The dead starlings in Beaumont Road, Ladybridge
Between 20 and 30 dead starlings appeared in Beaumont Road, near the Britannia Hotel, on Sunday afternoon.
Eyewitnesses reported hearing a loud bang before finding the birds in an "X-Files-like" experience, as if they had "fallen from the sky".
The Royal Society for the Protection of Birds has said it is unlikely they flew into a poisonous air trail as their injuries would be less uniform.
A spokesman said the low-flying birds, which tend to travel in a tight flock, could have been hit by a vehicle or been confused or dazzled and flown into one.
Craig Clarkson, aged 39, who was in Beaumont Road shortly after the birds first appeared, said there were nearly 100 of them, with some lying still alive in the road.
The RSPB spokesman said: "I have heard of a previous discovery of a group of dead starlings, and it was never really established how they got there.
Comment: This was probably the result of another overhead meteor explosion, where the shockwave killed the birds through blunt force trauma. Incidentally, this was photographed in England on the same day:
