The Pennsylvania Wildlife Futures Program issued an alert in June 2021:
“Nestling and fledgling songbirds – mainly blue jays, starlings, and common grackles, but also robins and cardinals – have been found with ocular and neurologic issues, and in some cases these birds have been found dead in large numbers.”
“Numerous reports have been received across the United States including the Mid-Atlantic region, extending into the Southeast and eastern upper Midwest. Affected birds were first reported in mid-May in Washington, DC.”
