Hundreds of birds found dead on a north Wales road are to be tested to discover how they died.

About 225 starlings were discovered with blood on their bodies in a lane on Anglesey, North Wales Police said.

Dafydd Edwards, whose partner found the birds, said it was as if "they had dropped down dead from the sky".

The Animal and Plant Health Agency has collected them for testing and will examine whether they could have been poisoned.

North Wales Police said it was investigating the "very strange" discovery and has appealed for information.

"We don't know how it has happened," said PC Dewi Evans.

Mr Edwards, 41, said his partner Hannah Stevens first saw the birds alive as she went to an appointment on Tuesday afternoon.

"She said she saw hundreds of them flying over and thought it looked amazing but on her way back around an hour later they were all dead in the road.

Ms Stevens reported seeing the birds eating something in the road.

"I counted 150 last night but I gave up as there's just hundreds of them littered everywhere.

"It's as if they just dropped down dead from the sky."

A spokesman for the RSPB said: "This is obviously very concerning for us and we will await the test results.

"It would be inappropriate for us to speculate as to how they have died."
