Maned Wolves at Sweden's Nordens Ark Zoo had two pups in late January; one male and two females. The zoo's breeding pair is a key pair in the Maned Wolf breeding program worldwide, making this birth especially important for conservation. Maned Wolf pups are born all black, and gradually change color as they grow older. By around six months of age, they'll be nearly completely reddish brown. The pups will remain close to their mother in their den for now, but by spring visitors should have a chance to see them in person.
