One of Arizona’s most famous birds, the masked bobwhite quail was saved from extinction by the Endangered Species Act.
By the early 1900s, the masked bobwhite was feared extinct. Occasional sightings continued through the early 20th century, and a population was found in the wild near Sonora, Mexico in 1964.
In 1985, Arizona’s Buenos Aires National Wildlife Refuge, containing approximately 118,000 acres of savannah grassland in the Altar Valley, was created for the masked bobwhite. It contains the only population of the birds in the United States.
