People across Indiana are being urged to take down bird feeders as a mysterious illness continues to spread.
The Department of Natural Resources says reports of sick and dying songbirds have been reported in more than 50 Indiana counties, including Vanderburgh and Gibson.
The DNR says the species most affected are blue jay, robins, grackles, starlings, northern cardinals, and brown-headed cowbirds.
On its Facebook page, the agency says it’s collecting samples and submitting them to the Indiana Animal Disease Diagnostic Laboratory.
The birds have tested negative for avian flu and West Nile virus.
As the investigation continues, the DNR recommends Hoosiers remove their birdfeeders, including those for hummingbirds, to help prevent the illness’ spread.
