An unnamed donor has contributed $1 million to the San Francisco Zoo to build a home for its aging chimps.
The zoo wanted to improve the great ape habitat for its three most senior members, but did not have the funds. The $1 million is a solid jump start to the drive to raise $10 million.
The chimps are called Cobby, Minnie and Maggie and live at the San Francisco Zoo. At 57, Cobby is among the oldest in captivity anywhere.
Those who want to donate can do so on the zoo's website.
