which have a sparse vegetation, due to frequent burning. A sparse, 
dry vegetation seems to be the deciding factor in determining the 
range of the sharp-tallod grouse. The sphagnum, slthough damp be. 
neath is dry on the surfact. During wet weather the grouse oould 
live on top of the dnea nte of latherleaf whlh grows extensive- 
ly in most bogs. In the West the sharp-tailed grse is more of a 
plains bird than a prairie bird. It Inhabited western North Dakota, 
western South Dakota, eastern Wyoming, Kansas, and Nebraska. Sine 
settlment It has mved eastward, probably due to cultivation, whioh 
has resulted in a sparser vegetation than formerly occurred. In 
Iowa the sharp-tail nested only in sandy areas where the vegetation 
was sparse, while the prairie chicken nested In the dense grass. It 
is probable that the sharp-tailed grouse did not nest in the original 
prairie areas of Wisconsin as they were probably mestly of the dense 
grass type. Rote also that the sharp-tailed grouse occurred in 
northeastern Illinois, which is the only part of the State that has 
sphagnum bogs. 
Food, Roost Cover, and Protective Cover of the Bog 
In Relation to $harp-Tailed Grus 
Jackson County 
Several flocks of sharp-tails were found In the vioinity of 
Birch Bluff in a large bog that f     a reservoir for a cranberry 
farm. As they may be so    here at all times of the year It is 
probable that a large bog provides everything that is neessary in 
the line of roost cow.er, protection aganst enemies and food for 
permanent residonce. However, bogs are generally bordered by 
swamps whiah furnish food in the form of alder atkins, white birh 
buds and catkins, willow buds and catkins, and mountain ash berries. 
The food eaten by the shar-tail in the bog proper consists during
