"Experts urge bird flu vaccination to protect endangered species and prevent pandemic"

Birds in the US are facing multiple threats, including habitat loss, disease, and climate change. Over 3 billion birds have been lost since 1970, and dozens of species are considered endangered, threatened, or at risk. The California condor, whooping crane, and island scrub-jay are among the birds with the lowest populations. Climate change is exacerbating the threats to birds, with nearly three-fourths of the nation's birds vulnerable to losing large parts of their range. Conservation efforts are needed to protect these important species and the broader environment.
