ery, “ which resembled that of the Capercailzie.”” (Levin, Gfv. Kgl. 
Vet.-Akad. Forh. Stockholm, 1847, p. 201.) 
Most of the specimens which have come into my hands in a fresh 
state had no gun-shot wounds, and probably had been snared; but 
whether these were taken in snares together with Rype in districts 
frequented by the latter, namely in the regio alpina (the upper 
limits of the birch-region on the mountains), or with Zetrao urogallus 
and 7’. tetriz in the forest-regions, cannot be stated with any certainty. 
If remains of their food are examined it will probably be found that 
they more usually share the quarters of the Willow-Grouse than 
those of the other species. 
One of the specimens sent to the University Museum (from Sande 
Sogn, Nov. 9, 1881) was shot not far from the Christiania Fjord, in 
a district where the Lagopus albus certainly breeds, but in very few 
numbers, and this is hardly an annual occurrence, the locality being 
comparatively low. The sender of this bird, who regularly received 
game from that place, deemed it certain that it had been captured 
along with Blackgame, as it was forwarded to him in a bunch of 
these birds, and he never received Willow-Grouse from there. 
Food. 
In some of the individuals opened by me the food was still 
partially or wholly entire, and consisted of the following :— 
1. Male, Dec. 7, 1870: a number of fragments of a Salix (15 
millim. in length), fragments and numerous berries of Myrtillus 
nigra, tops of Calluna vulgaris (about 30 millim. in length), and a 
few leaves of Arctostaphylos alpina. 
2. Male, Dec. 6, 1872: tops and seeds of Carex stellulata, a few 
berries of Oxycoccus palustris and Juniperus communis, some of the 
latter in an unripe state. 
3. Male, Feb. 28, 1873: leaves of Vaccinium vitis idea, fragments 
and buds of a Salix and of Myrtillus nigra. 
4, Female, Jan. 1875: a number of ripe and unripe berries of 
Juniperus, also a number of the peculiar bunchy leaves of that 
bush, in which Cecidomyia juniperina had formed their capsules; a 
large number of stalks of the Myrtillus nigra (about 12 millim. in 
length), some leaves of Vaccinium vitis idea, some old female and 
many young male catkins of Betula glutinosa (the mountain form, 
alpigena), and, lastly, the twigs of a haired Salix (S. glauca’). 
5. Female, Oct. 7, 1876: some berries of Empetrum nigrum, also 
stalks of Myrtillus nigra. 
6. Male, Dec. 27, 1879: leaves and berries of Oxycoccus 
palustris. 
7. Young male, autumn, 1880: berries of Oxycoccus palustris, 
also the top of a Carez. 
From these examples it will be seen that this hybrid both in 
winter and summer derives nourishment from about the same 
sources as the Willow-Grouse, namely stalks of willows and bilberries,
