Daniel Biber, 53, captured the breathtaking snap after observing thousands of birds and scouting locations over a four-day period.
Like clouds in the sky, the giant flocks often take on weird and wonderful - and sometimes graphic - moving forms and shapes.
And the birds made for a startling spectacle when they assembled over the Costa Brava in northeastern Spain in front of Mr Biber's eyes.
He managed to take a series of images which show the birds merging into the shape of a giant bird when they were targeted by a predator.
And the unique snap has since earned him the top prize in an international photography competition.
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.
