The Ohio Department of Natural Resources is investigating the death of dozens of birds found Saturday along Interstate 680 in Youngstown.

Passers-by spotted the carcasses of large black birds along the north bound lane near Midlothian Boulevard.

ODNR Wildlife Officer Jesse Janosik told 21 News that he would take photographs of the dead birds and collect samples for testing.

Janosik says he expects it will take a couple of days before it is determined what caused the animals to die.

According to the Division of Wildlife website, ODNR actively follows up on reports of any wildlife diseases in Ohio and monitors the health of wildlife populations to ensure their long-term conservation.

The ODNR Division of Wildlife website lists several diseases affecting birds including Avian Flu, West Nile Virus and Conjunctivitis.

There is no indication if any of those diseases played a part in the death of these birds.
