THE trapping techniques used in banding songbirds and waterfowl 
are readily available in Lincoln and Baldwin's "Manual for Bird 
Banders" (U. S. D. A. Misc. Pub. No. 58; 1929). In the case of 
upland game bird trapping, publication has not equally kept pace 
with the development of methods. Information on traps for Pin- 
nated and Prairie Sharp-tailed Grouse (Tympanuchus cupido amer- 
icanus and     Pedioecetes phasianellus campestris) is       particularly

lacking. Jihe purpose of this paper is to describe five traps which 
have been used for those species in 10-isconsin. All but one of 
these traps (No. 3) were used in our work on the Central Wisconsin 
Game Project' during the winter of 1936-37. 
Grouse trapping offers particular difficulties.       Pinnates, even
