Large Bird Hits Motorcyclist and Causes Hard Crash [Video]
We could not tell what kind of bird was this, but all that matters now is the fact that it was large enough to cause the rider to lose balance. Of course, the element of surprise has also played a major role in this case and there is little the rider can be blamed for.
The only thing we could say in such cases is that trying to scout ahead could sometimes reveal potential dangers and offer a slightly bigger chance of remaining upright. Damn you motophobic birds!
