MENLO PARK, Calif. — After proliferating globally, a historic wave of avian flu has entered Southern California, where it is worrying farmers and bird lovers and could add to complications with supply chains and food prices.
Already, poultry operations have had to euthanize domestic flocks of chickens and turkeys, while thousands of wild birds have also died. Wildlife experts say they are seeing a wave of dying birds moving south — already as far as Irvine — as the fall migration sets in.
Authorities describe the surge as "unprecedented" in scope, breadth and lethality.
