GROUSE, PARTRIDGES, QUAILS, ETC. 131 



berry patches. In winter, flocks of sometimes a hundred or more 

 wary old birds gather together, but they light in the treetops to 

 inspect the horizon for danger before settling down to breakfast in 

 the cornfield, or else fly from their soft beds of snow to some big 

 open field where there is not so much as a bush or stick to hide a 

 lurking enemy. As the snow gets deeper it only brings them up 

 nearer the berries, haws, and buds, which furnish the bulk of their 

 winter food. When the snow hardens to a rigid crust and a few 

 patches of bare ground appear you hear just at sunrise a low boom- 

 ing sound, perhaps a mile away, answered by one after another of 

 the awakened cocks. This will be heard for hours every morning 

 from the last of February till the first of May in the grouse country, 

 for then the birds are having their famous dances. A few cocks and 

 hens gather on a frozen lake or the open prairie, and the males fight 

 and strut and boom in ardent rivalry before the apparently uncon- 

 cerned females. They inflate the orange air sacs on each side of the 

 neck, spread the yellow fringe over the eyes, and with widespread 

 tail, drooping wings, erect neck tufts, and lowered head emit the air 

 with the low booming sound. The booming is kept up throughout 

 the breeding season. It is a most deceptive sound, at twenty feet 

 often seeming far away, and at a long distance sounding close oy.

GENUS PEDICECETES.

 distensible skin, reddish in the breeding season, over which lies a series of

 spicuous fringe of horny processes in winter ; tail much shorter than wings, 

 graduated, feathers square at tips, the middle pair projecting much beyond
