Lives mainly in coniferous forests, especially at higher altitudes: in sparse woodland rich in undergrowth. In summer and autumn it can also be seen in the alpine moors of whortleberries and rhododendrons, not to mention green alder bushes, which it uses as shelter.
The male has a wingspan of 70-80 cm and bright blue plumage, with white under its wings and tail, white bars on its wings and a forked tail. The female is reddish-brown with a smaller wingspan than the male. It feeds mainly on berries and shoots. Nesting of the species has been confirmed in every valley of the park, from the lowest altitude of 1400 m almost all the way to the timberline. The species is periodically censused, based mostly on the count of the animals present in the "lekking" areas.
