Amur tigers have no natural predators, except man.
Who has driven them almost to extinction.
He eats with growing discomfort.
Something's not right.
Normally, these graceful giants are hunters not scavengers.
But, the won't pass up an opportunity.
It's not easy turning down a free lunch
especially to crows.
Heckling crows call unwanted attention.
Poached every year for their skins and for Chinese medicine.
400 amur tigers remain in the wild.
