(Portland, OR) -- The Oregon Zoo has welcomed a new rare African bontebok calf. He was born to eight-year-old "Winter" in the Zoo's Africa Savanna area. The bontebok, which is related to the antelope, is arguably the first African animal saved from human-caused extinction after it was hunted almost to extinction in the 18th and 19th centuries. The calf, now weighing about 18 pounds, won't venture outside to greet visitors until he's a little older. and the weather gets a little warmer.
