Avian flu kills 3 critically endangered California condors in Arizona as virus exposure increases during spring migration

The California condor flock will increase exposure to avian flu as they migrate north this spring, threatening the survival of this critically endangered species.
Three California condors among a population ranging across northern Arizona and southern Utah have already died from avian flu, with five others being tested for infection.
California condors were nearly driven to extinction due to hunting, habitat loss, and lead poisoning but have since slowly recovered to over 400 birds.
Conservation groups warn the avian flu outbreak poses a major threat to the condor's long-term recovery.
