ing when the ground and vegetation were saturated with 

 rain or snow water, but even under these conditions 

 the rabbits were not easily captured. It was almost im- 

 possible to capture cottontails when the weather was 

 clear Snd the vegetation dry. 



The night-lighting rig was found to be useful for ob- 

 serving and studying the behavior of animals during 



nighttime. This study technique is particularly valuable 

 when many animals have been marked for individual 

 recognition. Observing animals with bright lights during 

 nighttime has promise as a method of obtaining prehunt 

 sex ratios of pheasants, but the validity of sex ratios 

 that have been obtained by this method has not yet 

 been determined.
