Photographer Daniel Biber caught some spectacular sunset images showing murmurations of starlings. In the most remarkable of these, the murmuration itself looked like a starling.
He's rebuilding his site, but in the meantime, there's more information at LensCulture.
Also, via The Independent:
But Mr Biber said he only realised his luck once he reviewed the photographs on his computer. He said: "I was taking pictures of the murmurations over several days. Only when I checked the pictures on the computer later, I realised what formation the starlings had created."
