Chapter 01
Overview
The rock ptarmigan (Lagopus muta) is a medium-sized game bird of the grouse tribe, known simply as the ptarmigan in Europe. It is the official bird of Nunavut, where it is the aqiggiq, and the official game bird of Newfoundland and Labrador. In Japan it is the raichō, 'thunder bird', official bird of Gifu, Nagano and Toyama prefectures and a protected species nationwide. The species name muta is Neo-Latin for 'mute', after the male's simple croaking song.
Chapter 02
Identification
34–36 cm long with an 8 cm tail and a 54–60 cm wingspan, weighing 440–640 g — about ten per cent smaller than the willow ptarmigan. It is camouflaged to the season, moulting from white in winter to grey and brown in spring and summer. The breeding male has greyish upperparts with white wings and underparts. In winter the plumage turns completely white except for the black outer tail feathers and the black eye line, which is the mark that separates it from a willow ptarmigan in the same country.
Chapter 03
Behaviour
Largely sedentary, particularly in isolated southern populations such as Japan and Scotland, which manage no more than limited altitudinal movement to lower, more sheltered ground in winter. Further north it disperses more, and in the Arctic the movements are considerable — birds have been found wintering in Iceland with Greenland-origin minerals in their gizzards, having crossed the 300 km Denmark Strait, and one ringed in summer on Disko Island off western Greenland was recovered over 1,000 km away. Food varies enormously by region. In Alaska the winter staple is aspen buds and dwarf birch and willow buds and catkins, shifting in spring to crowberry and lingonberry. The greatest variety comes in early summer — willow leaves, the leaves and flowers of mountain avens and locoweed — with berries, bistort seeds and birch buds from late summer.

Traditional preparations
- Icelandic festive ptarmigan
- Rock ptarmigan meat is a popular part of festive meals in Icelandic cuisine. Hunting was banned there in 2003 and 2004 over a declining population and has been allowed again since 2005 on selected days revised yearly, with all trade in the bird illegal. Grouse — Wikipedia
