chamois

The chamois, Rupicapra rupicapra, is a goat-antelope species native to mountains in Europe, including the Carpathian Mountains of Romania, the European Alps, the Gran Sasso region of the central Italian Apennines, the Tatra Mountains, the Balkans, parts of Turkey, and the Caucasus. The chamois has also been introduced to the South Island of New Zealand. Some subspecies of chamois are strictly protected in the EU under the European Habitats Directive.
There are two species of chamois in the genus Rupicapra: R. rupicapra (the type species) is replaced in the Pyrenees and in the Apennines by the Pyrenean chamois, R. pyrenaica. The chamois (along with sheep and goats) are in the goat-antelope subfamily (Caprinae) of the family Bovidae.
 
The English name is from the French chamois. This is derived from Latin camox, borrowed from Gaulish, itself perhaps a borrowing from Iberian or Aquitanian, akin to modern Basque ahuntz, "goat".
 
The usual pronunciation for the animal in English is SHAM-wah, approximating the French pronunciation. However when referring to its leather (and in New Zealand often for the animal itself) it is pronounced SHAM-ee, and sometimes spelt "chamy". As with many quarry species, the plural is the same as the singular.
 
The Dutch name for the chamois is gems, and the male is called a gemsbok. In Afrikaans, the name "gemsbok" came to refer to a species of Subsaharan antelope of the genus Oryx and this meaning of "gemsbok" has been adopted in English
Chamois live at moderately high altitudes and are adapted to living in steep, rugged, rocky terrain. A fully grown chamois reaches a height of about 75 centimetres (30 in) and weighs between 20 kilograms (44 lb) and 30 kilograms (66 lb). Both males and females have short, straightish horns which are hooked backwards near the tip. In summer, the fur has a rich brown colour which turns to a light grey in winter. Distinct characteristics are a white face with pronounced black stripes below the eyes, a white rump and a black stripe along the back. Chamois can reach an age of 20 years.
 
Female chamois and their young live in herds; adult males tend to live solitarily for most of the year. During the rut (late November/early December in Europe, May in New Zealand), males engage in fierce battles for the attention of unmated females. An impregnated female undergoes a gestation period of 20 weeks, after which a single kid is born. The kid is fully grown by 1 year of age.
 
Alpine chamois arrived in New Zealand in 1907 as a gift from the Austrian Emperor, Franz Joseph I. The first surviving releases were made in the Aoraki/Mount Cook region and these animals gradually spread over much of the South Island.
 
In New Zealand, hunting of chamois is unrestricted and even encouraged by the Department of Conservation to limit the animal's impact on New Zealand's native alpine flora.
 
New Zealand chamois tend to weigh about 20% less than European individuals of the same age, suggesting that food supplies may be limited.
As their meat is considered tasty, chamois are popular game animals. Chamois have two traits that are exploited by hunters. The first is that they are most active in the morning and evening when they feed. The second trait is that chamois tend to look for danger from below. This means that a hunter stalking chamois from above is less likely to be observed and more likely to be successful.
 
The tuft of hair from the back of the neck, the gamsbart (chamois "beard"), is traditionally worn as a decoration on hats throughout the alpine countries. Chamois leather is very smooth and absorbent and is favored in cleaning and polishing because it produces no streaking.
 
The European Roe Deer (Capreolus capreolus), also known as the Western Roe Deer or chevreuil, is an Eurasian species of deer. It is relatively small, reddish and grey-brown, and well-adapted to cold environments. Roe Deer are widespread in Western Europe, from the Mediterranean to Scandinavia, and from the British Isles to the Caucasus. It is distinct from the somewhat larger Siberian Roe Deer.
 
English roe is from Old English raha, from Proto-Germanic *raikhon, cognate to Old Norse ra and German Reh. A 5th century runic inscription on a roe deer ankle bone found in England (the "Caistor-by-Norwich astragalus") transliterates as raïhan, thought to refer to the deer itself. Ultimately, the word may be drawn from the proto-Indo-European root *rei-, meaning "streaked" or "spotted."
 
The Roe Deer is distinct from the somewhat larger Siberian Roe Deer (Capreolus pygargus) that is found from the Ural Mountains to as far east as China and Siberia. The two species meet at the Caucasus Mountains, with the European species occupying the southern flank of the mountain ranges and adjacent Asia Minor and the Siberian species occupying the northern flank of the mountain ranges.
 
Within Europe, the European Roe Deer occurs in most areas, with the exception of northernmost Scandinavia (north of Narvik) and some of the islands, notably Iceland, Ireland, and the Mediterranean Sea islands; in the Mediterranean region it is largely confined to mountainous regions, and is absent or rare at low levels. Scottish roe deer were introduced to the Lissadell Estate in Co. Sligo in the Republic of Ireland around 1870 by Sir Henry Gore-Booth, Bt. The Lissadell deer were noted for their occasional abnormal antlers and survived in that general area for about 50 years before they died out and there are not believed to be any roe deer currently extant in Ireland.
 
German colonial administrators introduced Roe deer to the island of Pohnpei in Micronesia. They are hunted by locals in very steep and heavily vegetated terrain. The meat is openly sold in markets and restaurants in Kolonia, the capital city of Pohnpei and the Federated States of Micronesia.
 
The Roe Deer is a relatively small deer, with a body length of 95–135 cm (3.12–4.43 ft), a shoulder height of 65–75 cm (2.13–2.46 ft), and a weight of 15–30 kg (33–66 lb). It has rather short, erect antlers and a reddish body with a grey face. Its hide is golden red in summer, darkening to brown or even black in winter, with lighter undersides and a white rump patch; the tail is very short (2–3 cm or 0.8–1.2 in), and barely visible. Only the males have antlers. The first and second set of antlers are unbranched and short (5–12 cm or 2.0–4.7 in), while older bucks in good conditions develop antlers up to 20–25 cm (8–10 in) long with two or three, rarely even four, points. When the male's antlers begin to regrow, they are covered in a thin layer of velvet-like fur which disappears later on after the hair's blood supply is lost. Males may speed up the process by rubbing their antlers on trees, so that their antlers are hard and stiff for the duels during the mating season. Unlike most cervids, roe deer begin regrowing antlers almost immediately after they are shed.
 
The Roe Deer is primarily crepuscular, or primarily active during the twilight, very quick and graceful, lives in woods although it may venture into grasslands and sparse forests. It feeds mainly on grass, leaves, berries and young shoots. It particularly likes very young, tender grass with a high moisture content, i.e., grass that has received rain the day before. Roe deer will not generally venture into a field that has had or has livestock (sheep, cattle) in it because the livestock make the grass unclean. A pioneer species commonly associated with biotic communities at an early stage of succession, during the Neolithic period in Europe the Roe Deer was abundant, taking advantage of areas of forest or woodland cleared by Neolithic farmers
The Roe Deer attains a maximum life span (in the wild) of ten years. When alarmed, it will bark a sound much like a dog and flash out its white rump patch. Rump patches differ between the sexes, with the white rump patches heart-shaped on females and kidney-shaped on males. Males may also bark, make a low grunting noise or make a high pitched wolf-like whine when attracting mates during the breeding season, often luring multiple does into their territory. The Roe Deer spends most of its life alone, preferring to live solitary except when mating during the breeding season.
 
The polygamous Roe Deer males clash over territory in early summer and mate in early fall. During courtship, when the males chase the females, they often flatten the underbrush leaving behind areas of the forest in the shape of a figure eight called 'roe rings'. Males may also use their antlers to shovel around fallen foliage and dirt as a way of attracting a mate. Roebucks enter rutting inappetence during the July and August breeding season. Females are monoestrous and after delayed implantation usually give birth the following June, after a ten-month gestation period, typically to two spotted fawns of opposite sexes. The fawns remain hidden in long grass from predators until they are ready to join the rest of the herd; they are suckled by their mother several times a day for around three months. Roe deer adults will often abandon their young if they sense or smell that an animal or human has been near it. Young female roe deer can begin to reproduce when they are around 16 months old.
 
The world famous deer Bambi (the eponymous character of the books Bambi, A Life in the Woods, and its sequel Bambi's Children, by Felix Salten) is originally a roe deer. It was only when the story was adapted into the animated feature film Bambi, by the Walt Disney Studios, was Bambi changed to a white-tailed deer. This change was made due to the white-tail being a more familiar species to the mainstream U.S. viewers. Consequently, the setting was also changed to a North American wilderness.
