The National Zoo's Conservation and Research Center announced yesterday that the clouded leopard cubs born last month are both male.

The sex of the cubs, born March 24, could not be determined until their first veterinary examination. Both weigh about 19.5 ounces and have opened their eyes. More than 70 clouded leopards have been born at the research center in Front Royal, Va., since 1979. The previous litter was born in 1993.

Hannibal and Jao Chu, the father and mother of the cubs born last month, were imported from Thailand last year.

The births were the first in the official North American clouded leopard zoo population in six years. The zoo, part of the Smithsonian Institution, has 14 clouded leopards: two at the zoo in Washington and 12 at the research center. The cubs have not been named.
