Like human, animals at the Oklahoma City Zoo are enjoying milder temperatures as fall arrives.
Ruben, a young chimpanzee who arrived at the zoo in July, took a stroll around his enclosure Tuesday, playing in the tall grass. His surrogate mother, Siri, enjoyed some time swinging from a rope.
Bogie, one of the zoo's giraffes enjoyed some lettuce for his lunch Tuesday while outside.
The zoo is open from 9 a.m. to 5 p.m. daily.
