The European Fallow Deer, Dama dama, is a medium-sized deer with a widespread presence. Originally native to Eurasia, particularly Turkey and potentially parts of the Italian Peninsula, Balkan Peninsula, and Rhodes, its distribution expanded significantly due to human activity over millennia.
Distinctive Physical Characteristics
European Fallow Deer exhibit a variable appearance. Adults typically range from 1.3 to 1.7 meters in body length, with males, known as bucks, standing 85 to 95 centimeters at the shoulder and weighing between 60 to 100 kilograms. Females, called does, are slightly smaller, measuring 75 to 85 centimeters in shoulder height and weighing 30 to 50 kilograms.
Their coat displays four primary color variations:
- The “common” variant features a chestnut coat with white mottles in summer, which becomes a darker, unspotted grey-brown in winter.
- Menil deer possess more distinct spots year-round on a paler background.
- Melanistic individuals are very dark, sometimes appearing black.
- Leucistic fallow deer are cream-colored as fawns and turn pure white as adults, though they are not albinos as their eyes retain a normal dark color.
A defining feature of male European Fallow Deer is their broad, shovel-shaped, or palmate, antlers. These antlers begin as single spikes in the first two years of a buck’s life and develop their characteristic flattened shape from around three years of age, growing up to 70 centimeters in length. Antlers are shed annually, typically in April, and regrow, becoming free of velvet by August.
Habitat, Diet, and Social Structure
European Fallow Deer inhabit a wide range of environments, from cool, humid regions to warm, dry areas. They generally prefer mixed woodland and open grassland, particularly older forests with dispersed grassy areas and varied vegetation. Human introductions have extended their presence across much of Europe and other continents.
The diet of European Fallow Deer is flexible, adjusting to seasonal availability. They are primarily herbivores, grazing on grasses, herbs, and leaves during spring and summer. In autumn, their diet shifts to include acorns and other mast, while winter foods consist of shrubs like brambles, bilberry, holly, and ivy, as well as bark and coniferous material. Feeding activity often peaks at dusk and dawn, though they may forage throughout the day.
Fallow deer are social animals, typically forming groups, though their social structure can be quite fluid depending on the environment. Outside the mating season, sexes usually remain separated, with females and their fawns forming groups and males congregating in bachelor herds. These groups can be quite large, sometimes numbering up to 150 individuals, particularly before the rutting season.
Reproduction and Lifecycle
The European Fallow Deer’s reproductive cycle centers around an annual rutting season, primarily from early October to early November. During this time, male deer, known as bucks, establish “rutting stands” or territories, which they defend against rivals. Bucks engage in distinctive behaviors, including producing loud, deep “groans” or “belches” to attract females and advertise their presence and condition. They also thrash vegetation and paw the ground to mark their territory.
Females are receptive to breeding from about 16 months of age. Males can breed successfully at 17-24 months. After successful mating, gestation lasts approximately 231 to 245 days, or 33 to 35 weeks. Usually, a single fawn is born in late spring or early summer, typically in June or July, though twins can occasionally occur.
Fawns weigh around 3 to 4.5 kilograms at birth and are initially hidden in dense vegetation by their mothers, who return periodically to nurse them. Weaning typically begins around 20 days and can continue for several months, with fawns becoming more integrated into the herd with their mothers after about three to four weeks. The average lifespan for European Fallow Deer is 12 to 16 years.
Fallow Deer in Human Landscapes
European Fallow Deer have a long association with human populations, frequently maintained in parks and estates for their aesthetic appeal and as game animals. Their historical presence in places like Britain dates back to Roman times, and their reintroduction by later groups, such as the Normans, highlights their cultural significance over centuries.
Managing fallow deer populations involves balancing conservation with control measures, especially given their widespread distribution and ability to increase in numbers. While considered of “Least Concern” by the IUCN Red List due to their overall abundance, specific populations, such as the Rhodian fallow deer, are genetically distinct and require conservation efforts. In some areas, large populations can lead to ecological impacts, including damage to vegetation and competition with native cervids. They can also be involved in deer-vehicle collisions, posing risks to both human safety and incurring economic costs.
