Southwest California Condor Flock HPAI Updates 2023

Free-flying California condors in Arizona continue to be confirmed with Highly Pathogenic Avian Influenza (HPAI). To be as transparent as possible to the public and stakeholders about the potential extent of this outbreak, until further notice, the Service will disclose and report all deceased condors in the Southwest Flock found on or after March 30, 2023, prior to necropsy and preliminary testing. As results are confirmed at the U.S. Department of Agriculture’s National Veterinary Service Laboratory we will report them as "confirmed HPAI."  For the latest updates, visit our HPAI webpage.
