Robert Mesa will be leading our Guided Bird Trail Walks. He recently retired as an ornithologist with the U.S. Fish and Wildlife Service. He spent his professional career working to protect, conserve, and recover threatened and endangered North American bird populations. His area of expertise is the recovery of endangered birds of prey. He directed national and international-level programs to recover the California condor, bald eagle, peregrine falcon, and the masked bobwhite quail. Robert coordinated the California Condor Recovery Program from 1990 to 2000. In 1992, he directed the first reintroduction of captive-bred condors back to the wild in southern California and in 1996, he led the successful release of condors into the Grand Canyon. In the 1980's Robert established the highly successful Arizona Bald Eagle Nest-Watch Program and was a member of the National Bald Eagle Recovery Team that down listed the Bald eagle from endangered to threatened in 1995. As leader of the National Peregrine Falcon Recovery Team, he wrote the rule that removed the peregrine falcon form the Endangered Species List after its successful recovery. As leader of the Masked Bobwhite Quail Recovery Team Robert worked to establish a captive breeding and release program in Mexico to re-establish this endangered sub-species to its historical range in Sonora, Mexico. From 1999 to 2015 he coordinated the Sonoran Joint Venture, a bi-national bird conservation program between the United States and Mexico.
