TOKYO (AP) _ A giant panda at Tokyo's Ueno Zoo may be pregnant, a zoo official said Monday.

The official, Hiroshi Sugiura, said 13-year-old Huan Huan is showing indications of pregnancy such as a smaller appetite and slower actions. However, he said, ''we haven't confirmed the pregnancy.''

Huan Huan was artificially inseminated on Jan. 31 after she and her companion, 19-year-old Fei Fei, failed to mate earlier that month.

Huan Huan gave birth June 22 - 110 days after being artificially inseminated - but the first panda born in Japan died 43 hours later, accidentally crushed to death by its 220-pound mother.

Huan Huan was presented to the zoo in January 1980 and Fei Fei in September 1982 by China.
