These two wood grouse are fighting for territorial rights. One of them should have been watching for eagles.
The capercaillie or wood grouse is common to northern Europe and west-central Asia. Males will battle over breeding rights; battles that seem to take all of their attention.
They’re also a food source for golden eagles, as you’ll see.
That first grouse is one hard-core badass. Even after watching his rival go down to this eagle, it doesn’t stop him from wanting to fight somebody. Even the eagle.
Still, I get the sense that if that eagle was willing to let go of his prize, the brave grouse would be lunch as well.
A bird in the hand is better than one tough guy in the bush.
