- It was a pure coincidence.
We came driving when the first one ran across the road and then I picked up the phone.

See when the roosters start fencing
He has seen crazy capercaillie roosters in the wild before - but never when they have rumors together.
- It was really cool and a spectacle in high school, says Nicklas Öderyd.
In the clip above, you see when the capercaillie roosters smoke together.
