Rudi was born at the Gladys Porter Zoo in Brownsville, Texas in 1977. He's lived at the Houston Zoo since he was 6 months old, and is now the oldest male orangutan in North America. He loves to play peek-a-boo under a sheet, and is shy around female keepers. He loves the color pink. Sumatran orangutans are known for their high intelligence and sensitivity. Habitat destruction is their battle, due to deforestation from palm oil plantations.
