The Roe deer is now among our most familiar deer species, a common sight in woodland, farmland and even gardens across the UK. The Roe's current population boom is remarkable considering that it was considered extinct in all but a few wooded areas of Scotland during the 1700s. Indeed, all current English populations of Roe are believed to be descended from introductions. This small to medium-sized species of deer is one of only two cervids found in the wild that are native to Britain, the other being the Red deer.
That which follows is a brief summary of Roe deer natural history. The detailed article for this species will follow in due course. Certain aspects of the natural history common to all deer (e.g. antler growth and formation, collisions with vehicles, chronic wasting disease) have been split from the individual overviews and placed into their own QA – this is partly to avoid repetition but also to allow more detailed coverage of the topics. A summary of the more general aspects of the biology, ecology and behaviour of Britain’s deer species can be found in the Deer Overview.
The Roe deer at a glance
Originally thought a single species with a European and Siberian subspecies, the Siberian Roe deer is now considered a separate species, Capreolus pygargus.
Size: Adults between 95cm and 1.3 m (3 – 4 ft) long; males (bucks) stand 64 to 67 cm (2 ft) at shoulder. Weight between 15 to 35 kg (33 – 77 lbs).
Colour: Colour variants are occasionally found. Piebald animals (sandy brown with large white patches) have been recorded in Yorkshire and Norfolk and a white (non-albino) doe in Somerset during 2010. Melanistic (black) individuals are rare, albeit locally relatively common in Germany.
Distribution: Common (native) throughout UK (except Ireland) and Europe except Iceland, northern Scandinavia and Mediterranean Islands; range extends east to Asia. Apparently absent from areas of the midlands and Wales. Population increase estimated at ca. 2.3% per year; current (2008) population estimated at 800,000+, making it the most numerous deer species in Britain.
Longevity: Ave. in wild 5 to 7 years, with max. wild of about 12 yrs. Max. age of 20 yrs (in captivity).
Sexing: Males have antlers, which grow to max. ~30cm with 3 tines per antler typical; antlers grown in winter and shed during autumn. Sexed by shape of rump patch; females (does) have tail-like mass of hair at the base of tuft (called the “tush”), bucks don’t.
Antler Cycle: Antlers cast October-December (peak in November) and re-grown during winter; velvet shed mid-February/March.
Activity: Feed throughout day and night, but peak of activity is crepuscular. Long periods where deer “lie up” to ruminate.
Habitat: Spend much of time in shelter of woodland or upland areas; will move to long grass and shrubby undergrowth for browsing; make more use of open spaces at night. Found in farmland.
Territory: Maintain exclusive territory during mid-July to mid-August (rut), may begin establishing territories during late May. Home range varies with season and sex (5 to 100 ha / 12 – 247 ac.). In good habitat defended territory ave. ~ 7 ha (non-territorial males ave. ~15 ha / 37 ac.); does ave. ~7 ha (17 ac.), which overlaps with related individuals.
Diet: Herbs, bramble, tree shoots, flowers and ivy. Some evidence that food selected based on nutritional value.
Reproduction: Rut runs from mid-July to mid-August (peak around 7th August), although can be affected by weather (appears to require warm, humid conditions). Some, more sedate, rutting documented during the autumn (usually mid-Sept. to mid-Oct, but sometimes into December) known as “false rut”. During rut, buck will usually mate with several does. Young (kids) produced after 6 or 7 month (diapause during winter) gestation; peak kid birth in late May/early June. Twins common (ca. 75% births), single kids less common (ca. 20%), triplets occasional (ca. 5%) - up to 5 well-developed foetuses found in does in Italy. Kids lie in grass for first week; suckled for first 2-3 months and independent by following spring (1 year old).
Behaviour and Sociality: Generally solitary; may form groups during winter; does frequently accompanied by kids and home ranges may overlap with other females. Any sociality seems scent-mediated. Bucks may fray trees and shrubs with antler and face glands during the rut. Bark, especially at dawn and dusk, when disturbed – not descriptive of sex, although males tend to bark more than females.
Threats: Hunted for sport in parts of their range, although stag hunting with hounds is now illegal in the UK. Roads can pose threat to deer; people often killed or seriously injured upon collision with deer. Sometimes come into conflict with forestry or private land owners because of the damage they can do to trees and flowers. Study in Sweden found high kid mortality from agricultural mowers. Some evidence that they may be displaced by muntjac (number ~20% lower when Muntiacus present) and less competitive in habitat containing Fallow, Sika and, especially in conifer plantations, Red deer.
