(Portland, OR) -- The first critically endangered California Condor hatched at the Oregon Zoo turns 20 years old this week. Kun-Wac-Shun, or, number 340, hatched at the zoo's Jonsson Center for Wildlife Conservation on May 9th, 2004. Since 2005, he has been flying free over Central California's Pinnacle National Park, where he is one of the most dominant males in the flock. He has fathered five wild-hatched chicks, including the first condor to fledge from its nest at Pinnacles in more than a century. In 1982, only 22 remained in the wild. Thanks to recovery programs like the Oregon Zoo's, the Condor population has rebounded to more than 500.
