Geographic Range
East Caucasian turs (
Capra cylindricornis
) are found along the Greater Caucasus mountain range. The eastern part of their
range is well defined by Babadagh Mountain in Azerbaijan, but the western boundary
is less definite. The southern portion of their range extends to the area of the headwaters
of the Inguri River. In the north, the species ranges to Bezengi Cherek River or
perhaps to the headwaters of the Malka River in the Elbrus Mountain massif. The total
length of the range of the East Caucasian turs is about 500 km, if measured to Benzengi
Cherek River. The distribution has changed little since the 19th century, when it
was slightly wider, encompassing peripheral mountain ranges, more distant from the
Main Watershed Range and the Side Range.

Habitat
Capra cylindricornis
is found at elevations from 1,000 to 4,000 m, in forest, and alpine areas. However
areas over 3,500 m are rarely visited. East Caucasian turs migrate from lower elevations
during the winter into higher elevations during the summer. Females prefer to live
in the forests whereas males prefer to live in the open grasslands.

Physical Description
Capra cylindricornis
displays marked sexual dimorphism in size, pelage and horn development. Females have
a body length of 138 cm, shoulder height of 85 cm, and, weight of 56 kg. Males have
a body length of 190 cm, shoulder height of 104 cm, and weight of 140 kg. The tail
length is 11 to 15cm for both sexes.
The coat in males varies seasonally, from chestnut-brown with lighter underparts in
the winter to an overall lighter rusty-brown color in the summer. The coat of females,
juveniles, and yearlings is the same year round.
East Caucasian turs have a body that is thick and stout and supported by short legs.
Like most goats, a beard is found on males and is most noticeable when these animals
display their winter pelage. Unlike other goats, the skull of East Caucasian turs
does not have a bulge on the forehead below the horns. The horn base is cyndrical,
and the horns curve up and out from the forehead and then slightly down and inward
curling at the tips. Female horns grow to 20 to 22 cm whereas males grow to 70 to
90 cm in length.
East Caucasian turs differ from other species of Caprids by having much shorter beards.
They also lack the stripes on their forelegs that are typical of Siberian ibex, Nubian
ibex, and wild goat.
The winter color of male
C. cylindricornis
is brown, helping to distinguish them from males in other populations of
Capra caucasica
, which are grayish-yellow at that time of year. Alpine ibex (
Capra ibex
) are also similar to
C. cylindricornis
. These animals have a similar color coat and a short beard, but can be easily distinguished
from
C. cylindricornis
by differences in their horns. West Caucasian turs (
C. caucasica caucasica
) are smaller and less massive than East Caucasian turs (
C. caucasica cylindricornis
).

Reproduction
East Caucasian turs breed seasonally in December or January. Males and females live
separtedly except during the breeding season when males come down from the higher
elevations to breed. Adult males fight furiously against each other for access to
females. Females can also be violent during this time, chasing younger males away
if they try to breed. Young males do not attempt to breed until after adult males
have done so.
- Mating System
- polygynandrous (promiscuous)
East Caucasian turs breed in December or January, depending on where they are located
in the species range. Females give birth to one and rarely two young per breeding
season. The gestation period is 150 to 160 days. The young begin to eat grasses in
July. Weaning begins in December, by which time the young have been grazing for several
months.
Age of sexual maturity in males is between four and six years. Females are sexually
mature by four years of age, however yearling females may also breed.
Females isolate themselves before birth and keep their young hidden for 3 to 4 days
after birth. Females form incoherent groups of approximatedly a dozen individuals.
Home ranges of males overlap those of females, but males are highly territorial with
other males during the breeding season.

- iteroparous
- seasonal breeding
- gonochoric/gonochoristic/dioecious (sexes separate)
- sexual
- fertilization
- viviparous
As is the case for most mammals, parental care is primarily a female occupation.
Mothers provide their young with milk, grooming, and protection. Time to weaning
is 2 to 3 months, but young stay with their mother for about a year. Male parental
care has not been reported for this species.

Lifespan/Longevity
East Caucasian turs live up to 15 years in the wild and up to 22 years in captivity.
Behavior
East Caucasian turs have seasonal migrations in which they alter their elevation
by 1,500 to 2,000 m. They move up the mountain slopes following retreating snow in
March and descend to low slopes in August. Males generally are solitary and inhabit
higher elevations with more open areas than do females. Females prefer lowland forest
areas.
In summer feeding occurs at intervals in late afternoon, night, and morning with the
goats spending the hot hours of the day resting in sheltered places. In winter, herds
remain in open pastures throughout the day grazing and resting.
There are three basic types of social units in this species. Females are found
in groups with young, but there are also young male groups, and solitary males. Males
are found with females only during the rutting season. Group sizes are usually around
ten individuals, but group size fluctuates with precipitation levels.
East Caucasian turs have a hierarchical order in which adult males dominate younger
males during the rut. Young males dominate females year-round, and females dominate
yearlings and juveniles.
- Key Behaviors
- terricolous
- diurnal
- crepuscular
- motile
- migratory
- solitary
- social
- dominance hierarchies
Home Range
The size of home ranges is 4 to 6 square km for female groups. Males have a larger home range.
Communication and Perception
East Caucasian turs have a variety of vocalizations. They have an alarm call that
is a sharp and hissing whistle. Also females and kids bleat to each other. Males
mark areas during the rutting season by debarking trees by rubbing their horns on
the trunk and marking by rub against the bare place with postcornal area. These markings
do not appear to be territorial, but only for identification purposes. LIke other
mammals, there is tactile communication during agonistic encounters, as well as between
individuals in a reproductive context.
- Other Communication Modes
- scent marks
Food Habits
East Caucasian turs graze primarily on grass and shrubs. Grasses are eaten in autumn
and begining of winter. Low shrubs such as
Vaccium myrtillus
are essential to East Caucasian turs in winter.
Euonymus
,
Pinus
,
Rosa
, and
Salix
are preferred browse.
- Plant Foods
- leaves
- roots and tubers
- wood, bark, or stems
Predation
Young East Caucasian turs mature quickly and are able to run soon after birth. East
Caucasian turs live in groups to help protect them from predators. They do not appear
to have a very good alarm call. The alarm call is a sharp hissing whistle that is
hard to hear. Natural predators include wolves.
Ecosystem Roles
East Caucasian turs are herbivores that change the floral composition and diminish
productivity of their feeding areas. They also use mineral licks. East Caucasian
turs share their range with
Chamois
and may be the limiting factor in this species range. They appear to be sympatric
with red deer.
As a prey species, C. cylindricornis is likely to influence populations of its predators.
Capra cylindricornis provides habitat for a variety of parasites. They are known to be infected by tapeworms, flukes, 29 species nematodes, lice, ticks, and larvae of gadfly.
Economic Importance for Humans: Positive
Traditional use of hide and wool has been abandoned, but horns of East Caucasian turs
are still valuable and widely used. The horns are used for home decoration and are
often mounted in silver as traditional cups for wine and beer.
- Positive Impacts
- food
- body parts are source of valuable material
- ecotourism
Economic Importance for Humans: Negative
East Caucasian turs compete with livestock raised by the local people.
- Negative Impacts
- crop pest
Conservation Status
East Caucasian turs are listed as vulnerable in IUCN. This is due to habitat destruction,
and over hunting.
Other Comments
Fossil remains of East Caucasian turs are mentioned, but not described, from Late
Pleistocene deposits from Caucasus Minor. It is unlikely that these are actually
of
C. cylindricornis
, since its range does not include Caucasus Minor. However, if they are of this species,
it would indicate that historically the range of the species differed from the current
range.
