"U.S. officials on Tuesday announced the emergency use of a bird flu vaccine to protect the California condor, a critically endangered and magnificent animal that has already bounced back once from the brink of extinction.
After finding a California condor dead from highly pathogenic avian influenza, or bird flu, in March, the U.S. Fish and Wildlife Service sought help from the U.S. Department of Agriculture. Since then, at least 13 condors with bird flu have died, USDA said in a press release.
The deaths, all near the Arizona-Utah border, are alarming considering the world population of California condors was estimated at 561 at the end of 2022, including 347 free-flying birds in three western states and Mexico and 214 in captivity, according to the U.S. Fish and Wildlife Service."
