Western Lowland Gorilla

A silverback Western Lowland Gorilla named "Wanto" - born at the Woodland Park Zoo in Seattle. Wanto was hand raised by zoo keepers and slowly introduced to a troop of gorillas at the zoo.

He used to wave at visitors and throw dirt at researchers. I had to duck a few sticks and rocks - he had a good sidearm throwing motion. He also would clap his hands a few times, fold his arms, then sit back and watch the visitors clapping.

Wanto, who sometimes considered himself more human than gorilla because of his early nurturing by park attendants, was born at the zoo Dec. 14, 1976. Wanto's most difficult problem was to gain the acceptance of the Woodland Park gorilla troop. He did not do so until he was 7, according to the Seattle-PI. Read more

Western Lowland Gorilla

Wanto - a silverback Western Lowland Gorilla - giving me the eye. This is one of my favorite primate photos. It's interesting to observe the reaction people have when they see the facial expressions of gorillas. "They look so human."

Brown Capuchin Monkey

Capuchin climbing a tree. These monkeys are also known as tufted capuchins because of the cap of short black hair that forms two ridges or tufts on either side of their crown. The capuchin monkey derives its name from the Capuchin monk, whose cowl the monkey's hair-pattern resembles.

Capuchins are very smart and are sometimes kept by humans. Because they are easy to train, they are see on TV commercials and movies - including the monkey named "Jack" in Pirates of the Caribbean. They have also been trained to help disabled people. Like seeing eye dogs guide blind people, capuchins act as helping 'hands' for quadriplegics.

Their diet includes fruit, seeds, insects, reptiles, birds and small mammals. With the proper nutrition, they can live up to 40 years.

Patas Monkey - Erythrocebus patas

The Patas monkey has long limbs and a lean body. This species is well adapted for terrestrial life (ground dwelling), although they also are able to climb trees to avoid predators. The long tail helps with balance when jumping or sitting. They are very fast for a primate, with a maximum ground speed of ~55 km per hour (34 mph) reported.

Their red-brown and white coloration helps them to hide in the tall grass where they forage for food. Both males and females have a black face with a thin white moustache.

Patas monkeys are found in across central Africa, between the Sahara in the north and the equatorial rain forests in the south.
