Have you ever heard of a capercaillie? This random video quickly sent me to Wikipedia where I now know:

It’s a heavy member of the grouse family and the largest of all extant grouse species. Found across Europe and the Palearctic, this primarily-ground-dwelling forest grouse is renowned for its courtship display. This bird shows extreme sexual dimorphism, with males nearly twice the size of females.

The word capercaillie is a corruption of the Scottish Gaelic capall coille which means “Horse of the wood”. [source]

That’s the beautiful thing about the Internet. You can encounter a random video like this and then immediately learn something new and wonderful about the world 🙂
