The dead birds were within a span of 50 feet of roadway, the Springfield News-Leader reported.
Kailey Frayer, who lives near where the birds were found, said she first noticed the birds about 11:30 a.m. Saturday.
"They weren't there when I left, and an hour later, they were all there," she said.
Frayer said she lived in the area about two years and this is the first time they have seen anything like this.
"It's a curiosity," said Ellie Mason, who lives nearby.
