The majority of pheasants trapped, marked, and released on the Sibley Study 
Area during the period September I 962 - February I 963 , and subsequently observed, 
moved less than 2 miles from time of marking to time of subsequent observations 
(Table 1). Only 10.0 percent of the observations occurred more than 2 miles 
from the location of marking, and 77*6 percent were made l 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 September 1 96 2 - April 1964. 
Of the 2,169 pheasants marked during the fail of 1 962 and the winter of 
1 96 3 * 52.7 percent (1,144 different individuals) were observed one or more times 
after trapping, marking, and releasing.
