While most Western Pennsylvanians look forward to that harbinger of spring — the return of songbirds to local fields, forests and backyards — the migration can be harmful to poultry.

Russell Redding, state Department of Agriculture secretary, reminded poultry owners to protect their birds from the highly pathogenic avian influenza, which is commonly known as “bird flu.”

“The best line of offense is a strong defense,” Redding said. “Poultry producers should review and use strong biosecurity practices as part of their daily routine to protect their flocks, as well as Pennsylvania’s $7.1 billion poultry industry.”
