ID tip

Male and female western capercaillie can easily be differentiated by their size and colouration. The cock is much bigger than the hen. It is one of the most sexually dimorphic in size of living bird species, only exceeded by the larger types of bustards and a select few members of the pheasant family. Cocks (males) typically range from 74 to 85 centimetres (29 to 33 in) in length with wingspan of 90 to 125 cm (35 to 49 in) and an average weight of 4.1 kg (9 lb 1 oz). The largest wild cocks can attain a length of 100 cm (40 in) and weight of 6.7 kg (14 lb 12 oz).

About the Western Capercaillie

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.
