Tribal effort to fix broken world hinges on condor (AP)

in this photo taken on Friday, Aug. 7, 2009, Yurok Tribe wildlife biotechnician Tiana Williams holds a turkey vulture in the hills above Orick, Calif., where it was trapped as part of the tribe's efforts to determine if the Klamath River canyon would be suitable habitat for condors. Lead poisoning is the leading cause of death in condors in the wild, and the tribe is taking blood samples to see if the turkey vultures are feeding on carcasses shot by lead bullets. The tribe's culture is based on the idea of regularly trying to fix what is wrong with the world, and bringing back the condor is part of that belief. (AP Photo/Jeff Barnard)AP - The tribes of the lower Klamath River have since ancient times decorated themselves with condor feathers when they performed the dances designed to heal a world gone wrong.
