Averill, a 6-year-old male Allen's swamp monkey was introduced to the two other swamp monkeys and four colobus monkeys in the rainforest exhibit. He's from Chicago's Lincoln Park Zoo.

A DeBrazza's monkey, a gerenuk and three Speke's gazelles have new homes in the Savanna exhibit.

The DeBrazza's monkey, a 7-year-old male named Gus, arrived from the Sedgwick County Zoo in Wichita, Kan. He shares an exhibit with the zoo's female DeBrazza's monkey, Debra.

The 2-year-old male gerenuk, named Mr. Brooks, hails from the Oklahoma City Zoo.

Three female Speke's gazelles from St. Louis and Los Angeles joined a male and female already residing in the zoo's Savanna exhibit.

"Our Africa exhibits are bustling with activity," said Oregon Zoo Director Tony Vecchio. "We're excited to have all the new animals, and look forward to even more when Predators of the Serengeti opens next summer.”

Set to open in 2009, Predators of the Serengeti will celebrate African predators large and small, including lions, cheetahs, African wild dogs, red-billed hornbills, dwarf mongooses and caracals.
