2. Manipulation of 
Pheasant Habitat 
G. B. Joselyn 
The 
first search 
for pheasant nests 
on manipulated and 
control plots along 7 
mi les of 
roadway on 
the Sibley area was 
started on May 23 and completed on June 5« 
Equal numbers of pheasant nests (27) were located on manipulated and control plots 
(Table 3)» However, by June 30, 9 (33 percent) of the nests established on seeded 
plots had hatched compared to only 4 (14 percent) of the nests established on con¬ 
trol plots. If active nests on both types of plots ultimately hatch, the hatching 
success of nests on seeded plots will be 36 percent compared to 18 percent on con¬ 
trol plots. The second and third searchings of the plots will be conducted during 
the first and fourth weeks of July, respectively.
