July 13, 2005. Tucker, at bottom, a baby Siamang, was born June 27 at the Fort Wayne Children�s Zoo to mother Penny. The baby weighed an estimated 6 ounces at birth and will grow to 30 pounds as an adult. Tucker�s birth was not without suspense; zookeepers were uncertain how Penny�s delivery would go. At age 26, she and mate Gus, 27, are considered �old to become parents,� zoo staff said. Though Tucker is her fourth offspring, Penny last gave birth nearly 20 years ago. Tucker will spend most of the next few months riding on his mother�s belly or back. Visitors can see Tucker and his parents in their exhibit along the Indonesian Rain Forest area�s Tree Tops Trail. Siamangs, which are endangered in the wild, live in the rain forests of Indonesia and Malaysia. The zoo is open 9 a.m.-5 p.m.
