conferred advantages during competition of mates by a variety of mechanisms, which are intrasexual competition, access to females, and resource accessibility, which affects attractiveness to females. Body size is important during male-male agonistic interactions and endurance rivalry, while females tend to have a preference for larger males.Alonso, J. C., Magaña, M., Palacín, C., & Carlos, M. A. (2010). Correlates of male mating success in great bustard leks: the effects of age, weight, and display effort. ''Behavioral Ecology and Sociobiology'', ''64''(10), 1589–1600. . . Dominance rank is a good indicator of body size and body mass, but age was not an important factor. In a study done by McElligott et al. (2001), it was found that mating success was related to body size, pre-rut and rut rank. Similarly, in another study, researchers found that age, weight, and display effort were all significant factors in determining mating success; in both studies, mating success was measured by the frequency of copulations, which means that a variety of factors in different fallow deer populations can affect the overall energy allocation which will ultimately affect mating success. Maternal investment early in life can be critical to the development of body size, since it can be quite variable at that stage depending on resources and habitat type. Mature male body size can be a better indicator of overall male quality rather than body mass, since body mass depends on a variety of resources each year and is not a static trait; body mass can be a complex trait to measure.
