Summary

Bird flu outbreaks in zoos are killing endangered animals, including tigers, lions, and cheetahs, with potentially severe implications for conservation.

The virus is believed to spread from infected wild birds entering enclosures, particularly during migration.

Zoos worldwide have reported closures and deaths, such as a cheetah and kookaburra in the U.S. and dozens of big cats in Vietnam.

Experts emphasize improving biosecurity and considering vaccinations to protect captive animals.

The virus continues to spread globally, affecting wildlife, livestock, and even humans, heightening concerns over its adaptability.
