Deer 286 left the park less than 2 weeks after capture and within 2 or 3 
days after we disturbed her; perhaps we influenced the time of her movement. 
Her course of travel seemed to follow the Sangamon River and showed no relation 
to wind direction. 
Deer 266 also followed the Sangamon River, but she turned away from the 
main river and followed Camp Creek past ilonticello. If she moved 24 April, it 
was on a cool night that followed a week of warm temperatures. 
During this same cool period, deer 23$ left the park. Her course of travel 
did not seem related to wind direction nor did it follow a river. Some ideas 
concerning migration or homing to a traditional fawning area have been considered 
but are no more than speculation at this time.
