The Pittsburgh Zoo & PPG Aquarium on Friday announced the birth of a 13th baby to Margaret, one of the oldest breeding female howler monkeys in the country.
The baby, Linc, was born Feb. 27 and joins mother and older brother Cliff on exhibit at the Tropical Forest Complex.
Linc weighs about 1 pound and will remain with his mother for the next several months as long as he nurses and grows, said keeper Karen Vacco.
Visitors may have a hard time seeing Linc at first, Ms. Vacco said, because he is small and clings to his mother's side.
Howlers, a threatened species, have an average life span of 20 years.
