Health and environmental officials are currently investigating why around 40 birds fell from the sky in the town of Dorchester, Massachusetts this week.
The strange incident reportedly took place on Thursday morning.
According to the city’s Inspectional Services, a species called a grackle were the only type of birds that appeared to be sick.
As many as 40 birds were found dead, while others were lethargic.
Investigators are also looking at the possibility of the birds ingesting a chemical agent known as avitrol, which is often used to remove pests.
