WATCH: Migrating birds create magnificent formations

- It's an amazing sight: Hundreds of thousands of migrating starlings in the skies over Denmark.

Bird watchers flock to watch the massive group of birds that make magnificent formations in the sky in a phenomenom called, "black sun."

"Right now in the highlight from end of September to the beginning of October, we have around 800,000 starlings in one sleep-over, right here," says nature expert Anja Kjolby.

The birds usually make the formations when birds of prey are on the attack.

More than a hundred thousand people visit the national park every year to get a bird's eye view of the spectacular show.
