Zoo officials in San Diego, California, say a giant panda was born at the San Diego Zoo on Tuesday, making it one of only about 10 giant pandas in the United States.
The officials say the mother, a 13-year-old giant panda pregnant with twins, gave birth to one cub, but the other died in the womb.
It is the second panda birth in less than a month at a U.S. zoo.
The first was born three weeks ago at Washington's National Zoo. On Tuesday, veterinarians determined that cub is male. The cub's parents are being loaned by China under a 10-year agreement.
Giant pandas are endangered with a total population of 1,600, both in captivity and in the wild.
