I. Pheasant Populations and Land Use W. J. Francis, S. L. Etter 
The majority of pheasants trapoed, markeu, and released on the Sibley Study 
Area during the period August 1964- larch 1969, and subsequently observed, moved less 
than 2 miles from the time of marking to the time of the first subsequent observa¬ 
tion (Table l). Only 14.4 percent of the pheasants were observed more than 2 miles 
from the location of marking, and 73-7 percent were observed 1 mile, or less, from 
the site of marking. Observations, either of live birds or based on returns of 
back tags, were made during the period August 1964-August 1965* 
Of the 753 pheasants marked during the fall of 1964 and the winter of 1965, 
31.4 percent were observed one or more times after trapping, marking, and releasing 
Table 1. Numbers of pheasants moving specified distances from original points of 
capture on the Sibley Study Area. The birds were marked during fall (August- 
November 1964) and winter trapping (January-March 1965) and were subsequently 
observed August 1964-August 1965**
