Cheetah yawn

A young cheetah yawns while soaking up the morning sun in an enclosure at the Wildlife Safari zoological park in Winston, Ore., on Saturday, Feb. 2, 2013. The park, which features a drive-through zoo design, has one of the western hemisphere's most successful cheetah breeding programs. 

Since the park began breeding cheetahs in the 1970's 171 cheetahs have been born at the park. Native to Africa, cheetahs are an endangered species with only about 10,000 living in the wild.
