have restricted this species to a number of isolated populations, many of which are on private lands in Kansas, Colorado, Oklahoma, New Mexico, and Texas. Small population size, changing habitat resulting from drought, and climate change threaten continued survival.

California Condor • Once reduced to nine individual wild birds, this raptor is slowly recovering, thanks to captive breeding and the release of individuals in California and Arizona. There are now 305 individuals, including 148 free-flying birds. Lead bullets are a critical threat to long-term survival, as fragments poison wild condors that eat the remains of hunters’ kills. Audubon California and American Bird Conservancy have spearheaded recent passage of legislation eliminating lead bullets in the range of the condor in that state.
