Physical
Description
The Sika
deer is a rather elegant looking animal. They have strong solid
bodies which are carried on long slender legs. The head is small
and is carried by a short but bulky neck. The Sika deer is similar
in stature to the Red Deer, but is slightly smaller in size. Males
Sika Deer are commonly known as Stags, and the Females as hinds.
There
can be considerable variation in the colour of the coat. But typically
during the summer animals have a dark chestnut brown colour upper
coat, this is marked with 7 or 8 rows of white spots. The undersides
and lower neck and throat are white in colour. During the winter
the coat is longer and thicker, the coat becomes darker and the
spots are not as clearly visible. The winter coat is moulted in
early spring in April or May and regrows again in the late Autumn.
Both sexes
have a distinctive large white rump patch, which is surrounded
by a rim of black fur. This can be puffed out to signal when danger
is near. On the head there are white markings on the chin and
lips. The insides of the ears are white, but there is also a large
black 'thumbprint' marking that is distinctive in this species.
Sika Deer have a remarkable whistle like call, and can often be
heard whistling softly to each other.
Males
grow antlers for use in the autumn breeding season. Fully-grown
males grow antlers which have a total of 8 tines. The antlers
are usually a pale brown or even a white colour. The antlers are
lost each spring, but new ones begin to grow immediately. Younger
males may not grow a full complement of antlers until they reach
maturity.
Distribution
Originally
the Sika deer was distributed in eastern Asia, being found in
Vietnam, Japan, Taiwan, the Ussuri area Russia, and the Chinese
province of Manchuria. The Japanese subspecies of Sika Deer were
introduced in to Europe in the 19th Century as parkland deer,
subsequently escaping and in some places forming wild herds. 5000
are thought to be wild in Europe, with a much greater number being
found in parks. In Europe they are found in the countries of Britain,
Ireland, Poland, Czech Republic, Denmark, Germany, Austria and
Russia. They are found only in scattered location in Europe, but
in Asia they have a more widespread distribution. They have also
been introduced into New Zealand and the USA.
Habitat
The preferred
habitat of the Sika Deer is deciduous or mixed woodland, especially
that which has a good under story of vegetation. This type of
habitat provides it with a good variety of foods from which to
feed on. However, they are also found in a number of other types
of habitat. They will also inhabit areas of young coniferous woodland,
especially where there are many open clearings and glades.
Lifespan
In captivity
Sika deer can live to be over 20 years of age, but in the wild
such high ages are seldom reached. In the wild animals will be
lucky to reach 7 years of age.
Diet
The Sika
Deer feeds on a variety of woodland plants and grasses. They will
feed on more herbaceous plants than the Red Deer.

Breeding
In Europe the
breeding season or rut for Sika Deer takes place between
September and November. Sika Deer can increase there populations
rapidly, this is because many females conceive each year
and because in fact mortality is relatively low when compared
with other species of deer.

The rut
is a time of much activity for Sika Deer. At the beginning of
the rut animals move to traditional rutting grounds, and here
males compete with each other for small breeding territories.
The fighting between males is typically highly ritualised. The
males in possession of the best territories are able to collect
together the greatest number of females and thus mate the most.
The young
are born after a gestation period of about 220 days long, with
a single fawn usually being born, typically between May and June.
At birth the young weigh from 4.5 to 7 kg. They are a dark brown
colour, with numerous white spots, these disappear as the winter
coat grows and cannot usually be seen after about 3 months of
age. The young lie hidden in concealed vegetation for the first
2 to 3 weeks of their life, before beginning to accompany their
mother. The young leave their mother shortly before the birth
of their next young. The males go to join male bachelor herds,
while the females form small groups.
Behaviour
The Sika
Deer is a social herd living animal. However, it's the social
structure of its herds can vary at different times of the year
and in different locations. The males live either in small bachelor
groups, or live solitary single lives. The older males tend to
be more solitary in behaviour than younger animals. Females live
in small herds with their young. Sometimes mixed herds may occur.
The Sika deer is mostly active at dusk and dawn, resting during
the middle part of the day and at night.
