A gorilla was born Friday to two members of a group assembled at the National Zoo to increase the population of the endangered species.

Mandara, a 9-year-old western lowland gorilla, gave birth to a full-term infant in the early morning hours, the zoo said. The last gorilla birth at the zoo occurred in 1972. "At this time, mother and newborn are doing well," the zoo said in a statement.Mandara and the father, 10-year-old Augustus or "Gus," belong to five-member group living at the zoo's Great Ape House.
