Chester Zoo in the UK received quite the surprise recently. One of their Bornean orangutans had a baby on June 18 despite a number of pregnancy test results coming back negative.
Sky reported primate keeper Chris Yarwood, who works at the zoo, as saying: “The pregnancy tests we had carried out on Leia in the months prior to the birth had actually returned negative results. It was therefore a wonderful surprise to arrive one morning and see her protectively cradling a beautiful new arrival.”
