Daniel Bieber, a German photographer, in the skies over Costa Brava,
Spain, was able to photograph an amazing phenomenon called mumuracy,
when thousands of starlings are gathering in a huge flock creating
amazing images in the sky.
A huge number of starlings created a figure of a huge bird in the sky.
The photographer himself believes that in this way the starlings reacted
to the appearance of a predatory hawk near the pack and in response to
the threat created the image of a giant bird of a frightened predator.
