About
The western capercaillie, also known as the Eurasian capercaillie, wood grouse, heather cock, cock-of-the-woods, or simply capercaillie, is a heavy member of the grouse tribe 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. The bird shows extreme sexual dimorphism, with males nearly twice the size of females. The global population is listed as "least concern" under the IUCN, although the populations of central Europe are declining and fragmented, or possibly extirpated.
Fun Fact
Male western capercaillies perform dramatic springtime displays — they fan their tails like turkeys, extend their necks, and make popping and grinding sounds while becoming so fixated on display that they're nearly oblivious to approaching observers.
