Sumatran rhino to give birth in zoo
CINCINNATI (AP): Seven-year-old Emi could become the first
Sumatran rhinoceros in 108 years to give birth in captivity.
"The confirmed pregnancy at the Cincinnati Zoo is a milestone
of epochal significance for the survival of this venerable
species," said Tom Foose of the International Rhino Foundation.
Zoo Director Ed Maruska announced Emi's pregnancy on Thursday.
The last recorded pregnancy of a Sumatran rhino in captivity was
at the Calcutta Zoo in 1889.
There are only 18 of the animals in captivity -- 15 in Asia and
three in Cincinnati, including Emi, who is on loan from the Los
Angeles Zoo, and Ipuh, the father. An estimated 200 to 400 live
in the wilds of Myanmar, Malaysia, Kalimantan and Sumatra.
Emi's due date is in January or February 1999, after a 15- to
16-month gestation. Weight at birth could be 13 to 18 kilograms
(30 to 40 pounds).
Sumatrans are small rhinos, 1.5 meters (5 feet) tall at the
shoulder and weighing 725 to 900 kilograms (1,600 to 2,000
pounds). They are the only species of rhino with hair -- stiff,
reddish-colored hair that is particularly dense along the back
and on the ears. They have two short horns.
Experts say the breed's march toward extinction is
accelerating. The population has declined 50 percent since 1987
because their rain-forest homes are being lost to logging, and
their horns are treasured for their perceived medicinal
properties, Maruska said.
Conservationists think that the species can be saved only
through captive breeding. "Emi is the last hope," said Mike Dee,
mammal curator at the Los Angeles Zoo.
Sumatran rhinos lead such solitary lives that they come
together only when the female is in heat. Encounters at any other
time end in vicious fights.
The problem facing the Cincinnati zoo was how to tell when the
female was in heat. Staffers solved the problem by taking
ultrasounds three to seven times a week since February to view
Emi's ovaries. By seeing follicles grow and ovulate, they could
plot the reproductive cycle.
