    A 35-year-old male California condor that has served a pivotal role in returning condors to the skies above California for the past 30 years was returned to the wild on December 29, 2015 by biologists at Bitter Creek National Wildlife Refuge in Kern County, California. The condor, known as AC-4, was captured on August 7, 1985, by a team of U.S. Fish and Wildlife Service (Service) biologists at Bitter Creek National Wildlife Refuge as part of an effort to prevent extinction of the species. He was one of 22 California condors - the last remaining on Earth - captured between 1983 and 1987 to breed in captivity as part of the Service-led California Condor Recovery Program. On December 29, re-branded as California condor number 20, he was released in the same area where he was captured.
