The mystery of 300 starlings found dead in the middle of a country road in Wales appears to have been solved.
Toxicology tests were conducted on the deceased flock following an investigation by police's rural wildlife team on Anglesey.
Hundreds of the birds were found dead along a road near Bodedern last December, reports North Wales Live.
At the time of the birds' deaths, speculation was rife as to the reason behind their demise, but now the Department for Food and Rural Affairs (DEFRA) has revealed the results of the post mortem examinations on the birds - and they have ruled out several possible explanations.
A spokesman for the Department said: "The laboratory's view is that blunt force trauma is the main cause."
The spokesman added that virology, bacteriology and histopathology tests had all been carried out.
Bird flu had been ruled out and there was "no evidence of infectious diseases”.
The story of the birds' deaths travelled the globe back in December.
Everything from poisoning to disorientation from electronic signals from 5G masts was in contention, as theories abounded on social media.
Police said at the time that the incident that it was a "complete mystery", and during the course of their investigations they heard that it may have happened before on the island.
The rural crime team said that the most likely explanation was that the flock had taken evasive action - probably to avoid a predator such as a bird of prey - and that some of them had slammed into the ground as their murmuration changed course.
A starling murmuration can often comprise thousands of birds.
