Roan
Antelope Update
continued from main page
After
arriving at Fossil Rim they underwent a 60-day quarantine. Now they can
be seen in the pasture near our offices where one of the females
gave birth to a son on June 11th. They will remain in this pasture
for a while longer so we can more closely monitor their diets and
give the baby a chance to get more comfortable before turning them
out into the front pasture where they will live. If you look closely
you might catch a glimpse of them in the pasture just after you
pass 'Magnum', our Ankole /
Watusi / Scottish Highland bull who can be seen behind the front
entry.
The mature
females of a herd establish a dominance hierarchy among
themselves through extensive fighting, and the highest-ranking
individual
initiates most herd movements, even in the presence of the adult
male. Females are capable of producing a calf every 10 to 10 1/2
months. Their gestation period is about 9 months. Once born, the
young will be kept hidden for around 10 days. The head and body
length is1,880 to 2,670 mm, shoulder height is 1,000 to 1,600 mm
and weight
I 150 to 300 kg. Males are typically one-fifth larger and heavier
than females. They are a pale, reddish brown color with white under
parts. The skin is thick and tough and both sexes possess stout,
heavily
ringed horns. Their ears are about the same size as their horns,
which led the first Europeans to spot these hearty animals to believe
they had four horns.
Roan
are active early in the morning and late in the afternoon and feed exclusively
on grasses and herbs. If
disturbed, they utter
a
snorting sound before fleeing. Roan will go down on their 'knees'
when they fight. This relatively shy animal is among the relatively
few horned ungulates which, when pursued, will stand their ground
and defend themselves with their horns. Where not persecuted,
these antelopes are not extremely wary, often running a short distance
and then stopping to look back. When closely pursued, however,
they can run as fast as 57 km/hr with great endurance. When wounded
or
cornered, they become savage, charging and using their horns
with
amazing speed and dexterity. |
