- PHOTO TAKEN 06NOV03 - A worker gives food to a pair of white-winged guans in a cage in a protected area in Olmos, northern Peru, November 6, 2003. A quarter of century ago, Peru's white-winged guan, a species native only to this Andean bird paradise, was considered as dead as a dodo. [Discovered in 1877 by a Polish ornithologist, it was believed extinct for 100 years until its rediscovery in 1977 by Gustavo del Solar, a hunter-turned-conservationist who founded a special breeding project to reintroduce it to the wild.]
